Hey all, As my handle shows I'm riding a '99 WR400F. I live and work in an aviation town where my access to 100 low-lead (not UNLEADED, just low-lead) aviation gasoline is fairly easy. Is it OK to run non-unleaded fuel in this bike, and will it result in slightly lower operating temps with the higher octane? Is that high an octane and the fact that its not unleaded, any cause for concern? Any advice or insight would be appreciated!
