  1. bmw R80 scrambler project

    ok, not long ago i bought an 1989 r80rt monolever beemer, i was actually looking for an older r80/100 gs-pd or older g/s air cooled for a scrambler project the reason was they had the wire wheels, and i detest the cast wheels on these old beemers, but they were going for stupid money here in the uk, and then this old rt came up for about 1/3 my budget of what i was willing to pay for the gs model, so i thought fuck it, i can some how make it spoked, i was going to change the front end of the gs any way, so that would only leave the rear wheel that would need some thinking about, so anyway, collection, i had to drive down into england to pick up a bath room for the old merc camper, and this bike was kind of on the way, in so much as it was south of scotland met up with the guy, paid him the money and would return in the after noon to collect after getting the bath room, all was good did that and rode back to edinburgh with no issues, the rt models when they came out looked like this whoa, super ugly fairing massive screens etc, perfect tourers, but one of the ugliest beemers ever mine didnt come with the fairings (previously crashed) which suited me just fine also the guy changed the rocker covers from the flat newer style to the older skool ones no really fussed either way, i had already ditched the tail section and gave it to a mate, as ill be completly changing the back end any way the plan, 1 change the rear wheel to a r100gs wheel, i bought that already and as we speak its being machined down to fit the monolever hub (there is no straight replacement wheel, but the gs wheel is close enough, and just requires 21.25mm (in my case) to be machined down inside the wheel itself) so no biggie after that will be the front end or exhaust ill be using a usd front end of un-known manufacture as a replacement to the stock beemer forks wheels, triples, etc, probably a drz or crf may be some white powers, price will determine that, the exhaust will be a high level custom made running high from the start either 2-2 all the way through like a cl360 or 2-1 like this unsure yet i will also raise /drop the swing arm and probably move the mount onto the steel part of the swing arm and possibly lengthen the swingarm to gain a bit of extra travel im going to try and get it look a bit like this but obviously a monolever, with exhaust on 1 side only, and usd forks yeah, so, this will be a long-ish project, im a bit low on funds after bumming around europe in the campervan for the summer, and skiing all last winter, really should start looking for a job
  2. bmw R80 scrambler project

    stock location for some models, handy because alot of the wiring can be hidden in the headlight
  3. bmw R80 scrambler project

    yeah dunno whats up with that, its the stock signal that the bmw clocks got, i could try the signal from the other cylinder i suppose and see if thats cleaner. also have to replace that shit start switch as well.
  4. bmw R80 scrambler project

    right got the speedo all hooked up, bike is running pretty good although runs out of gas at high sustained revs because of the stupid floats, ordered a set of plastic ones out of the states to replace the shit foam ones that sink, fucken bing and their stupid ideas, took the bike for a mot (wof) on friday and it went through no bother, heres a shit video of a wee thrash, had to hold the camera in my mouth so... ill keep ya posted, have also front mudguard to go on at some point. and a leaky fork seal (gayest job on a bike)
  5. 7 years ago i bought and rebuilt a mini buffalo which turned out to have a bridgestone 60cc engine fitted (rotary valve 2 stroke single) wtf bridgestone as in the tyres guys??? yep. duning the 60's and 70's they made and competed very sucessfully with motorbikes read the history and demise of the bike division here anyway its taken me 8 years to find another bridgeston. ive now moved to scotland and managed to find a mkII rs that had been imported from the states along with a bunch of rd350's the guy who bought it over had no interest in it so sold it to me, it was produced in december 1968. (1 of 7800 built) mk11 rs200 dual rotary valve induction, twin cylinder 2 stroke, pics so the good bits are its pretty much complete, its only done 2900 miles. paint is ok and has a cool patina frame is in excellent condition bad bits are, its been sitting for 40 odd years its seized solid, all the rubber bits are perished or missing front brake lever is busted, my plan is to get it running, by doing as much of a rebuild that is necessary, i wont be touching the paint, as i dont want a show bike, replace any missing bits, get it registered over here in scotland and ride it. im guessing im going to need: rings for both cylinders top and bottom bearings, new conrods, and new crank pins, piston pins, all new internal bearings new chain and sprockets, rubber carb boots (carb to airbox) tanks rubber knee pads, new tyres, and probably a rebore/re-chome depending on barrel type . i'll post photos as things happen (which may be a while, in the midst of moving house at the moment)
  6. bridgestone mkII rs200 project

