OK, so now I'm running out of ideas. I bought my F1 last year as a basket case, but most of the frame and fittings had been sorted and the engine was complete, so I thought it was just going to be a case of bolting it all together. First thing I find is that I have an F2 engine - no problem I thought, bit more grunt. After much effort, finally got most things together and then try to start her. No matter what I tried, it had a massive bogging down problem, would tickover OK, but as soon as the throttle was opened, it would almost die. On full choke, I could just about get the revs up, but that was all.
Spent some time playing with timing and checking everything, then I found the Carbs were off the original F1 engine - Ahah, I thought, there's me problem. I rummage around in the boxes of spares I got with the bike and find a set of F2 carbs, so

G,Day Barty,I would be looking at the ignition if i were you, it sounds to me if it is not advancing up as the revs increase. IF the engine had points ignition originally, re-fit them an give them a go to eliminate the electronic ig.Also, mufflers are not blocked are they?
Cheers,PABLO
