BeemerGee Posted March 7, 2007 Report Share Posted March 7, 2007 Hi, expertise help When is it the best time to change pilot jets, what mods affect it? How do you adjust carb to spark plug condition? Thanks Quote Link to comment Share on other sites More sharing options...
mpbanshee Posted March 7, 2007 Report Share Posted March 7, 2007 Anytime you alter the amount and speed of air moving through the motor (pipes, intake mods, porting, etc...), jetting adjustments are neessary. Some pipes like a fatter pilot, some dont. Your can "read" your plugs to see if your jetting is accurate. Do a search on here, and you will find hundreds of posts on how to read plugs.

locogato11283 Posted March 8, 2007 Report Share Posted March 8, 2007 generally only after you put pipes on it its a good idea to go to a 27.5 pilot..in stock carbs they come from the factory with 25. Quote Link to comment Share on other sites More sharing options...
Banchetta Posted March 8, 2007 Report Share Posted March 8, 2007 I find the more all around pipes don't need anything more than a stock pilot, but the more high rev pipes need 1 or 2 sizes larger. Porting will sometimes tend to want a larger pilot as well depending on the porting....Cold weather conditions will also require larger pilots and help the shee start a lot easier... as for plug reading. I run it wot in 6th gear for 5-10 seconds, kill it, coast to a stop, pull the plug and examine the ground strap...black is rich, dark brown is perfect, tan is lean....others will examine the inside porcelain, which to each and their own.
