Raizer Posted August 19, 2020 Author Share Posted August 19, 2020 Zero progress has been made since my last A50 post, have had so much other shit to try sort out. So what is the best course of action to take when you have too many projects and too little time? Sell a few off? Nah get another one of course!! Thinking classic scrambler styling take on an adventure bike with this one, eventually. Something along those lines, but with lights and a decent pipe etc maybe. 8 Quote Link to comment Share on other sites More sharing options...

Raizer Posted August 23, 2020 Author Share Posted August 23, 2020 Not my fault, @Tumeke and @flyingbrick peer pressured me until I cracked... Took a 15 hour round trip to get them too ha Yeah, it's all their fault! 6 1 1 Quote Link to comment Share on other sites More sharing options...

H50S I'm thinking full 80s spec, few subtle custom touches, brown metallic and factory graphics reproduced. Or a new wave inspired paint scheme lol MB is the parts donor to start with, but thinking something like this eventually CB forks, CR80 gears to make it a 6 speed, Athena big bore and wild fluoro frame paint. 6 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted August 24, 2020 Author Share Posted August 24, 2020 Turns out the H100S isn't a S2 model like I thought, it's just an S, so it's got points rather than a CDI (had been told several times that the CDI was missing, guess they meant the coil lol). Added an A50 coil and got a nice strong spark and then discovered that the stuffed kickstart gears was just that there was a shim missing and the return spring hadn't been hooked on when someone had it apart in the past. Looking in the exhaust port the piston, rings and cylinder all look sweet, so squirted a bit of gas in the open intake and got flames out the port so once I clean and fit a carb it should be a runner! 6 Quote Link to comment Share on other sites More sharing options...

Bellicose Posted August 24, 2020 Share Posted August 24, 2020 I was doing that kinda stuff in oz in the early 90s. Done a f**k ton of old minitrucks and drag cars in that style. Long live the 'heartbeat' pinstripe, palm trees and checker boards lol. 8 Quote Link to comment Share on other sites More sharing options...

Will come have a chat some day once we get the tanks etc striped down for this and Sandy's A bike + we're back in level 1. Leaning towards brown on this one and letting you go nuts on the MB once that's on the go. 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted August 25, 2020 Author Share Posted August 25, 2020 H100S engine is in desperate need of a rebuild First thought was seize, but didn't really make sense as it didn't get warm or anything, still pulled the top end. Found it had a new base gasket, 2 loose head bolts and the washers from the other 2 were missing, lol yeah I'd say someone has been in here before! Piston isn't scored, rings look sweet, cylinder is pretty much mint besides needing a good bit of porting... Remembered it had been making a bit of a nasty noise inside the flywheel, maybe the issue is in there Lol fuck, the nut and washer were just floating around in the center of the flywheel, looking at the marks they have been jamming against the inside of the cover. But it was still locked up, dropped it into gear and giving the rear wheel a whack backwards turned the engine, but forwards again locked it in the same spot, so it's in the clutch side somewhere. And since I've discovered that the crank bearing on the flywheel side sounds abysmal and has enough play to let the magnets hit the stator I've called it for this engine, it can fuck off into storage. So now I'm cleaning the piston dust out of the MB's bearings and putting that bottom end into the H1 along with the 12v conversion and CDI etc. 7 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted August 27, 2020 Author Share Posted August 27, 2020 Stole the MB engine. Fucking hate working on filthy engines, so quick degrease and water blast Wanged the H100 top end over onto it, "fresh rebuild, no receipts bro" Went to throw it in today and, well, fuck. Honda being Honda just loves to fucking change stupid things between models/sub-models/years/what part of the world they are sold in/to fuck with me specifically. The 2 engines are 95% identical, only the MB came with CDI and the top engine mount is 20mm wider only on one side, why? Because Honda! Was going to just cut it, but that mount also has the breather in it, so if I cut 20mm off I'd open up 10mm of breather and loose too much strength. Smart thing to do would be throw this engine back into the MB and rebuild the original... Never said I was smart ha Just need to rob the CDI, Reg/Rect and the throttle/oil cable splitter from the MB, rig up some caps to delete battery and yeah it should go. 8 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted August 28, 2020 Author Share Posted August 28, 2020 Bit of very temporary CDI wiring Note at 8 seconds where I am reminded that a CDI kill wire is very spicy while the engine is running haha 3 2 Quote Link to comment Share on other sites More sharing options...

Raizer Posted September 14, 2020 Author Share Posted September 14, 2020 So much fun to ride, since there is zero low down torque, you have to give it a good twist of rabbit before slipping the clutch a little or it just dies, it pulls away fine, maybe a bit stronger than a stock one, then the pipe hits HARD and FAST and it just wants to rev and rev!! Got 80k at the top of 3rd on the way back down the street and it was only just feeling like it wanted to go up a gear But what I have been telling myself is just chatter from old clutch basket bushings is more likely the piston giving the head a bit of a kiss, so I'd better check squish and port timing and work out a plan from there, if I'm lucky the port timing will let me change to a thicker base gasket, if not the head will get a bit of a polish out. Edit: just tried to check squish, a piece of 1.6mm fluxcore solder locked it up solid, measured .47mm on second attempt. And that's not the squish measurement, just the max compression of the solder hahahaha 5 1 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted September 14, 2020 Share Posted September 14, 2020 That looks epic, especially for a 50cc. That compression ratio must be up there eh? Methanol next??? 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted September 14, 2020 Author Share Posted September 14, 2020 Methanol is deff something I want to try out someday, maybe not on this bike though lol Tried checking again with thinner solder .14mm is more than a touch tight! /Knew that anyway since the piston is tapping the head. 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted September 15, 2020 Author Share Posted September 15, 2020 OFF WITH HER HEAD! Pretty obviously been tapping away! Did a measure up, base gasket could really be .12mm thinner for perfect flow, need to get hold of some .75 copper sheet to make a head gasket from to space the combustion insert up. All in all, not too bad, could have gone real bad real fast at the RPM I was pulling yesterday! 8 Quote Link to comment Share on other sites More sharing options...
Popular Post Raizer Posted September 17, 2020 Author Popular Post Share Posted September 17, 2020 Genuine Suzuki base gasket I removed measured up at bang on .50, found a roll of .40 paper I had kicking about and squashed a bit and got this .50 - .12 = .38, couldn't have gone better if I'd planned it! Cut a gasket, then played with shimming the head to find exactly what thickness I needed gasket wise .75 was indeed about right giving a squish of bang on .65 Scrounged up an off-cut of copper, measures at .76 Spent a while marking out a gasket, took my time trimming it the best I could with snips Then promptly fucked it cutting the inside, attempt 2 or 3 went a lot better, not great but good enough for now. Next time I think I'll just bite the bullet and get one waterjet cut!! Test fit gave a squish of .67, I annealed the gasket with a MAPP torch, wanged it back on and torqued it up, checked squish and got .64, mint! Not so mint was dropping a nut while the head was off and it falling into the cylinder, the piston was at BDC so it went right down the exhaust port and is now in the expansion chamber ha. Oh yeah, and I finally measured up and ran the numbers 68.68cc of fury! 10 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted September 18, 2020 Share Posted September 18, 2020 Nice one, you did well there. Those squish numbers are much better now, definitely worth the effort to fix it. 1 Quote Link to comment Share on other sites More sharing options...
