i got a 2000 sp1
suddenly Bike has a hard start..i can hear the starting motor working..fuel pump prime..but just bike dont start...sometimes do and other do not.
i send injectors for ultrasonic clean..new sparks...check it on mechanic and coils working..has spark..
bike start at once if i push it and start in 2nd gear...bit with starter button start when she wants..
any idea please..
Let's assume your battery is good. Though the problem is almost certainly the battery.
If it is not the battery, you may want to clean out the starter motor. The brushes deposit carbon into the end bell and can cause ground faults. This increases the draw and decreases the starting torque. It's easy to take apart and clean.
