lt1bird Posted November 15, 2014 Author Report Share Posted November 15, 2014 I build my own motors....they are unported just cleaned up....... since its in a streetbike, I want to keep the low end performance... Ill swap the carbs from my drag bike to this bike to make sure its not an issue with the new PWK carbs.... reeds are Vforce carbon...they still are new...no issues... some folks say they don't work well at lower rpm?

J-Madd Posted November 15, 2014 Report Share Posted November 15, 2014 The carbs may be too big, and not enough velocity?? Just a guess, but those seem big for a mild build that's trying to be street able (not WOT drag racing). Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted November 15, 2014 Report Share Posted November 15, 2014 Are you running Airstrikers? Quote Link to comment Share on other sites More sharing options...

lt1bird Posted November 16, 2014 Author Report Share Posted November 16, 2014 (edited) non air strikers.... in an aprilia rs250 chassis...bike with this motor in it weighs 280LBS... I am wondering if the carbs are too large as well,,,, but my 440 cub(non ported) street bike had the same carbs and it ran fine....but that bike was a lot heavier.... hmmmmm Edited November 16, 2014 by lt1bird Quote Link to comment Share on other sites More sharing options...
