2 cylinders not firing?

#1 Unread post by skidz »

I have an '81 750C. Just pulled 'er outta the garage for a run today and well, didn't think I'd make it home. Started right up and sounded fairly good for being a bit chilly out this morning. Anyway, had very little power and when I got home I noticed the exhaust on the right side (both pipes) were wet at the back. Pulled and cleaned all the plugs and arced the wires for spark and they all seem to be firing. Both cylinders seem fine on the other side of the motor.

Just put gas in it and changed the oil yesterday. Everything is fresh on the inside. Any thoughts?

Most bikes Fire cyls 1/4 and 2/3 at the same time ... If you're not getting power on the two right cyls, the prob may not be electrical, unless you have some wires crossed (Meaning you have a cylinder or two off-time)

I had the same problem on a 84 VF750 and it was a loose electrical connection. 2 cylinders would kick on and off at random times.
