Good instinct Peter, I agree with you. Remember our bikes are aircooled, not oil cooled. There has to be a point of diminishing returns when blocking airflow to the top of the cylinder head with a large oil cooler.
Oil coolers shed heat when air is flowing, but not so well in stop and go traffic.
If you want to reduce your cylinder head temps, again, fatten up your mixtures.
Is this real?? dont you have problems with air flow to back of engine which could create a larger issue?
I thought our bikes were air and oil cooled
In stop and go I have had no issues
