Rotorised:
Hey guys is anyone here running an alcoholic 500?  :-D I have just removed my head and would like to explore my options befor altering sqwish angle and head volume. I will hopefully be running a lectron 44mm, any specs would be much appreciated  :wink: . Are there any problems assosiated with running alcohol, I have read that it would use metho at 2-3times the rate of normal fuel?

stewart:
i spent weeks dyno testing my 44 lectron on achol  and found i could make as much or a little better power and same tourqe on oxgenated vp race gas

Rotorised:
That was my first choice, but after looking at a few fuel prices i found the vp race gas at about $5 a liter and methanol at about $1 a liter. In Australia anyway, If anyone knows of any cheaper prices in Perth it would be much appreciated

stewart:
it takes about 2.4 times as much alky so that raises the price per mile

Back in the 70's I ran my Montessa Capra 250 on pure Alcohol and caster bean oil. The bike smelled like a model airplane. I drill out the pilot jet to 3/16 and removed the main jet all together. I would just barely make one heat on 2 1/4 gal.  It ran cool and produced so much power, that on the starting line it would bottom out the rear shocks just revving it up. Back then we ran 250 and open in the same heats and would beat everyone to the first corner by 8 to 10 bike lengths.  I had a lot of nasty comments in the pits when I rode my model airplane by! He He!
