octane booster

[2004exrider]

hey just wondering if you guys use octane booster in your quads, is it good or not worth it. is there anything bad about it that should be known. would it be safe to use in a 400 that still has stock piston.

It's a waste of money, doesn't do anything...:o
Just run plain 89 regular in your quad if the motor is stock, it will make the most power this way.

a guy i ride with used some high dollar brand of octane booster in his new z400 and all it did was foul out his plug. dont waste your money
