Hi Guys, My son's W reg 600n has been stood for a while while he's been trying to get a full licence. Last time I tried to start it, it was really rough, found out it wasn't firing on No3 cylinder. Stripped and cleaned the carb, blew it through with air-line (having recently done all 4 carbs), it was very reluctant to start, eventually fired up, still on 3 cyls, as it warmed, No3 came back to life, but bike wouldn't rev when the throttle was opened. As it warmed more, it would rev, but with a delayed action, both in spinning up and slowing down. After about half an hour of running, it started to run fine, gave it a run up and down the street, all was well! Except that after I turned the bike off and let it cool, when I started it again, it was mis-firing again, not as bad as at first, but still enough to make it hard to ride. I ran out of time but think it would have gone OK again if I let it get hot.
Any thoughts as to whats wrong would be much appreciated, Thanks
