WALLACE84 Posted March 6, 2008 Report Posted March 6, 2008 Do you have porting too? Im running 35 pwks with powerjetts on my drag ported 4 mill Quote
jbooker82 Posted March 6, 2008 Report Posted March 6, 2008 In my oppinion Drag port PWK 35's. Dune port PWK 33's. Quote
2001Stroker Posted March 6, 2008 Report Posted March 6, 2008 I've got 35's on mine. Had to jet it up a little to get it running perfect. But I do have 18cc domes. Quote
Bansh-eman Posted March 6, 2008 Report Posted March 6, 2008 what kind of pipes? performance pipes donest mean much, also what porting do you have? Quote
twinrock Posted March 6, 2008 Author Report Posted March 6, 2008 well the chambers are hand made by a pro pipe builder this is not in a quad ..but a road motor cycle http://s36.photobucket.com/albums/e47/twin...ent=mito006.jpg what kind of pipes? performance pipes donest mean much, also what porting do you have?

rubberneck Posted March 7, 2008 Report Posted March 7, 2008 Nice bike man. From what I have seen on here, most people would say 35s if it has a very aggressive port job otherwise stick to the 33mm. I dont know anything about that cylinder, on a 4mil x 68 cub, jeff at fast had me go with 39mm carbs because they flow a lot. Quote

twinrock Posted March 8, 2008 Author Report Posted March 8, 2008 peek power is designed for around 9500-10000 rpm... do you happen to know where the pipe is designed to make its most power at? this would help you figure out what carb would be best suited for you. its more then likely a 35 Quote
GASSRX Posted March 9, 2008 Report Posted March 9, 2008 35mm for cpi work well how did the porting and what drag,trail,mx Quote
Animalman294 Posted March 29, 2008 Report Posted March 29, 2008 Ya, I think with my cubby I am going to stick with the 35's and get a set of shearers. I'm not sure if I would be gaining that much to get a new set of carbs like going to a set of 38's........... Quote
njbanshee Posted March 30, 2008 Report Posted March 30, 2008 I had 33's with a 4 mill stroker ported, then went to 4mil stroker cubs drag ported and my builder said 39's. Quote
RadarRacing Posted March 30, 2008 Report Posted March 30, 2008 Sweet bike. I know lots of guys that run 33s to 39s with topend pipes,porting. I'd say if that's a bike for carving curves I'd stick a little smaller like 33/35 but if it's a bike you ride wide open a lot or drag a bunch then go 38/39. I know some seriously fast 421s and one of the fastest 7 mil cubs I know of with 35mm carbs. I like the snap and throttle response of the smaller carbs. Quote
Animalman294 Posted April 4, 2008 Report Posted April 4, 2008 Ya, I shoot the hill, but dune carve mostly thats why I am going to try the shearer's then think about the carbs............ Quote
