Avgas and Premixing

[hondablade]

Has anyone ever had a bike running on Avgas before? If so, what type of premix oil do i need to be using and what ratio.

Im looking for a safe start point as i have a track day coming up and can adjust things if need be, just wanted to get some ideas from people with experience.

Ive been told by a bloke who does some club racing to run Castrol A747 with the avgas, but ive been on some forums and read some real horror stories about this stuff, (siezures and the like) and dont fancy that too much

Any input or ideas, links etc from you guys who might know about this would be much appreciated.

I used to use 50/50 Avgas and Shell Optimax, and for oil I used to premix in Silkolene Comp 2 (not the premix type) Is wasn't the more expensive and finer, Pro 2. I never had any trouble and used 33:1
