i had a question im fairly good at th ejetting thing. especially with quads and whatnot, but i usually bump up the pilot jet or needle jet on those for cold starting and idle quality is better i was just curious if anyone has done this or just uses the stock 38 jet?? thanks. i noticed the f3's used a 40 pilot jet. thanks

 

there is a reason that the most respected performance tuning (dynojet) doesnt include pilot jets in their jet kits. they are not needed. 38 (stock) is fine.
