What jetting are you running?Stock jetting?

No its not stock, I forget what I came to in the end. I ran it for about an hour before this trip and checked the plug it was just slightly rich with normal riding. I figure I could have leaned it out some but I didn't change anything as I would prefer to be a little rich on the sand.

What ever caused this, has to be a new condition. Like an air leak or exactly what everyone has said and I need to run a higher octane fuel. The local bike shop recommended me to run their JP-8 but I didn't for this last trip.

Odd thing is I did not notice anything different about the bike, it was running great, not running away like an air leak would. Just lack of power and then all of a sudden no compression. So I would believe either advanced timing causing too hot of spark. Or the low octane fuel.

I checked my Pipes Last night and the seem to be flowing fine with no blockage, so that can be marked off.

Edit: I guess it would also be possible that I got old gas from the station. I would find that unlikely but a possibility.
