I've done a search on jet kits, and it seems that all companies(I.E dynojet, factory) isn't any better than that of the stock honda needle/jetting. I've installed a kn&n (kept snorkle), and a slip on high mount. I noticed a hesitation all around throttle response, so I installed .01" larger spacer (from OSH) and adjusted the mixture screw 2.25 turns out. I am about 0-100 feet sea level.... But besides all the detail, I am still feeling slight hesitation with the throttle. Is this normal? Sometimes it feels like a two stroke in the turns where I'm punching it. Oh yeah, I've also cleaned out all the jets/bowl/carb. Thanks!
I would like to offer up a suggestion....Give Wheelsmith Racing (in house tuning arm of factory pro) and talk to those guys they have a very large amount of tuning and jetting experience, they can separate the bs from the real deal.
