All is well!
Plugged / restricted exhaust. Neighbor pulled me down the driveway and it built up some pressure enough to push some chunks of carbon out and she fired right up and ran just as well as it has been(with the light switch on). When I got back to the house, after a small ride, I free revved it a couple of times (which I never do) and a whole bunch more pieces where spraying out on the driveway. I need to get this pipe serviced! A month ago I was in there chipping away at that 6 year old **** and did not do a thorough enough job and now some larger chunks that I have disturbed are finding there way free and plugging up the small passage way after that huge cone and before the silencer. I have always payed attention to the carbon in the front of the pipe but never have really given much thought about a carbon problem all the way back at the rear! It really is a difficult task for me to try and get in there and get that stuff out. It sure did cause me a lot of grief last week, but I think it was a reminder, or a lesson for me, that friends and family and religion, are more important than that old carboned-up non-running Zilla in the garage. Yea right.

Big hill climbing ride tomorrow. I am loaded up and ready to go. 16 hours to spare!

I would appreciate very much any thoughts on carbon build up.
