rollback on startup

[sosot]

Has anyone had the maximum rebound when trying to start?? Mine has done this both cold and hot, and when it does, it sounds like the engine will break in half.
It acts like the time is too advanced, but I don't see how that's possible. The flywheel key is OK.. what else can I check?

Something is lost in the translation so I do not understand the question - can you explain a bit more?

Do you mean kick-back, i.e. it fires too early?

Is this a new problem or did it start after you had done something to the bike?

Are the plug lead at the front on the correct cylinder, are the cams set up correctly?

Sounds like he may be referring to the starter gear grind.

If your battery does not have good voltage ie not fully charged it will cause the starter clutch to “snap back” if your bike doesn’t start. One of the primary reasons for starter clutch failure
