  1. I'm gonna have a crack at rebuilding the crank myself. Allen Millyard has a very confidence inspiring video on rebuilding his H1 crank. I've got 2 H1 cranks and a couple of twin and single cranks in my list to rebuild. So if I can learn how to do it, maybe I'll be the next two stroke crank guy in NZ? probably not. But at least I won't be paying someone else top dollar to fuck it up! Only have myself to blame. Gonna use the money I'd spend on rebuilding a crank buying the required tools etc. As for machining the cases, looks like I can get a tidy set of cases between $400 and $600 to my door. I very likely won't get any change out of $18k getting that stuff machined locally. Every experience I've had with NZ people in the trade seem to: Have a "I can't be fucked" attitude like they're doing me a massive favor or something. Dude, I'm paying your for a service! No need to be like that! Be eye wateringly expensive Or they fuck it up anyway and I have to get it redone or buy a replacement So I'm very reticent to pay someone to do it (repair cases or rebuild crank). When at least if I do it and fuck it up, I've only got myself to blame, and I haven't outlaid heaps of money for the privilege.
  2. I stripped the engine down to get the crankshaft out. Oil check valves are definitely chooched: Bloody murder! Guts out: Not only were all the crank seals as loose as chatter rings, one of the bearings had completely collapsed. You can see it next to the stator on the right side of the crank in the above pics. I'm amazed this thing ran at all. However, there is some bad news... Because of this collapsed bearing, its actually had been spinning in the crank cases and has wallowed out the bearing surfaces.... Shits dicked jim. Theres about a 0.5mm lip there. I know there are various ways to fix this, like peening some divots in the surface to raise it up then locktite 620 the bearing in, but that feels a bit michael mouse, and it would always bug me. Plus, seeing one can still (relatively) easily get casings, I'm on the hunt for some good cases now. Good news though, i've got everything i need to do a bottom end rebuild on its way. So hopefully i can source some good cases soon and progress this revival!
  3. So yeah, found the problem why it was running so bad: /mitsi ain't that bad. But yeah, the crank side seal is chooched. Like zero crank compression, all comes out the side seal. Can hear it huffing out the side! I could just replace that i suppose? But the other seals are probably not far behind. So engine out it is! I'll get the cases blasted while i have them apart. So hopefully the motor will look awesome once its done. A bit of a shame the frame looks like this: Ah well, better strip it all the way down and get the frame blasted! Not bad for a quick carb rebuild eh! lol. Nothing is ever easy Also, here is the blue 1971 H1a drum front, back when i picked it up with @Beaver and @kicker back in 2015! It looks like a wreck, because it is. It is about 95% complete though. So if anyone knows of any parts, lemme know! As i'll hopefully be cracking into this later this year.
  4. Yeah, the H1s got progressivly "tamer" the longer the model ran, all sorts of regulation kept restricting them. The last of the line 1976 KH500 a8 is actually lams approved lol. A long way from the "widowmaker" reputation of the early drum front models! I've got a drum front one awaiting restoration. Currently accumulating bits for that. Anyway, back to this saga. First step, get it out of my room and onto the operating table. The dudes at bike night were more than happy to provide motivation support. So last time i had this running, the carbs were pissing out fuel, so took it apart and found that the floats had been eaten by whatever gas was in it. I managed to solder two of them up, but the third i had to pinch a float from my other h1 (1971 H1a) to get this running. I knew i needed to go through the carbs again and fit a new set of floats, and probably jets and needles too. The slides had seized from sitting. So off with the carbs and managed to get the slides out. I proceeded to whip the carbs off and take them apart to inspect: They were pretty clean inside, but one of the needle holders was loose as a goose. Looks like the securing brass pin had been eaten away. So will need to figure out how to re-pin this when the carbs go back together. The jets were pretty skodey (though not blocked) and the needle holders had seen better days. So will get new everything to biff in. I though i'd pull off the sidecovers to give them a bit of a cosmetic resto, Removing the stator cover, and about a thrid of a litre of two stroke oil came out.... this isn't good... You can kinda see the tide mark in the pics. This isnt looking good. It means that: a) The oil check valves are definitely tired/not working. So will get new springs and balls for those. They seem to be the rebuildable type, so thats a bonus. b) The crank seal on this side (and probably all the crank seals) are rooted, so that is probably one of the main reasons for its shitty running. Looks like i'll need to pull the engine out, split it, and get the crank rebuild. This will be a great oppertunity to get the engine cases blasted as they look a bit skungey. Cool, more work and $$. Thank god i love the misery. Should be finishing the Laverda, but that;s not a passion project, I love two strokes and Ducatis, The Laverda just looked like a good buy at the time (it wasn't) and i'm too far down the rabbit hole to bail now. hah Probably will need a new stator, and potentially ignition pickups too as god know how long they've been soaking in oil.
