[QUOTE="Matt Fisher, post: 891872, member: 30255"] First thing is to do a compression check (I just went through all this). At sea level you should be over 185psi. Next, pull the cylinder off, check the piston/cylinder/crank over, and thoroughly clean the powervalve. It should move easily and smoothly by hand. Once that's done you can think of possibly doing some jetting; that TMX carb sucks, btw. Jet needles are Suzuki specific, and backordered, and the needle jet is a non-replaceable item. [/QUOTE]
