Heating issue remains

i will have to think on this awhile :headscratch:

The radiator is designed to have air passing directly through it for proper heat rejection. Changing the angle or air flow pattern from the original location (meaning directly in the front on the 10 degree angle as on the bike) will reduce the amount of heat rejection achieved thus an increase in temp at the engine. The fan coming on when hot in traffic is common, but the temp level is a bit high. If you have access to an infra red thermal tester, you could check your actual in and out temps at the radiator, water pump and before and after the thermostat to see what temps they are actually running. It does sound like the fan/thermo switch is working.

I agree with mcgovern, not enough airflow.

If you read the 1200 overheating thread you'll see we went through 6 months of testing to find the cause.
One thing I found out was open airflow from the front to the radiator is very important to keep engine temps stable. Just the bulkier leading link front end is enough to affect temps. After I put air deflectors from a GL1000 on it the temps stabled right out and low on the gauge.
I think minimally you'll need to fabricate a scoop. I like the clean look it has now, cutting in a grill would kill it.

If you could build ram air ducts to pull air in over the radiator it would help.. ( and give another customized look slightly different froM the others..)
