My 2010 only has about 25 hours on it and has been a great bike. I am now riding a little more frequently (had knee surgery earlier this year) and getting more of a feel for it. Lately it has been starting up on the 2nd or 3rd kick when cold, but when the engine is hot it takes sometimes 10-15 kicks. Is this normal? Could this be indicative of valve wear issues? I haven't checked the valves yet; I probably ought to soon just to be safe.
