[QUOTE="jaguar, post: 721040, member: 19340"] With few jets available here and the fact that I like to mess with my engine (porting, timing, etc) I came up with the idea of an adjustable main jet and was able to successfully pull it off. I didn't mention it before because I wanted to make sure it was reliable. Well, after a year of use I can say it is. What is sweet about this is the quick adjustability for weather or altitude changes. If the bike isn't running right then just pull the carb and the bottom drain plug and adjust with needle nosed pliars. What I did is make the internal gas passage bigger by drilling it out some. Then I found a fine thread machine screw with a slightly bigger diameter than the gas passage. Then I drilled a hole for the screw at a 90 degree angle to the gas passage so that as the screw is turned in it blocks the gas passage more and more. Just thought I'd share this with you. So when it becomes available to the masses, you heard it here first! [/QUOTE]
