BTW, I'm running Castrol A747 (A caster oil) I get from the UK as "I Believe" it's un-available in North America.....Unless someone knows a suppier here. It's what I've always used in my 2smokes in the UK and swear by it. Mind you, with shipping it works out at nearly $50 per litre :x

The experts all agree running AV gas in powersports applications is a no-no. AV gas is very "dry" and doesnt have adequate lubrication properties like conventional race fuels such as VP, CAM II and Sunoco...
VP C12 or CAM II is the best all around race fuel for high comp. 2 strokes.

I run maxima Super M @ 40:1 with 100octane Avgas and have had zero problems. I have been running this since i purchased the bike new in 2000. My cylinder is still within spec. On my 3rd Piston and ring set. It's proof that what the experts say about avgas is wrong.

2 smoke ratio @ 100:1 :-o Jesus  F Christ!!!! I thought I was pushing it at 50:1 I wouldn't expect more than 15hrs on a piston at that..............but I could be wrong <gulp>

I've run season after season at the dunes and raced season after season in Whiplash with that and never had a problem. The only time I've ever had a problem was running Castor 927 - rings and power valves all gummed up. Yuk...

Alright Steve, looks like you're going to have a lot better choice of spares now you know its an 89 bike instead of an 86 as you had thought at first.
Also if you have a look in Gallery theres a few pages out of a steel framed 250 with 500 engine conversion that I scanned in and e-mailed to Alan, he bunged them in togallery to help me out as I am a numpty and was having problems :oops:

I can e-mail it to you if you can't find it there and would have mentioned it if I knew yours was an 89 bike.

Regards Scott.
