'05 TW. I managed to lose the small spring that sites on top of the carb needle and under the small white plastic cap. I wouldn't mind buying a carb rebuild kit to get a new spring but it isn't clear from the kit descriptions that this spring is included in any of them. Anyone know if the carb rebuild kits include this spring or know of any substitute? Reason I took carb off is the bike has an FMF power core and it runs really lean and hot at higher speeds. Spark plug grey, pops on decel. I drilled the main jet with a 1/16" drill which was the smallest drill bit I had and bought some washers to shim the needle a little - I couldn't find 2.5mm washers locally in stainless, only 3mm stainless and 2.5mm for zinc. Any opinion regarding using the 3mm washers which are only a little loose vs the 2.5mm zinc ones? I did order a 130 main jet but it won't come in until mid next week which is why I drilled the stock 126. I also removed the cap over the enriching (?) screw which was only 3/4 turn out and backed it to 2.5 turns out. Carb was pretty clean but I am soaking in Pinesol.
