Hello,
So my R1 is having a cooling problem, I removed the thermostat to make sure that this wasn’t the case. But sitting idle the bike will regulate its self both fans come on cools back down to where the fan goes off. Now while riding the fans come and the temp just keeps rising with fans on and just cruising at 80mph just climbs until the over heat light comes on. Then I just hit the kill button and let the fans run. Any ideas? I also looked to make sure my water pump is working when I start it to see the drop in the oil sight glass. Also while at idle the bike cools itself so idk.

Silly question but have you checked coolant levels?

Also, this should be in the 07-08 mechanical forum.

Is the radiator clean? I washed mine yesterday and was amazed by the amount of crap that came out.
