Hi, This is what I was scared of! Should have left it alone but maybe I will learn something ... just hope weekend riding isn't off. Took carb off, replace jets (main, pilot) - was running 420 - replaced with 400 (as per Pro Circuit since I have the PC pipe) - was running 40 - replaced with 37.5 (again as per PC). Generally cleaned carb pretty well - it was fairly clean anyway. DID not mess with the slide or needle. Measured float and made tiny adjustment to get into spec. Reassembled and it won't start for nothing! Used to start first kick. Plug is dry and kind of brown - replaced anyway just in case - won't start. Verified that fuel is getting from tank to carb. Please help - any advice will be greatly appreciated!
