I have been at this of and on for months.
I have a F2 an it ran like #$%*.
Only cylinders 2 and 3 ran properly. nr 1 would run iraticaly and nr 4 not at all.
NR 1 got spark and fuel. Finaly it turned out to be a float height problem. It was just to low so it would from time to time not reach the jet. If the bike run idle for 5-10 seconds it would reach the jet again and of it went. So after setting the floater correctly that was fixed.
NR 4 had spark but very weak. So I changed spark plug --> no change.
Checked the wires and CAP all OK. Hmmmm....This was more than a 6 pack problem.
Finaly after some good heavy beer I changed the CAP and yes it now runs like a rocket.
Apparantly the was a HT current leak in the CAP I was unable to detect with a Ohm meter. So at low voltage it checked OK.