    well the seat is back from being recovered. its not the same style as the original, which is a bit shit, but its a good job, so meh, i doubt any one would notice ill take it to get a mot in another couple of day and then send all the paper work off to get a new plate for it. free tax on the bad boy too
  7. bmw R80 scrambler project

    ok, cleaned up all the wiring, replaced the lighting relay, and the indicator relay, led indicators got added to front and back, the rear light has them built in, but they were a little to close together for my liking, old front ones were shit, so got replaced as well, have added waterproof plugs for the new digital speedo thats on the way from the fatherland. so that'll just be a matter of adding the plugs to the speedo loom and she'll be plug and play. had to also replace the ignition switch, from last time some little chavy prick tried to steal it ummm balanced the carbs, need to order a front brake switch, hobble together some sort of front mud guard, and she'll be good to go for a mot (wof) i think ill go for a fang tomorrow and do a oil and filter change, i also have a leaking final drive, so that'll have to be fixed at some point glory shots
  8. bmw R80 scrambler project

    well its been a couple of years and ive done bugger all to the bike, after the gear box was done, i literally parked it up and have not started it since. as punishment for blowing up on me in the first place i got the tank painted about a by my workmate and told him to do what ever he wanted. and this was the result a nice copper pearl type... thing in the paint, all flickery and shit. awesome job i must say, i pulled the carbs off and replaced all the jets and gave them an ultrasonic clean, replaced the diaphragms etc i also decided it was high time i ditched the master cylinder, (as its set up for a twin caliper front end) in order to do that i needed to replace the throttle, starter button and master cylinder, which also gave me the opportunity to re-design and custom make some new throttle cables with a 90' bend into the carb so it avoided the exhaust im waiting on a new/2nd hand ignition switch because some little tard tried to steal the bike, not realising that it had no gas and none of the fuel lines were connected, the little fucks did get away with my ktm super moto though fuckers any way while im waiting on the ignition i though i best see if this old dog would start after 2 years of just lazing about, like a gypsy bum on the dole see here for the results ....
  9. bridgestone mkII rs200 project

    well, after a successful brew i was in no fit state to go for a ride on any bike, order of the day was a drunken lunch time nap, last batch of hops added to the mash ton. doesnt look very appetising i admit but sunday was a good day, first i took pinky (b120) for a ride to find it was running out of gas at full throttle, so pulled the carb and adjusted the float, another spin and she was bang on, even managed to get to 55mph on the flat hehe next on the cards was wee red (bridgestone) had to replace a buggered exhaust gasket, then decided id take her for a spin with out the seat, ran like a champ!! managed 80mph on the clocks and pulled pretty well getting there, big red (vtr) got a start up a wee run, as well, just because it'd been such a fruitful day blacky (bandit) didnt get any love pics for thread
  10. bridgestone mkII rs200 project

    right, i took the seat to be recovered, so that'll be away a week or 2, also spoke to the vintage japanese motorcycle club (vjmc) about dating the bike for the dvla (vtnz in nz, dmv in the states) so that got done pretty painlessly still waiting for the dvla to send out the paperwork for me to fill in and send back (frankly astounded you cant just download the paperwork, british bureaucracy at its best, of course they've also shut down all their offices so you cant just pick it up either) so while i was waiting, i thought id work on the mrs suzuki B120 of 72 vintage. (not that she has ever ridden it, but she swears she's doing her licence this year.... ) it hadnt been started in a couple of years and last time i rode it, the fuel would piss out the float bowl, or alternatively run out of fuel because the bowl wasnt full enough. and since the carbs are almost the same as the bridgestone i thought id steal a float from one of the 4 spare carbs i have, and put that in, also uses a 95 main jet as well which i had a few spare, so a new one of those went in, put it back together, turned on the fuel, and... first kick after 2 years. might take it out for a spin if im not to drunk after ive done my beer brew in the morning. so probably wont take it out for a ride i really need to sell my vtr and buy another 2 stroke,
  11. bridgestone mkII rs200 project

