will 110+ octane leaded fuel hurt a '88 trx310R motor?

 

I find the best high octane gas to run is avgas. its a few bucks cheaper and its ok to use as long as its the Low lead Avgas...not the full lead jet fuel i get it at the local airport at 2$ a gallon @ 105 octane

 

I agree with surfer. I run the 100LL Avgas in my quad and never had a problem. Running 220lbs compression. Make sure you specifically get the 100LL(Low Lead)

leaded fuel will not hurt your motor, but always remember to run the least amount of octane your bike will tolerate without detonation. Higher octane burns slower and will go out your exhaust port if it doesn't completely burn by the time the port opens. Buy the 110 and mix 93 with it until dentonation and go back until it quits.Timeing will effect fuel requirments as well as combustion chamber squish bands.
