Thanks, I took it this afternoon to try it out after the jet change and it ran better but still feels sluggish in the lower rpms. I pulled the new plug after an hours riding time and it still looks really rich to me. I think I need to drop it another jet size. It has been many many years since I have messed with a 2 stroke so my memory is a little fuzzy on jetting them.
here are a couple of pics of the plug after an hour and a short video of it running. you can hear how soggy it is down low when you lug it.
Any advise tuning this thing for 5500' of altitude would be much appreciated.
