High octane in any of the standard compression Chinese motors around here (99.9%+) is a waste of money for the low compression motor you've got.
More likely than not, since higher octane fuel needs a hotter combustion chamber to burn completely, you're just sending more fuel out the tailpipe.
If you're not already close to pinging, it won't prevent donation.
Even getting ethanol free gas doesn't make much of a difference, if you use the bike.
If it is going to sit more than like 2 months with 87 E5/10/15 ethanol in the tank, drain the carb and the tank, and put the fuel in your car, it won't have any problem with it unless you drive something +25 years old.
It might say 91 octane in the owner's manual, but that's RON, not R+M/2, which in this case most likely works out to 85-87 american.
