I think you have a cooling problem, not a fuel problem. This high speed overheating characteristic has been observed with inadequate replacement radiators. If your radiator passes the flow test recommended by JacksonIII above, drain the radiator and measure the contents. If it measures less than 3 gallons you probably have a replacement radiator with fewer tubes than the original. It's okay around town and short tours but offers inadequate cooling for sustained high speeds. The solution is the find a good old stock radiator or get one re-cored (+- $700 in the northeast). We have seen the older repro radiators that held 2 1/4 gallons.
