jetting help

[DuneRaider]

okay my shee has 350 mains and 25 pilots, i started with the needle clip in the third position but that was way to lean so i moved the needle clip down to the number 5 spot, that helped but its still to lean,where do i go from here, the plugs are a tanish white color...thanks

when you say, "it's lean" that's pretty vague. are you saying after a plug run it's lean? or it feels lean in the throttle when riding? if you feel it in the throttle, what position of the throttle? if it's the plug color after a WOT plug run, then richen your mains.

its the plug color after a wot run

try some 360s and see if it's better.

what kind of cylinders aree you runnin that have 76mm pistons? or did you mean 66mm? who did your port job, they should be able to give a goo baseline to start at with jetting..

okay i think i got it, i ended up putting in 400 mains and the needle clip in the fourth position,the plugs are now a chocolate color, at low end the bike kinda cuts out a little and then it takes off like a freaken rocket, is there any way to clean up the low end?

back it off to 390s and see how it runs through the throttle. you also might try leaning the needle clip a tad by lowering the needle and see if that helps.
