Hey guys -some of you may have seen my other thread but I just bought this 73' Commando 850 - it seemed like it was running a little lean to me (a lot of throttle hang and some backfiring) and was idling at 1,300 hot so I took that down a bit to more like 1,100. The right pipe is making what (to me - an uneducated Norton fellow) an odd sound out of the left cylinder. I put a link to the video below. You can really hear it around 10 seconds in on. The other cylinder just pops right along fine. Any thoughts if that's out of the ordinary - sounds like a bit of a misfire to me. Bike runs great throughout the power band - like I said was a little lean at idle I believe - it was set up in October which is a good bit warmer here in Phoenix is my guess.
