Just remember that, young man 🤣🤣🤣

Isn't a CF Moto a Chinese machine? I had Chinese made UTV years ago (lost it in the divorce) that had a CF Moto engine. This was a much smaller UTV, but it was impressive. I believe it was a BMS. That thing carried me and my brother in law up some really steep hills during deer season, and through some really wet stuff. Had a hydraulic dump bed, too. It was carbureted, with a manual choke. That was the only thing I didn't like about it. It came from Texas like the Massimo did. I don't see them anymore.

As I said. Compression does not dictate octane. Go with the manufacturer recommended fuel or use standard 87 and add octane booster. Same same

lol I guess so.. now it makes me watch a freaking 30 sec ad before I can use the forum?? WTF!! Doing great, buddy.. Had my back surgery, feeling like a kid again! How bout you? Everything going well? My MSU 500 / Hybrid Yamaha still banging along , no issues and my new CF-Moto 600 is a bad azz machine.. I am smokin Hondas and Arctic Cats on flat ground and in the mud!

I do own a Massimo and owners manual says 10:1 compression [ I did not tear it down and measure components] and it recommends 91 octane or higher .. but you probably know more than they do. no one suggested he would get more power from 91 octane but I do suggest he can detonate enough to destroy a piston with insufficient octane.. If it could run just fine on 87 , HISSUN and Linhae would recommend it . just my 2 cents worth

You'll get all kinds of opinions. Just remember they are uninformed opinions because none of these people will know the specifics of the engine design. Required octane isn't based purely on static compression ratio. There are many factors such as valve timing and piston shape . The only thing higher octane provides is the ability to compress the fuel more without pre detonation. It doesn't improve power. Go with the manufacturer recommend fuel. They designed the engine. If you can't get that fuel, use 87 and add an octane boosting additive. Cheaper than unobtainable fuel and just as effective. There's absolutely no good reason or benefits to run 93 octane in these engines

Will do, thanks 👍
