A couple of weeks ago I purchased a new 2009 klr 650. The dealer started it and test rode before I picked it up. When I got there it started right up. Trailered the bike 3 hours home and it refused to start, cranked on it till battery was almost dead and it finally started. replaced the spark plug, bike sat a couple of days and same thing. Tried it again today still did not want to start. Once the engine is warm it starts easy. I checked the compression on a warm engine and am only getting about 40 psi. When it is idling you can hear a ticking noise in the motor.
