Default Re: Brand new to gas bikes.

This subject has been discussed several times before. I too at first didn't want to believe 87 could be better in low compression engines than 93. So I did lots of research and found the detonation point is lower in 87 than 93. After the research I was willing to come back on here and admit I was wrong. I now run 87 in my 4 stroke engine and it does perform better. I'm also fortunate to be able to run 100% gas in my hometown. But from all the research I've done it said any compression below 9.1:1 use 87.
