I just bought this bike. It appears to be in great shape. I had the same bike about 13 years ago. I was bikeless for a while. Then I had an ultra slow, heavily modded '09 KLR. It never made me smile so I launched it. I have done nothing to this bike yet. It needs the air filter cleaned, maybe a new spark plug and some tune ups including the bog sticky among other things such as a clutch cable. Granted it warmed up to 31 degrees so maybe everything was tight. Oh, the gas isn't fresh smelling either. I don't know the rpms but it wasn't ripping like it should. I'm far from a technical motor guy but have friends that are. Any suggestions besides what I've mentioned here?
