95prerunner Posted December 3, 2003 Report Posted December 3, 2003 my local yamaha dealer sold me some pro-tec performance jets. The kit came with some shorter then normal needles and some big jets 390,400,410's. The instruction say with pipes and K&N, no air box cover to run the 400's with stock pilot. My stock pilot is 25. My mods include coolhead 21cc domes, .050 overbore, carbon tech reeds, ported stock reed cage,fmf fattys with stock silencers. Does anyone know anything about the pro-tec jets they seem really big to me. Quote
