Here is what I have, My bike is hard to start cold but once it's a little warm it fires first kick every time. My problem is that after roughly 45 minutes of riding the left cylinder stops firing at idle. This happens every time I ride it for 45 minutes or longer. It also sometimes but not always revs up(only right cylinder firing ) about 1000 rpms during this time. This is what I have done so far. new float needles(gas was coming out of the over flow tubes) checked float hieght cleaned carbs, resynced carbs(using the sight windows) sprayed carb cleaner around carbs looking for air leak, new plugs, fresh gas, checked comp (108left 110 right) With engine warm and throttle open. I have verified choke tube is in, float bowls are on the correct carbs and so on. I also tried switching switching plug wires and plugs with no luck. The torres thing is still on the carb but all wires are disconnected and the torres control box is removed from the bike. I have a Mr Gasket temp gauge in the radiator cap and it never gets above 190. I get a little water dribbling out the over flow hose every time I ride.
