125,000 with no problems...but id still like a way to get heat away from it...but it probably won;t happy with out reclocation from the head.
being so close to the engine theres no good way to get the heat away form hit....Oh and a KKM is properly efective with a heat sheild.....with out that, you would be just sucking in hot air,(heat soak) which can cause low end performance loss. High end you do not need to worrie as much becuase your getting the flowing air while in motion.
