Alright guys, bought a 2009 CRF450 last weekend. Clean bike, good shape. Bike was cold, started a bit hard when I looked at it but ran great after words. Now that I have it home it pretty much seems to only start when it wants to. The plug is good, it seems to have enough spark. I am giving it the 2-3 slow kicks and then pulling the yellow knob and kicking it swiftly from TDC. Sometimes it will sputter after a coupe kicks, other times you can kick it 50 times and it won't do anything. It's strange because when you get the sputter like you think it's going to start then on the next few kicks it will go back to absolutely nothing, sounding like it's not evey trying to start. I can smell fuel but I am not sure if that is out of the ordinary for an EFI bike. I relocated the ground for the capacitor and have cleaned the connector for the IAT sensor and the sensor itself. I suspect maybe the kill switch? Once it gets running it runs alright far as I can tell and it starts fine when the motor is hot. Lets ASSUME (for now) that the timing is in spec and the valves are in spec. I will check them when I have time but full time studend, full time job... rare for me to get more than an hour in the garage at one shot. If I disconnect the kil switch will it elimiate the possibility of it being bad or will it not allow the bike to start at all? I am also planning on replacing the fuel filter. What else do you guys suggest for testing possible faulty components?
