hobbits are notorious for getting hot. I've seen people hit 500 and be OK, and other's who treat 450 as their upper limit. I try to keep it average under 400 and pull over if it gets to 420, which I've had DR's thatd do that on big climbs or whatever, but full speed there was enough air to cool down. Bigger head helps shed heat. Retarding timing pushes more of the heat out the pipe, bigger jetting is not a good solution bu very important to be sure you're not too lean and especially not airleaking. A bigger pipe helps dump heat out too, they're extra prone to overheat with the littler pipes like the jammy or worst if you tried to use a kit with stock exhaust.
