    Stock R's compression ratio is only 8:1. Racing gas Above 93 octane will cause these bikes to run really rich, even jetting changes will not be worth the extra money for race gas. I can jet with the best of them and noticed decreased performance with race gas in stock 85 ' 86 250r's
    92 or 93 pump gas and rejet 2x a day sometimes and you will be a happy man!!! 1 move up or down on the needle clip is like night and day!!!!

    I don't think anyone realizes the the octane levels in fuel have dropped about 13-16 points over the last 30 years. At one point in time 100 octane was regular fuel. De-Leading the fuel made the significant drop to todays fuels.

    my uncle still dumps mothballs in his tank from time to time. i'm kinda curious as to what this octane boost will do.

    pirogue, just go to that loves on 415 and get your premium. make sure to go to pump ten...as it's noticably faster than the others. lol.
