hello!!!i need help,my honda nc700s won t start ,i changed the clutch plates and i got this problem.it s not the battery.when i try to start the bike i hear a noise in the engine like ''bum bum bum''

 

[670cc]

I don’t know what to say about the noise as it could be normal, but here is something to check. The crank position sensor that bolts to the inside of the clutch cover has been known to cause the engine to not run after work on the clutch. One or two forum members mistakenly installed the sensor upside down. In that position, to put it simply, the machine wont go.
