I have a 1928 Deluxe. It has been rebuilt using new Ross
pistons, new valve guides, new valves, a hot rebuilt Simms
mag and a Zenith carb with the new idle mixture adjuster.
The timing is correct,valve adjustments are right on. Idle
mix is set according to Zenith instructions. I pressure
tested each cylinder as I installed the valve plugs, with
no leaks. The bike starts easily, idles smoothly and runs
well going down the road. My problem is that it runs hot.
After a quick 5 mile ride, the temp measured at the center
bolt hole varies from 360 F to 411 F taken with an infrared
thermometer. I welcome your advice.
