Any one here run race fuel in their bikes. I bought 5 gallons of it. Just couldn't help my self. I don't expect it to make my bike go 100mph or pop wheelies in all 4 gears, but do expect a slight performance change. I'm told it runs much richer than normal gas. Its a high octane high lead. Any one got a clue as to how much leaner I should run it. I'm using a 122 main in a p200 right now.

I've been running a mix of 4 gallons of ethanol free plus 1 gallon of Turbo Blue in both of my Ps. I can tell a difference in the way they rev and pull, and the old P is much easier to start when cold. It used to fire when cold on the sixth kick and now starts on the second. I wouldn't run straight race fuel if you're running a stock engine, kind of a waste. Also be sure that what you've bought isn't oxygenated as this can screw with your jetting and foul your carb and fuel system if it stays in the bike for a while. We had issues several years back running VP U4-2 in a bike that I raced GNCC.

C12 is non oxygenated and is rated for both modified and stock engines. mixing it kind of maxes since. would definitely be cheaper than buying octane booster. Did you have to lean your carb out any?

nope, bike runs amazing. No pinging and the plug looks good. The Turbo Blue runs about $8 a gallon, so goes a long way.

Ive used 100LL AVGAS in my hopped up P200 before. I'm running an Alpha tuned top end and Vortex carb from Hot Rod Scooters with a Boom Stick. I saw a slight increase in power and performance. Probably the biggest difference I noticed was how the exhaust smelled. Very clean, almost sweet. It was more of a novelty than anything, I didn't run it long enough to notice any changes in mixture.

I've been considering this as an option also.

I ran through about 5 gallons of the c12 and never bought anymore. I could lean the motor a few points with no adverse affect. There was a noticeable increase in power, and a proportional decrease to my bank account. Plus you can't get it at the pump which means if you run out you have to rejet when away from home.

apparently a few stations in my part town carry 110 octane, lot of gear heads around the PNW. I'll try it for fun next paycheck, without doing anything else.
