So I just picked up a used 05 sm the other day with kind of a lot of miles on it. (about 15,xxx) I got it for cheap and I heard as long as you keep the valves in check these things go forever. So basically I'm wondering what all I should inspect to make sure the bike is in good running condition. I do not want to start ordering parts and dumping $ into it if the motor is going to need a re-build soon. So below is a list I have going of things I want to inspect on the bike just for my own peace of mind. Let me know if you guys can think of anything I am missing. thanks! Check Valve clearance Flush/fill with new oil/coolant do a compression/leak down test Check the charging system anything else I want to be checking on a newly acquired used bike?? thanks in advance.
