Had a bash at making a bearing installer thing, threaded rod, coupla nuts and some big washers, around $10 all up. Sort of worked... Went a bit skewiff trying to do both sides at once. Was trying to get it done at lunchtime so was rushing things a bit, and the bigger lower bearing shell got a bit angled, so I knocked it out again and put it in the freezer. Got top one in anyway so will have another go after work...

So with that parked up did a little more on the TT. Checked out the m/c I got from eBay, looks in good shape... Got the tricky little circlip out without the right tool after a bit of swearing fiddling... And gave the caliper another go, the pins were pretty well stuck with dried grease, but got them apart. Boots look ok but think there are some clips missing... And gave it a good cleanup, cleaned the seal grooves with some cheap Ali brushes. Worked well enough but shed a lot of sharp little spines... Then had a go at putting steering head bearings in. Failed miserably. so gave up and had tea. Then I wanted a clean job, so pulled each wheel spoke to lube threads. Quite like jobs like this, esp with Jon Toogood's 'Planet of Sound' going in the background - really enjoy that, the bloke has great musical taste... And it spins pretty true. Prob needs another 20 mins to sort properly, will ping each spoke to check tension by tone and re-true...

In the middle of pissy rain shot down the beach for a run on the TC and a mate's old TS250... Only got to 85kph but it felt like a lot more. The old farm bike suspension was bottoming out on the humps left by the tide. It's bogging at full throttle so I've since adjusted the pilot mix screw (shouldn't make any diff at WOT) squeezed excess oil out of the filter and tightened the carb fixing. might give it a run on the road this week to fettle, but riding the Nevis next weekend (hopefully) so won't need a top end speed, just want it to keep going...
-
Looks like the full toolkit is in there... And was going to put new set of points in, but may have to remove magneto...? Not keen to get too far into it if it's running tbh... And more bits for the TT arrived, no real excuse anymore just gotta pick something and get into it...
-
Yeah old forum is dead, all web searches direct you there. They've set up a new one though and are migrating info over. Scored a TS TC100 service manual copy through it so that's a win...
-
And hooned the TC tonight. Hit 90kph going round to a mate's place, plus it has brakes (dropped it during brake test and snapped off original suzuki mirror). Pretty sure I'll make the metric ton if I give her a few tweaks. Really trying to find some service manuals online but haven't had any joy. Tried to join a TC forum but having difficulty registering. Might have a Barry-blocker... Sent one of the moderators a message so will see how we get on...

TC again. Had a go at making an air filter, must be cheaper than buying obsolete real ones... Not too much science in it... Used a JB superglue that came with a brush for applying to the foam. Next one I'll oversize slightly as pinching it together while the glue set made it a bit snug... And oiled up. never used proper foam oil before, used the plastic bag and squeeze method... Man that stuff is sticky, usually just squirt some 20W-50 on, but the blue sure makes it easier to see where it has covered. Seems to have worked ok, will prob make one for the TT similarly, although that's a harder shape...

Yeah heard he'd died. Called in there once yrs ago, very knowledgeable on Brit bikes...

Rim Nice new bearings, rim and spokes all ready to go, how hard can it be...? Fucking hard, forgot how tricky this can be. Had a few goes at getting the under/overs right... But got there in the end. Only loosely fitted, I've gotta lube the spoke threads before truing it up yet (cos I was doing it inside didn't want to get messy anti-seize everywhere)... Actually did it twice, first time looked right, but the spokes were going a different direction to original, Good pics of original wheel helped get it right...
-
Back to the TT. Steering stem lower bearing was a bastard to get off, came pretty close to giving up and getting another one. Tried gentle heat first cos I wanted to save the lower seal, no go... Then welded some blobs on, usually the heat loosens it and some decent whacks on the weld will shift them, still no go. Actually bashed the welds off, fractured the bearing metal beneath... So out with the Ali diamond cutting disc and dremel... This worked, cut a decent slot then smacked a large screwdriver into it and it cracked loose. What a lot of effort for a small job...
-
I always start quick. Completion rate not great however... Anyway, spent this morning on the TC. Thought I'd check the front brakes as there was bugger all there on my high speed runs. Pads looked like they were varnished. Luckily I had a new set in my box of random bits, so thought it'd be a 10 minute job to swap out... But drum was full of oil. Scratched my head where it was coming from then discovered fork oil leaking from the bottom allen head screw and tracking into the drum. Bugger, meant I had to open forks up, I wanted to avoid that as they seemed to go up and down semi-ok. The muddy state of the remaining oil meant it prob wasn't a bad idea anyway... And disassembled. I just take pics so I can remember how it goes back together, thinking it would be a few days till I get some seals... The old ones were fairly well stuck, (45 odd years in there) but came out ok with a tyre lever... And bugger me, local Suzuki shop had seals in stock. Grabbed some oil too, spec says 5W but I went 10W cos it's a wee bike and I'm a wee fatty... And all assembled again, a good day's work, and they do feel much better. Can't put brakes back in unfortunately cos need new oil seal, ordered one in bike shop while I was there... Good practice for checking the TT forks anyway...

