What do you mean by "high test"?

I run always run 93.

Again what's high test?

The cheap gas is what I've always used....my dealer told me high octane gas for a stock atv is just wasting your money.

Correct, If it's not pinging, your fine.
****, I run 93 octane in my other weekend toy that has around 575hp with 10.5-11:1 compression, when I just go for just a drive. Aluminum will et you get away with it.

typed this one wrong. sorry please delete ROB

boys i run a 70/30 split of 93/110 octane. love the little extra it gives me over the other 500's out there riding with us. lol

interesting, never heard of some one doing that before. hmmm

bowz

i run the cheapest, lowest that they have at the pump...here we ride up to the pump and fill 'er up.

89 octane here...summer and winter. The sparke plug shows no sign sof overheating or fouling...best of all no engine octane ping.

I run 93 in mine. Maybe it helps maybe not o well its only alittle more expensive.

I've heard several Honda techs say that high test brings your compression up too high. I ain't no expert, but 87 has been fine for me.

I run 93 in mine due to the fact that gas loses octane sitting in your tank over a period of time.

I grew up riding atv's since the first three wheeler days. Always put in the low end 87 and never had any issues. Some of these machines around here have over 50,000 Mi on 87 octane. Yes you read that correctly fifty thousand miles. Lot's of those miles are hauling fish in the sand towing boats etc. Tried higher octane av gas 100 low lead. And octane booster. Never made any difference in work performance, just the wallet lack of performance. However, if you where to put in a higher compression piston, say a 10.5 - 1 or higher You will see a benefit from it. The higher octane, just for lack of better words, keeps the gas more stable under the higher compression to keep it from predetonating. (PINGING)
As to whether it improves perfomance for you just try it out. I will stick with the 87 octane myself until I get my higher compression piston.
GL, Have fun. share your findings!

87 or higher is what the book says but I use high test usually.Had no pinging with any though.
