Default Re: New engine. Clutch question:

in my experience, its completely normal for the engine to turn over with the plug removed and the clutch lever out. its because there is no compression. in fact, the easiest way to check for spark or compression is to remove the plug and roll the bike with the clutch out. to check for compression, put a thumb over the plug hole and roll the bike with the clutch out. if your thumb gets pushed out of the hole, you have compression. to check for spark, either put the plug against the head or put your thumb between the plug and head. roll the bike with the clutch out, and you will either see the spark, or feel a little zap if you have your thumb on it. it wont hurt.
