I traded a dirtbike for it and I was told it didnt start after he washed the bike, How true is that I dont know. But overall the bike's in great shape.New paint , powdered coated rims. It as a 907 motor in it. Ive seen the bike run and its great. IAm going to get it started and sell it for 2000. Any sugg?
1 Check the ground from the engine block to the battery. Clean the spot where it grounds to the engine and do not over torque the case bolt.
2 Have you tested for spark? Test for spark using each plug. I had 2 plugs go bad on me at one time. Oh hell replace the plugs anyway.
3 Set the petcock to prime with the tank over a bucket and see if fuel flows. if so set the petcock to prime when it is on the bike. If there is a filter in line check that it is flowing.
4 Pull out the black box located next to the battery tray disconnect it and check the terminals fo corrosion. If they have the green crap growing in there, clean them good with a wire brush be careful not to damage the plastic or metal. Then apply some dielectric grease to the terminals.
5 I dont know if your bike has this but under the battery tray near the rear shock there is a manual reset circuit breaker sort of a clear thing with a red dot. Push in on the red dot. If it clicks it may have been tripped.
Let me know if there are any other mods done to this bike.
Try this stuff and I'll see if anything else comes to mind.
I have tried all. Iam receiving spark from coil 1 and four. But not from 2&3. I took the cover off were the rotor his and it seemed to spark for a while then stopped. Iam checking spark from the plug against the motor. Any way of checking if it is the ignition on the motor? Or checking the coil or black box?