  5. Starting a thread for my blue smoke projects. God i love two strokes. Currently ripping into my 1973 H1 500. I bought this bike years ago (2015 i think). Went to look at it with @kicker and a deal was made. It was a US import that had been sitting in NZ for a few years. I got it complied and legal by the end of that year. Didn't even have my licence then! Never rode it. hah. Got the tins painted by @Bellicose on here. He did an amazing job. Has sat in my bedroom on display ever since. Started it up a few times at partys for lols. But never took it on the road. I did get a wof on it once. And rode it to an oldschool meet. But what a turd. It surged and bogged all over the place. I could also never get it to idle. It was actually pretty sketchy to ride with its surging and bogging. So parked it back up again on display. Until now....
  6. @toycollector10, where did you get your chroming done?
  7. yeah, rivets are just run of the mill, so how could they tell? Plus, its not like that vin wont match the frame/engine numbers too. Not doing anything dodgy
  8. If I want to repaint a motorcycle frame with a vin tag riveted on it, can I just drill rivets, remove tag, paint frame, and refit tag once frame is all tip top?
  9. Final test fit is success, fully clear dizzy cap and everything. Ideal. Next step, print the actual patterns to make molds from. Might start this week!
  10. Shit yeah, Can't wait to see what you do to it. What a score. Awesome there is no rust in the floors! Cut and polish makes it look ace!
  11. Is there a trick to doing it without pressing bearings on and off? That's my main concern. Was a mish to remove the old bearings off the shafts. Well one of them anyway, had to weld some nubs on to get a grip to get if off. Thats pretty much my only concern. Shimming and measuring will be fine. But if you need to do it when pressing bearings on and off then thats a real P.I.T.A.
  12. Oh shit, its almost been a year and a half. Well, I have everything I need to put the engine together and button it up. I'm just scared. Hah. I'm kinda a bit lost for how to check gearbox spacings and shim it all up etc. Need a working bee one weekend where everyone can give me terrible advice while I fuck up some Italian exotica.
  13. United at last: Final test fit of the latest design of manifolds. Looks good, except my womble self got the top flanges around the wrong way. Derp. Actual final print done waiting till i'm with the engine next for final test fit before is start getting ready to cast.
  14. @KKtrips No stress/rush. There are front seats, back seats, dash, trim, bumpers, radiator, roof racks etc. Can get some pics next time I'm out. If you'd like them closer to home I can bring em back with me one time. Also, so fucking rad this is legal dude. Super stoked for you! Has been no mean feat. Keen to do some bogan cruising with you!
  15. Still got those bits in masterton from that one we stripped. Need anything in particular?
  16. Sorry dude, just saw this now! Yep i can pickup and store in masterton for you. Will be outside though if thats all g. Pm me
  17. Where can one buy greensand from. Seems its easily available everywhere in the world except NZ. Typical.... I would love to have a crack at casting myself, just cos its something I've always wanted to do.
  18. The plan is to have a crack at backyard sand casting. I don't have the tools to do any lost foam casting, which is a bummer, as this seems to make the best quality parts. Sand casting also kinda determines the shape of the manifolds too, as they need to be split-able with no overhangs or inverse surfaces so they can be withdrawn from the sand. So created some patterns, and some core molds and printed them out (at 1.2% larger as from my research, this seems to be a decent number for aluminium shrinkage). Need to give them a good sand and some thick coats of paint to get them silky smooth. But they look like they should work? I have no idea what I'm doing now. Do I get them cast at a foundry? Is this expensive? Will they laugh at me? Or do I build my own LPG furnace? Or do I buy an electric aliexpress furnace? Then I have to mill and drill the castings... I don't have a mill. So yeah, maybe I should just buy some manifolds eh? Wish I could just print them out of something and roll that. Is that at all possible?
