Sounds pretty good...  although I think I'm hearing a few misses...
Steve's right,.. no response on the mix screw points to rich on the pilot...
...(mine don't respond to mix much either and I have a #50 pilot with a K/N filter...  we are up pretty high here in Tucson-at 2800ft)...

The popping sounds like an air leak in the exhaust...
Idle speed sounds good...

Don't idle longer than 10 minutes.... I'd keep it under 3... (it's air cooled, and it don't move a lot of oil at idle)...

Yeah, Im hearing the misses too. Also, there is a good chance it has an exhaust leak. The PO was a duct tape and JB Weld kind of mechanic(I think he must have gotten the JB Weld in bulk at Costco ) When I had the exhaust off to put the verslavy in it, I noticed at the exhaust port  what seems to be a large quantity of JB Weld on the head, underneath where the header pipe goes in; and the clamp for the pipe was mildly bent into a curved shape, but despite that, it all bolted on solid. Cant even imagine what the JB weld on the head is for, but due to the high mileage (51K) I have resigned myself to doing a top end sooner than later.

Tucson, huh? I am actually in Marana, but we like to think of it as North Tucson here


Gary, the two boots on either side of the carb are in excellent condition...I should know, because I have had the carb on and off enough lately Although compared to the Kawasaki KZ1000 I have also been having carb issues with, the carb on the Thumper is a walk in the park

Dave, you are probably correct. If that is the case, he must have succeeded, because it does not seem to be leaking. Will probably leave the correct fix for that when I do a top end, bigger fish to fry right now!
