I did my first race of the season this weekend, and I had some over heating issues.
Last season I knew something was not right when at the end of a race I would have radiator water on the side of my engine, but this was the first time it got serious.
Here's the dish.
Standard OEM radiator running distilled water, and water wetter.
OEM overflow bottle.
The bottle vent is routed to the rear of my bike into the catch can, and that vents to atmosphere.
When the radiator would boil over it would fill the overflow bottle, and the catch can, then lubricate the underside of my bike.
After one instance of over heating I drained the system, and put straight distilled water in, ran the engine, then drained. It came out crystal clear.
So the question is why is it overheating?
One person had suggested the thermostat.
Is it possible to remove the thermostat altogether, yet keep the temp gauge?
This is a race bike and I want it to run full bore all the time anyway.
Another possibility is the water pump, but that is a simple mechanism, and if it was bad wouldn't I hear it?
OK what do you EX experts think?
