Hallo! I got the bike going somehow on all 3, and drove appr. 60 miles yesterday. But...the left cylinder works only when I´m driving with max. 1/4 of full throttle. Anything above that and it dies instantly. I have doublechecked ignition timing + carburettors (needle position, float level etc.), tried different new plugs(B7ES,B8ES,B7EV) (engine is just bored and it has newtronics ignition). Could it be ign. pole or those seals in crank between chambers? And another thing: it´s quite difficult to start when warm. When engine is cold, it starts on first or second kick, but when it`s warm, it takes about 10-15 kicks to get it going. Can these things have something to do with each other? Thanks, Harri