    Well, I replaced the main jets on both carbs. And gave them a blow through in case more shit had managed To get stuck in the passages. No one likes a blocked back passage. Everything was clear so I gave it a kick over I love how this thing starts first kick. Can't/won't take it for a test ride, as it's currently snowing here in Scotland. Tell ya it was a manic ride to work on the bandit this morning. More side ways action than I prefer on 2 wheels. One of these days I'll buy a car/ute for the winter. Not today though
  12. bridgestone mkII rs200 project

    oh for sure, id have been pretty upset if it had fucked the barrel, i have another set of standard carbs that i had forgotten that id bought as well, so i can still try them at some stage. at the moment there is too much snow here to take it for another test ride. onwards and upwards
  13. bridgestone mkII rs200 project

    i decided id change back to the original carbs for a test. the new carbs had a piss poor bottom end, but a really good top end, so i chuck on the carbs, starts first kick as always, take off and the bottom end feels great, but i get to the top end and it feels pretty crap, couldnt get above 55mph and way coming back up the hill to my place and a cylinder drops out and starts running on one, i thought it was the condesor arcing out on the cover (its happened before) but it felt considerably free'r revving, parked it up and let it cool down before looking at it. first thing i did was pull the plug, it had crap built up on it..... oh... nooo..... put my finger on the plug hole and pushed down the kick start..... noooooooo!!!!! compression = 0 pulled off the head to be greated with this tale of woe luckily in my arsenal of spares i had one piston that was in good shape, with 1 good ring, exactly what was needed so swapped it all over and happy days most importantly my stupidly expensive ceramic coated barrels were still in perfect nick, not even a hint of a scratch (thank Hesus) heres a couple more pics of the semi destruction so one can assume that the main jet on the left cylinder is blocked, and it was just running on the pilot jet the whole time, much leanness = very hot very hot = burny hole to piston burny hole to piston = sadness so therefore much leanness = sadness, better to be a bit fat
  14. bridgestone mkII rs200 project

    yeah it seems to be, bear in mind the bike has only done 2000 miles since new, so the baffles arn't carboned up at all, they have just rusted a bit, and now broken inside 1 side. fuck knows how im going to get that retarded piece out. i think with a bit of work with the needle clip position, it should be running pretty well, was quite funny, i was hooning up the street with the one baffle out and a couple of builders came out to see what all the noise was about
  15. bridgestone mkII rs200 project

    ok partial success,its running loads better managed to get to 70 before one of the baffles came flying out and i stopped to turn around to pick it up, the other baffle in the exhaust is broken off inside the exhaust and only half of it is able to come out, not really a problem for now, but will become one when it gets coked up with carbon and i cant remove it. its still a bit shit down low getting off the mark. unsure if this is a carburation issue or if its the characteristic of the bike. ill post a video riding it once i figure out how to hold my phone and ride at the same time
  16. bridgestone mkII rs200 project

    well there is that. i can easily pull the case to air box tubes to allow more air flow and see if that makes a difference. i should really get a new air filter, surprisingly the 50 year old one is still holding together i gave it a quick start straight after work, it sounds and revs crisper with the new rubber gaskets, ill take it for a ride after ive had a coffee and a smoke.
  17. bridgestone mkII rs200 project

    well something isnt quite right in the force, starts first kick, idles fine, but its seriously down on power, like id say 5 or 6hp not the advertised 20hp. i thought i'd change out the carbs as i couldnt get one of them to stop pissing fuel so got some genuine mikuni vm18-144 going from the stock vm17-18 they are pretty much the same. i tried the stock 95 mains with 15 pilot = no better tryed the 70 mains with 30 pilot that came in the carbs (another bridgestone rider skiri251 has had success with setup) its certainly better than the 95 mains set up but topped out at 45 mph and couldn't even hold speed in top gear ive had problems with some aftermarket exhaust gaskets sealing... mainly because the pieces of crap melted yep quality so i got a set of genuine old stock bridgestone ones to try out so thats where i am. compression is bang on, spark is good, fuelling is where it should be.. may be. timing is as close as i can humanly get it. ill post ride with the new gasket rubbers i dunno though, my little kawasaki kh125 rotary valve would eat this for breakfast at this stage. even my little piston port suzuki b120 is quicker.
  18. bridgestone mkII rs200 project

