I would run the speedometer self diagnostics and see if the ECM has thrown a P0131 or a P0151 (lean front/rear) code. i had to ask for a longer bolt when i had to. So a Harley, especially one with a carb, is a lot more likely to have issues with detonation in hot weather. On pretty much ALL Harley's (and all other air cooled V-Twins), the rear cylinder runs hotter because the front cylinder tends to semi-block the airflow coming to it. If they wanted to monitor engine oil temperature they could easily have done that. apparently harley has used a bolt that does not go completely thru to hold it in place. Taking in account that the rear engine cylinders always running hotter because not receiving as much air flow as the front one, the “RCC” is conceived to try to equalize the difference of temperature by shutting off fuel and spark to the back cylinder if the motor idles for more than 3 seconds above 288°F. Why riding a Harley Davidson is different of which cylinder was on its compression stroke, with the other spark plug firing on its cylinder’s exhaust stroke. (the tailpipe begins to smoke in 30-90 seconds) Replaced the O-ring from carb-boot to cylinder head thinking a leak was the issue, but still happens.
