Just having a look over the bike this afternoon. Pulled the plug and it was still very dark. I down jetted from a 168 main on Saturday night to a 162. Pulling the plug showed it to be well rich hence down on power 2nd race on Saturday. Dropping to a 162 obviously wasn't enough as the plug was still black I was advised with avgas the plug should be a grey brown. It just shows how altitude affects jetting. Looking at the plug I probably could have come down to mid 150's. The scoot survived the weekend quote well with minumn maintainance to do. I ve just been looking at the rear tyre leaning the bike over to see how far down I must be getting to shred the tyre the way it has.


It certinatly didn't feel like it was getting down that far. I also noticed the fiberglass airscoop also took a good scrapping. I'll have to modify it so it sits a little higher up.

The main modification though has got to be for more power

I'm just glad I didn't bin it and kept shinney side up !
