Hello, I just bought a yamaha diversion xj600 1992. I have the following problem (or not!). There is a slight kicking sound when I start the engine. I googled that and I found that two cylinders might not work. Also, and that might be related, at low rpm (2-3000), the engine power has some fluctuations... Other than that it runs well. How can I find out if there is indeed a problem? how bad is to ride it like that? and is that a hard and expensive thing to fix?
Thank you
