give you slightly less power and empty your wallet more quickly. it's commonly accepted by engineers and performance tuners alike that you can run the lowest octane gas that doesn't cause knocking. for me this is about 89, though in hot weather with a full load i go to 91 so i get no knocking on uphills in 5th gear. my wife's xt225 has higher compression, so it requires 91 all the time to avoid the knock. -mark weaver

John,   I can remember a long time ago that some of the neighborhood motorheads would by gas from the local county airport which was very high octane (108-110), and very expensive, too.  I'd get a professional opinion on whether you should run anything higher than 103, though.   -Dave http://www.city-net.com/~davekle/ A8

Hi, Ah, memeories. Remember 115/145 octane aviation fuel for big recips (purple). Boy that WOULD turn your valves white, all that lead. Sheer waste too in a bike engine unless you are running, er memory...over 145 bmep, something like that anyway. Regards, Brian A14

Adding lead to gasoline was in fact a way to raise the octane or anti-knock rating. A higher octane gas will not add horsepower but it will help prevent detonation which will keep your engine much happier. Your friends engine did not "meltdown" simply because he/she used a higher octane fuel, in fact the hgher the octane the less likely a "meltdown" will occur. Perhaps there were other additives in the fuel that caused the problem or perhaps the fuel was not at fault at all. Ed Windsor Oh

Hi, I agree. Lead I believe was Tetra Ethel Lead (something like that) For a higher detonation level, therefore you could use a higher compression ratio. If you use methanol cr's were up around 20 I believe almost on diesel terms. Modern road fuels have all sorts of burn addatives, apart from anything els make it very hard to "read" a plug.

I was camping up at Mt, Pisgah on the Blue Ridge Parkway in NC last year and all I could hear was flatulent Harleys with illegal pipes ing up and down the parkway for miles. I was so pissed thatr if I had a rifle with me I might have made the evening news. If we ran pipes that loud around town we'd be pulled three times a day, but apparently "American Thunder" is more acceptable to la policia... -Tom '96 KLRT 650 w/ OEM exhaust system
