I understand what you are saying. Can you tell me. What is the highest octane rating available at your local gas stations? Do they sell 100 octane unleaded? It should be a separate pump. If they do that may even be cheaper than the Aviation fuel. Possible even better results.He doesn't need race fuel right now and I'm sure he can't warrant the $13 a gallon. The av fuel is just for him to try an see if a higher quality controlled fuel suits his bikes needs.
