I recently bought a 01 cr250r and i ran preimum fuel with a 32:1 ratio and it ran great. I just bought 12 gallons of 107 octane race fuel and i mixed it 36:1. When i took it for a test ride the bottom end was spiting an spattering (alot of hesitation). But on the top end it ran decent. Do i need to change the spark plug or jetts in the carburator? Thanks
