Air in fuel? Even one of the small injector jumpers letting air into the system will give exactly your symptoms.

The advance on the IP worked great ... today was cool and it started no CSV so I am happy. The engine smoothed out and power went up. I think come spring once the bike is on the road it is timing belt time plus all the seals. Man am I happy right now, starts great.
Good time had by all. Pun totally intended. Good to have success with such little effort. Not always the case with these buggers.
Ya I am trying to learn as much as I can .... I understand diesels but I don't understand these fully. Yes it can sometimes not be so easy.