  19. And our wee drama with the rental trailer....
  20. So there are 2 things I need to get this v12 running again. 1 - Ignition. Hmm, after doing a bit of research, it looks like the HE v12 (the one i've got) runs a stand alone ignition system. The distributor has a hall effect sensor, and there is an ignition amplifier that acts as electronic points. This is Ideal. The dizzy has centrifugal advance and vacuum advance built in. No computers required. An added bonus is that the ignition is a standard GM affair (hidden in a lucas box) so they're 6 bux from rock auto! Should be easy and reliable. Excellent. I had a spare dizzy and set this up on the bench to switch a LED. Worked a charm and a mini rave ensued. The next thing I need is fuel. All XJSs were fuel injected. I had the fuel injection gear, but not a computer. My initial attempts with the XJS using a LINK LEM 3 were not very successfull, and felt out of character with a 70s car. I'm dead set on carbs! I don't car about economy, or chasing power, this car just needs to sound cool at WOT. The e-types and the early xj12s came with quad stromburgs. Although this was a proven setup, they are not renown for sounding wild. So that rules that out. Looks like its gonna have to be 6 downdraft webers! You can buy manifolds for them, but a set costing more than the series 1 donor car, I don't think so Tim. Being very inspired by @Roman rapid cad and fab stuff with his echo build, I wanted to learn fusion 360 and try and cad some up. Coupled with the fact that @DAD had lent me his 3d printer while he was tripping around the south island in his mobile palace, this meant i could do some cad and fab of my own! Some flange measurements, some frustrations, and plenty of hours in fusion 360 and i had something that bloody well looks like a manifold! I'll be dipped, It was actually fun AND rewarding! So I printed a "bank" for mockups: They didn't fit. hah. I'd based my measurements of a flange i'd found online. All the holes lined up perfect, but the head bolts in the middle fouled on the base flanges. So after a few tweaks, i finally had a base flange that sat down properly! oooh yeah. The engine is in Masterton, an hour and a half drive away, so I can't just do quick checks to avoid fuckups like this. Ah well, its all entertainment at the end of the day.
  21. So, I kinda ruined the xjs. 19 year old me didn't know what I was doing. Live and learn etc. However, 19 year old me still had some good thoughts. Manual v12! So previous me has spent a fair packet on all the spendy stuff and present day me has been left with a good condition v12, a good condition w57 gearbox, a lightweight alloy flywheel and a custom commodore/hilux hybrid clutch setup. Cool. Now I just need a good (more complete) car to put it in. Have been keeping my eyes out for a series 1 XJ6 for a couple of years now. But never pulled the trigger as they had always gone for way more than I wanted to pay. Plus my million other projects always were higher priority. Janurary this year, I spotted a tidy looking 1970 S1 on facebook down in Timaru. Went down to hang out the that vampire Kyteler and we had a look on the way back from the airport. It looked pretty decent, completely rust free, and reg on hold. Had the povo spec 2.8 in it, perfect as I'd be ripping it out anyways. The dude was really keen to sell it and kept messaging me for the next couple of days, I caved and lowballed him and he said yes. So we enlisted @vivaspeed's help, and did a school night mish up to Timaru to go and get it. The next couple of days, KY and myself tinkered with it to get it running and driving. Fuck she's a slug with the 2.8. Ah well, its not staying. We got it to drivable, but it had no park brake (the auto P) and no hand brake. Plus brakes were a bit spongy. Inboard rear makes it a PITA to work on. So it wasn't quite up to a WOF and a drive north. However, we did cut some laps of the block. It lived in Michael's shed for a few months until I could afford to ship it up north. Got it to Wellington and then drove it to my lockup in Masterton to await its transplant. Drove pretty well, though seriously underpowered. How cool is the dash on the series ones!
  22. Whaaat!? I put them up to 34ish with that gauge! They were all low too!. Must have been like 5psi in them before. hah.
  23. Hows the steering? Also, man this sounds tough IRL
