[QUOTE="Ol'89r, post: 1407383, member: 17212"] Matt is correct. If the bike won't idle, the first thing you should have done is clean your carb. I tend to dissagree on the compression check though. While a leak-down test is a better way to determine the condition of your engine, a compression test is a quick and easy way to get a base-line reading. If your compression is low you can add oil to the cylinder. If the compression rises with the oil in the cylinder, it indicates bad rings. If the compression does not rise with the addition of the oil, you have bad valves. Not everyone has the tools necessary to do a leak-down test. [/QUOTE]
