Wheres Bigbill? He loves octane questions!! LOL

I don't know if your rating is the same as ours over here. Maybe Bill can enlighten me on that point but I recently went to the mid grade here due to cost and have noticed no performance issues,no pinging or anything and mid grade here is 89 octane. I always ran 92 or 93 here until this year. Octane rating is the rating that indicates the fuels resistance to preignition that's why you need it in higher compression engines but our bikes are not high compression so it's not needed. You should need no carb changes if you run the next grade up.

I learned all I need to know about life by killing smart people and eating their brains.
