SICK BOY Posted January 8, 2004 Report Share Posted January 8, 2004 I'm just finishing putting my shee back together from a complete rebuild and have a jetting ?.I have replaced the stock carbs with 28mm flat slides and was wondering what I should start my jetting at?My mods are listed below in my sig. and my elevation is just above 700'.

flea49 Posted January 8, 2004 Report Share Posted January 8, 2004 YOU DID NOT SAY THE MAKER OF THE CARBS,BUT IF THEY ARE PWK,I WOULD SAY 160 MAIN AND 42 SLOW. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted January 8, 2004 Report Share Posted January 8, 2004 Mikuni, I'd say 340's since it's cold, 27.5 pilot (very cheap for these carbs) and needle in 3rd (stock) position. Make sure you use the needle that came with the carbs. Quote Link to comment Share on other sites More sharing options...
Aussie Quad Racer Posted January 8, 2004 Report Share Posted January 8, 2004 if they are mikuni i wouls suggest starting out with a couple of sizes up on the main from what you had in the 26mm carbs. The other question is are they power jet carbs? Quote Link to comment Share on other sites More sharing options...
SICK BOY Posted January 9, 2004 Author Report Share Posted January 9, 2004 They are Mikuni,and they are not power jet.I don't plan on riding intill spring,so do you guys think 27.5 pilots and 360 mains would be alright for spring/summer?

fixitrod Posted January 9, 2004 Report Share Posted January 9, 2004 In the sring, I'd start with 330 or 320's. The warmer it its, the smaller you go. The air is less dense. This is a starting point of course. Quote Link to comment Share on other sites More sharing options...
SICK BOY Posted January 9, 2004 Author Report Share Posted January 9, 2004 Thanks fixitrod,I had the process backwards. Quote Link to comment Share on other sites More sharing options...
Yaxy Posted January 10, 2004 Report Share Posted January 10, 2004 In central NY (Utica area) where I am from (800 - 1200ft assumption where I ride) I use 20 pilots and 280 mains on the 28 flatslides with the air box lid on and 4 1/2 inch holes. At one time I did run 15 pilots when I had the pro-design intake but had to go up to a 20 when removed. Every machine is different so make small incremetneal changes ideally at your ideal riding temeperature and atltitude. PS. It never hurts to be a little on the rich side.
