some87 Posted October 28, 2008 Report Posted October 28, 2008 what size jet should i go with an all stock shee with a k&n filter that was from 2.35k above sea level to 4k above sea level? Quote
dajogejr Posted October 28, 2008 Report Posted October 28, 2008 (edited) My rule of thumb...1 main jet size for every 1000 feet. Maybe 1/4 to 1/2 a turn on the air screw for 1000 feet. If it's spot on now, put one size leaner main in, turn the air screw 1/4 to 1/2 turn out, see how it likes it. When you start to get high in elevation, bumping up the compression and timing bring back some of that lost power as well. Edited October 28, 2008 by dajogejr Quote
some87 Posted October 28, 2008 Author Report Posted October 28, 2008 well thing is that i dont know how it should run when it was tuned since i got it out of my state. i ordered a jetting kit and it hasn't come in yet so should i try going lean one size? Quote
dajogejr Posted October 28, 2008 Report Posted October 28, 2008 Jet kits are a 100% total waste of time, in my opinion... There is a great jetting thread stickied to the top of the jetting and exhaust forum...read up!!! Quote