    right ive kind of been slack, but, ive got most of the bits now to finish this, i put new tyres and tubes on, the rubber knee guards are fitted, had to fluff around with the timing quite a bit, i was miles out in the end, ive got it as close as i can with out a timing light, but it now seems to start first kick and doesnt piss petrol all over the place now, still to take it out for a run, but heres a cold start up video ill keep ya posted. post shake down ride
  19. bridgestone mkII rs200 project

    well in other news, some little retard broken into my garage and stole my bandit 600 commuter, thankfully they left my bmw, suzuki b120 and bridgestone alone, still an arse, so this months pay has been diverted away from bridgestone matters into a new commuter. not exactly what i was after to use as a winter hack in scotland, but the price was too good to pass up. 2001 vtr1000
  20. bridgestone mkII rs200 project

    well the vinegar worked ok, but not aggressive enough, but this is the clour of the crud that came out so i bit the bullet and got some "deck and patio cleaner" (hydrochloric /Muriatic acid) it was 20% some of the pool stuff is around 36% worked great, did a better job in a hour than what vinegar did in 2 days so in celebration of having a clean tank, i jerry rigged the fuel lines and attempted to start the old girl! half a dozen kicks and she fired to life. great success
  21. bridgestone mkII rs200 project

    lol. you'd think living in scotland id have a dryer.. nope. everything gets "dried" in front of the dehumidifier
  22. bridgestone mkII rs200 project

    so far, fairly under whelming, its definitely pulled some rust off, but its only 5% acid, so.... it'd probably take a while,
  23. bridgestone mkII rs200 project

    not much happening, as im waiting for parts, (and an email back from richard ) so i decided to see if i could clean out the rusty tank internals i looked on youtube, and the consensus was vinegar if you didnt mind waiting, or Muratic Acid (swimming pool cleaner/ Spirit of Salts / brick cleaner) since my local hareware shop was closed i decided to just get some vinegar and see how it goes, also decided to chuck on the chain, and sprocket cover, and highway gear selector hopefully my new fuel tap will arrive tomorrow which is actually a kz900 unit, whilst not identical to the original, its close enough
  24. bridgestone mkII rs200 project

    ok where was i, i degreased the frame and gave it a general tidy up. put new shoes in both drums, changed the fork oil and seals got the bike back on its wheels again and fitted the engine ran the cables, and connected carbs up connected all the electrics back up, best bike ever for wiring, see a wire, connect it to another wire of the same colour, and repeat, was so easy, no stupid indicators,, and a cool old school rectifier, plus the coolest brake switch ive ever seen then chuck the tank and seat on, then connected the exhausts, and kick starter and gear shift, so thats where i stand, ive got to get a few bits before i can attempt to kick the old girl over, fuel hose, fuel tap, 2 stroke oil, engine oil, battery acid and then charge the battery, at some stage i will need to get. new tyres, new throttle cable, throttle grips, new tank pads (missing from original parts order) kick start rubber, gear change rubber, foot peg rubber
  25. bridgestone mkII rs200 project

    right, i managed to get the generator rebuilt, im pretty fucked off though, the parts i ordered for it, new cam, points etc were all for the older model which had a big gear which spun at half the speed. so the cam needed to have 2 lobes on it, where on my model they put in an idler gear and a small main ger to get it to do a single rotation for every rotation the engine did, i ordered the right parts but the wrong parts turned up, this was a year ago, so didnt notice till now, och well, cant do much about it now, old cam back in ;( so i got it in place and spent a supid amount of time getting it timed up, mainly because i cant tell my left from my right, and was timing the wrong cylinder then i went about rebuilding the carbs, setting the floats etc cleaning everything again, and fitted them so thats it for now, engine is now fully rebuilt and ready to fit back in the frame, but first ill degrease the frame from its 38 year old grease and muck, change the fork oil and probably seals change the front and rear shoes, and check all the bearings etc, and order a new chain for it as well, the end is neigh
