Im considering using race gas in my 2000 cr500 motor, but I really only want to do this if it will significantly reduce engine wear. The reason I ask is when I got the bike it had race gas in the tank, I ran it mostly out and switched to pump. The carb was still full of race gas, and when I rode it I was able to notice when it got to the pump gas. I noticed a little extra "engine noise" during deceleration, and maybe a tiny bit more vibration from the motor, and of course it no longer smelled like race gas. Now the first two were not major changes, in fact they were probably barely noticeable, but it was enough to make me wonder if race gas could reduce wear on things such as crank bearings, etc. I was kindof assuming that pump gas would be ok for a low tech big bore, but the motor did seem to run a little tighter with the race gas. Im asking because this is the closest thing Ive had to a brand new motor, and if using race gas would keep it that way significantly longer than using pump gas I might have to switch. Thanks!
