Hawkwind: I have used methanol on a carbureted air-cooled M/C at Bonneville. I switched from petrol because I was having problems overheating about 3 miles down the course. You need compression and timing to run at 4200' and methanol was the only way I could cool the engine. After first boring all the jets to twice the AREA of the petrol jets and milking the oil almost instantly I found that just the mains needed to be enlarged. I could safely get 6 four mile runs before the sight window started to look whitish. I used petroleum oil and never had any bearing problems although the starter sprag came loose a few times. I also had NO2 on the bike but never used it. Probably should have as my best mile was 199.8 Good luck with your project. Larry
