O/T - Motorcycle runs rough - basic engine ?
I know its not a Jeep but it has as many cylinders as some. Its a '74 Honda CB550 with an inline 4 SOHC. Today I was riding it when all of a sudden it felt like the power nearly doubled. It had always ridden kinda flat and all of a sudden BAM... I had power. But at the same time blue smoke started pouring out the right pipe. So I know its a problem with cyl. 3 or 4. The left side had always burned a little oil but not like this was. It rode good for a little while and then it started getting jumpy. With a steady control on the throttle it would zoom and then slow down. I can clearly hear the 1 and 2 cyl. firing through the exhaust but the 3 and 4 exhaust is almost dead quiet at times. I don't know quite what to think broke. At first my guess was that some crud was cleared out of the carbs and it was finally running right. But with it running the way it is I'm not so sure. Any ideas?
