I just bought one and see that when it gets warmed up, it's exhaust header glows cherry red. Even when I get to riding it, the pipe stays the same red hot color. This worries me. Somebody tell me what to do. Will adding engine ice coolant help? I am also running 91 octane. Should I try to find the 95 that Yamaha reccomends? Is that glowing red hot effecting the engine, will it overheat, warp, and meltdown. Please let me know.
