Shakotom Posted March 23, 2018 Share Posted March 23, 2018 On topic of ratios 15/35 on my chaly was 15/45 before - great for doing wheelies but not for speed Quote Link to comment Share on other sites More sharing options...
Raizer Posted March 25, 2018 Author Share Posted March 25, 2018 Been running about everywhere on this thing the last couple days, getting the tune a lot closer! Think I'm going to have to make a removable baffle for the pipe, it's louder than every other bike I've seen this weekend bar one open piped Vrod, don't think I'll be able to pass it off as a 49cc long ha! 5 Quote Link to comment Share on other sites More sharing options...
Muncie Posted March 25, 2018 Share Posted March 25, 2018 Stainless steel wool jammed in the muffler works a treat found pot scourers worked best on my Bonneville can hook em out with wire. Can fine tune it between power and noise they don't last forever but stops unwanted attention. 2 Quote Link to comment Share on other sites More sharing options...

Raizer Posted April 1, 2018 Author Share Posted April 1, 2018 Wasn't going to post this, but threw a couple little clips from the train station together. Phone speakers likely won't convey just how loud the little bitch is! 3 Quote Link to comment Share on other sites More sharing options...

Raizer Posted April 5, 2018 Author Share Posted April 5, 2018 So yeah I'm bored with it already. Hopefully this lot may help relieve the boredom Ported big valve high comp head with added squish band etc, balanced high comp piston with enlarged valve cut outs to suit the head. "easy start" CDI with switch-able adjustable rev limiter and a genuine Mikuni VM26 carb with adapter to suit my manifold. 3 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted April 5, 2018 Share Posted April 5, 2018 Your bike is badass!!! Question: Would the VM26 work on a 2-stroke...say a 180cc twin cylinder wajax motor for example??? I can make an adapter to fit, just not sure about if it's worth trying? Quote Link to comment Share on other sites More sharing options...

Yeah mate the VM26 can be set up for 2t easy, Mikuni sell 2t emulsion tubes for them. Another option for less $$ is the 24mm PWK I've got sitting here waiting for a good home, you've got a lathe so it can easily become any size up to 28mm... 1 Quote Link to comment Share on other sites More sharing options...

Would the size of the carb be in the ballpark? I've got a 19mm deulorto (spelling?)...but I've always thought it to be a little small, despite it running okay.

Raizer Posted April 5, 2018 Author Share Posted April 5, 2018 Yeah man, I'd be thinking 28mm should be a decent size for it tbh. 19mm is way too small imo 1 Quote Link to comment Share on other sites More sharing options...
peteretep Posted April 5, 2018 Share Posted April 5, 2018 oh man, I think the wajax had something like a 12mm carb on it, and i thought a 19mm carb was almost too big. LOL at 28mm being a good size Quote Link to comment Share on other sites More sharing options...
Raizer Posted April 5, 2018 Author Share Posted April 5, 2018 I'm running a 24mm on my 70+cc Gyro, it's about perfect sized for the engine. 12mm would have been such a restriction! Engine out, again. If I wound the idle hard in the carb wiggled into place, bit of hacking-I mean shaping- of the inner skin + grinding the adjustment screw right down small gave just enough clearance, 1 hole through the outer skin to let a screw driver through to adjust and it's done! SO MUCH COMPRESSION!!! I want to index the cam side cover so the "CDI" writing is level, there's a little tab that sits it where it is and this on the inside Can't see much reason I can't just put it on level? 3 Quote Link to comment Share on other sites More sharing options...
Raizer Posted April 6, 2018 Author Share Posted April 6, 2018 Took it for a ride, 155 main jet, 20 pilot, shit it hauls! Wheelies so damn easily it's a handful! Cracked the head pipe, that put an end to the ride. Running a bit lean up top with the 155 in it though, can hear and feel it's happier at 3/4 throttle than WOT. Chucked a 165mj in, should be pretty much spot on I'm thinking, will find out tomorrow. 5 Quote Link to comment Share on other sites More sharing options...
Raizer Posted April 7, 2018 Author Share Posted April 7, 2018 Set the tappets, chucked a new plug in and took it for a ride today. 165mj is pretty much spot on at WOT, has gained so much power right through the rev range with this top end, have to lean hard forward to keep the front down in second lol But after maybe 10 minutes running around it started developing a rather annoying misfire through the mid range FFS. 2 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted April 9, 2018 Author Share Posted April 9, 2018 Miss turned out to be a crappy loose fitting terminal on the coil earth, almost does hunnitz now! 165mj is a bit lean still (lol OOR said it'd be golden with a 140 and Mikuni said 155 max) Got a 170 to try, otherwise I'll order in 175 etc. The combo of a big cam engine with big carb jet + 2l petrol tank sucks!!! 1 Quote Link to comment Share on other sites More sharing options...
