noWheels Posted June 11, 2015 Report Share Posted June 11, 2015 Both myself and someone else have shearer in frames and his doesn't lag as bad as mine but just enough to notice. Thought it might be the pipes. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
bansheelapointe Posted June 11, 2015 Author Report Share Posted June 11, 2015 what is your jetting and do you have a cheetah with powervalves Quote Link to comment Share on other sites More sharing options...
bansheelapointe Posted June 11, 2015 Author Report Share Posted June 11, 2015 anyone who has a setup similar to mine can you please post info about jetting just for comparision Quote Link to comment Share on other sites More sharing options...
Coupelx Posted June 11, 2015 Report Share Posted June 11, 2015 Im running a ported 392 cheetah on 34pj carbs. 145 (i think) mains and 55 pilots. It needs more carb as its still rich even with the small mains in it. Love my cheetah, its got a wide smooth powerband. I hope to do some more tuning on the powervalves, maybe mess with springs in it. Like i mentioned before the best thing you can do is drill the bleed jets out to .125 (1/8 inch) its about the biggest you can reasonably go without getting into the thread. This is also the "lag" people experience and i think part of the problem with alot of cheetahs not "putting out". the valves cant react fast enough as the engine comes onto the pipe.

noWheels Posted June 11, 2015 Report Share Posted June 11, 2015 I have the same 421 setup as you but with mikuni vm36's. I had the pj's but they weren't enough. A friend of mine that I bought the top end from ran your carbs with it and liked them as far as know. I believe he had the same jetting.

shee4202 Posted June 12, 2015 Report Share Posted June 12, 2015 When I had my 421 p/v, I was running 152 (Main) and 50 (pilot). I believe a CEL needle. Clip position #3. I had trinity stage 4 exhaust, 35mm pwk's, Ran great. Quote Link to comment Share on other sites More sharing options...
Coupelx Posted June 12, 2015 Report Share Posted June 12, 2015 how did you like the trinity pipes? i have a set im gonna swap out with my R2's. rumor is they work well on the cheetahs despite the rather small stinger size. Quote Link to comment Share on other sites More sharing options...
shee4202 Posted June 12, 2015 Report Share Posted June 12, 2015 I've always thought they worked good. I think they sound pretty good too. I'm running them on a 485 p/v now and I don't do much more then trail riding, and they seem to do well in the low and mid range area. I'm going to try a buddies set of shear inframes maybe in a week or so and if possible my other buddies FMF Fatty's. Quote Link to comment Share on other sites More sharing options...