Mix of eBay US, Partzilla and Ali. Used youshop to forward packages from eBay sellers. Just went round the block on the TC. Going much better, 86kph and prob more to come...
-
And back to main topic, rim arrived from Ali today, looks ok, might get laced in the weekend...

[Now with added two stroke] So was trying really hard not to get distracted, but heard of a bike run coming up and since the TT won't be ready, dragged this old girl out of the shed, a '74 TC100. Had it for years, just been sitting there unused and thought it'd be a hoot to ride. Bloody thing burst into life on third kick... And a test run round the block indicated some issues, wouldn't get past 72kph, and was hesitant on acceleration, so ripped into a cleanup/service. Plug was wrong type but was a good colour... Pulled oil tank and carb. Discovered original tool bag and spare fuses all there... Drained watery old trans oil and put fresh stuff in... Carb looked bloody clean, but disassembled, cleaned and blew out passages anyway. Discovered there was no spring on the pilot screw and the whole carb was a bit loose on the intake. Bodged a spring, set float level and reassembled/installed... And also cleaned/lubed the throttle and choke cables, and cleaned old oil tank. Hope to take for another run this weekend to see if it goes any better...

First consolidated package arrived. Love getting parcels of bits. Should be a few more coming soon..

Did you get in trouble borrowing your Nan's curtains...? and 'Talk about mud flaps my Dub's gottem'... -
Still tidying. Took a break from garden shit to knock up a bracket to hold my golf trundler. Couldn't find anything big enough so narrowed some old 10-speed bars... A lick of paint... And it now hangs in the cupboard out of the way... So that's another little bit of garage space feed up...

Misc parts So this model was a bit obscure, seems most of the world had the SOHC TT225, whereas Aus/NZ/Japan had the DOHC TT250, similar to the 350/600. Aussie websites have part number listings for the 250, appears most chassis parts seem interchangeable with the 350, the SRX250 used the same engine, and many parts appear to be common with the XT. So I've ordered a bit of gear from all over the place - gaskets, grommets, sprockets, etc, plus a clutch cable from Aus, and assorted missing/worn bits. Surprisingly, Youshop works out ok when you're buying a lot at the same time, a large consolidated package costs around $40 delivery, which isn't bad for 12-odd packages... Swingarm seems in pretty good nick so far (haven't looked at bearings/bushings yet) but the plastic chain guides need replaced and are hard to find/$$$. I found an entire swingarm on eBay for $39 with all plastics on it, so bought that and was $50 to forward it to NZ (not too bad). Looks pretty good and the plastic parts are in great nick... Wheel = well poked, obviously split externally but was amazed at the corruption inside after I finally wrestled the old tyre off (was hard AF)... Tried to get all old spokes out in one piece to re-use if possible and was going really well using sprays and heat (plus a good spoke spanner) till I snapped one, so gave up and grabbed a new spoke set. Then after looking at what was available locally I bought a 21" rim from Aliexpress, will see how that goes after it arrives and I lace it all up... Some parts are stupid expensive or unobtainable, so looked at what I could use instead. The rubber cap on the steering stem will keep water out, so after a measure up I found rubber bike bar ends will fit, 83c on Ali for 2... A rear fender tool bag would be nice to have, but I'm not paying $50 for one. Found this though, a red cosmetic bag the perfect size for $12 from Ali. Just have to remember to replace the lippy with a plug spanner... Ordered a full set of brake pads (Fr and Rear) for $22 from Ali, and high capacity Koyo headstock bearings from eBay. You can get cheaper bearings but they're something I don't mind spending money on. Bought a seat cover and bash plate on tardme, and this spare parts carb from Aus, looks to have the bits I need... So doing what I can while parts are in transit, hopefully it won't get parked up (like other projects) and I'll get it running reasonably soon to hoon. there's quite a following with old dirt bikes now and they seem to have some good runs...

