Kmp/h Had it to 94 the other day with the lean 165mj, reckon it'll do 100+ with enough fuel. It's fucking dodgy as over 70 though, rusted out wobbly front rim isn't doing it any favours lol. /Will easily do 100+ with a 16t front sprocket. Swapped in a 170mj and 17.5 pilot earlier and it's running a lot nicer. Keep meaning to send you pics of the old carb if you still want it. 1 Quote Link to comment Share on other sites More sharing options...

Raizer Posted April 13, 2018 Author Share Posted April 13, 2018 Chain seems to have grown a fair bit longer and the whole scooter wants to try and twist around to the left when starting to move. Think I might need a beefier swing arm haha Fuck. Lol. 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted May 25, 2018 Author Share Posted May 25, 2018 So yeah since last post I had it back in Auckland for a pest with @GuyWithAviators, @chris r and not @Shakotom as he had a work event... it ran like shit all, spent as much time trying to fix a fucked coil terminal that was arcing out than riding and then it developed a nasty rev cut out/limiter. The GC @chris r gave me a hand to rewire the coil, fixed it mostly but not the limiter issue, even changing the CDI, coil and plug didn't help... After my hang over cleared I realised it was throttle position related not RPM, so I pulled the carb off in the hotel carpark and discovered that the main jet had fallen out of the emulsion tube and was loose in the float bowl... Yep that'll do it. Next night @MopedNZ took Guywithaviators for a pest around Tauranga, my exhaust snapped near the start and I spent the night with a massive crack at the headpipe and it having the most power it had made, epic night. Got it home and left it in the shed till last week, with tomorrow's Auckland ride looming I figured I'd better fix the exhaust, so I zapped it up and went for a test ride, discovered it'd lost all mid range power Fuck. Decided it was the muffler restricting it even though it was very free flow, fucked around with jetting etc then decided wtf and remade the muffler core with less packing and no fluting to restrict flow and called it done. Didn't test ride, until last night I went to push it into the van and figured I'd better at least go down the road and see what it was like with the new muffler. Idled up to temp, first gear out the driveway felt good, on the road and into 2nd, ripped open the throttle and it spluttered, roared, lifted the front wheel then *POP* and it died, no compression at all. Fuck. Again. 3 1 3 Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted May 25, 2018 Share Posted May 25, 2018 I hit the like button. Not because I like that your head gasket is poop. But because you do good work and this is super unfortunate. 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted May 25, 2018 Author Share Posted May 25, 2018 At least it's not a holed piston or fried valve, looking at the bright side. Explains a few issues it's been having too, I actually think it's been leaking for a while tbh, grey carbon flecked oil was odd! 1 Quote Link to comment Share on other sites More sharing options...

cletus Posted May 25, 2018 Share Posted May 25, 2018 Being a new engine, it might benefit from re torquing the head after running it a couple of times? Or do you think its a tuning issue? Quote Link to comment Share on other sites More sharing options...

Or do you think its a tuning issue? I had torqued it to 10 or 11nm which is the stock setting, after talking with @BLIZZO it seems like bumping that up to maybe 15nm or more wouldn't be a bad idea with the high compression head and piston combo. Re-torquing wouldn't hurt either with China gaskets, looking at getting a copper gasket for it too. I'm thinking the ever growing head gasket leak was the main reason I've been struggling to get a consistent tune. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Raizer Posted May 26, 2018 Author Popular Post Share Posted May 26, 2018 Oh yeah, so after discovering the head gasket just hours before we were leaving for Auckland I refitted the factory gasket that I took out when fitting the high comp piston and head etc, torqued to just over 15nm and chucked it in the van more or less untested and with gas, carbon and chunks of gasket in the oil lol. Easily running the best it has since I've had it, think there's still a bit of power to be found though...