And got a coat on after work, the durepox sticks bloody well, I'll just put a few coats on and see how it goes as a top coat. It's only a trail bike, will just touch up as it get dings and scrapes. And frames are buggers to paint, all nooks and crannies. Balanced it on the old cable drum and did the under side before hanging up to get the top and sides done... And it's red again. Not a bad match for the original colour either... That's a win, always good to get paint on a blasted surface asap, hopefully I'll get another couple of coats on tomorrow and it'll be all good to start putting bits back on... [edit] and finally mixed just the right amount of paint, usually run out or have far too much. Made up mix to150mls then added 20% reducer to 180mls. Almost the perfect amount...
-
So picked frame up yesterday and warm today so thought I'd get some primer on at lunchtime, which was a bit optimistic. By the time I'd found everything I needed I had to get back to the orifice. Also, my hardener had, well, hardened, so had to grab some more on way back thru town... Still, managed to tidy up some old and ugly repairs that were noticable with the paint off, will try to get some colour on it tonight while weather is cooperating... And wife away so can use handy backyard rotary frame (prob should take washing in first). I'm sure the kids can feed themselves while I'm chucking paint...

It's the twin port and airbox setup that worries me if I changed carbs. Think there is a Kwaka set that fits the 350? Really cant be bothered setting something new up. Had a go at drilling out that jet tonight, need a M8 x 1.0 tap to run thru it to see if I can clear the remnants and recover the nozzle. Trouble is I can't tell where the jet finishes and nozzle begins so don't know how deep to go. Good news is I scored a damaged 250 carb on Aussie eBay so should get something sorted...
-
Might have to do that, had a go at that jet today with heat and an ezyout and still stubbornly stuck. Prob have to try drilling it out next without damaging anything else...

Wheel bearings... Was really struggling to get the rear wheel bearings out, I usually manage to tap them out with drifts I've made up out of big old screwdrivers, but these ones refused to budge, and I had bugger all lip to drive against. Looked at blind bearing pullers (spendy) then realised it was a 20mm bearing, so tried a 20mm dynabolt... Worked a charm. Just inserted bolt, tightened the nut to expand it a bit, and bosh, one smack on the other side and bearings popped out on the ground. Great result for a tool that cost $7.42...
-
Carb... Frame went to be blasted yesterday so I looked at carb last night. These use the Yamaha Dual Intake system (YDIS) essentially a vacuum secondary, and theory is that from half throttle the secondary carb opens up. Unfortunately they are a weird Teikei model and not easy to get bits for. This view is from the engine side looking out... Looking at the port colours it seems the secondary side may not have been opening too well...? Toyed with replacing whole carb but no real information on any bolt-on options, and can't be arsed working it out, so decided to give this one a clean and see how it goes (ordered a simple gasket, o-ring, float needle kit). Pulled float bowl and doesn't look too bad, have definitely seen worse... Separated the primary and secondary sections easy enough... And got the pilot jet, main nozzle, jet, and pilot screw out ok, although the float needle seat doesn't want to move, didn't want to force it till replacement arrives... Main vacuum diaphragm looks ok... As does the enriching system diaphragm... And the drain plug on the secondary was a right bitch to get off. Didn't want to file flats in it as these are unavailable, so gentle heat, a bit of tapping and the right sized screwdriver got it out (don't think it has ever been off, looking at it). The main jet however will be a problem. Hit it with lots of spray and tried unscrewing it, felt and sounded like it was coming but when I looked I had just twisted the head slot off. Bugger... Think these are #136 sized too for this model (looks a fairly big hole) and none of these seem available. I've ordered a 120 and 125 so at least I'll have something to put back in if I manage get it out. The nozzle behind this is unavailable too (naturally) so will be a bit tricky. I can see an ezyout being carefully used trying not to fuck anything... And at least I can clean up all these bits to get ready for reassembly while I wait...

The kickstand hole was flogged out, hate a wobbly stand so I cut a plug out of some 10mm waste, chamfered both sides and welded it in place. Used a hole saw so there'd be a hole bang in the centre for drilling out to fit the pivot bolt... Bloody pleased with that weld, nowhere near as much grinding req'd as normal. Then realised I didn't have a 14mm drill. So ground down a stupidly large drill bit I had. Test drilled a piece of alloy and it seemed to work ok... And it's round again. Slightly undersized hole so will test with the new pivot bolt I've ordered, and ream if required to make a neat fit... And drilled the cross piece I welded in earlier (I realise there's one less hole than there should be). Now frame should be ok to get sandblasted...
