Overheating

Hi Guys I went for my first proper ride on my new XR this weekend, and in the slow technical stuff that I enjoy the bike showed 100DegC very quickly. I did not hear or see it boill, but the Vapor Trail Tech computer showed the temp. Should I take the thermostat out? I am at sea level, and I would really apreciate some help.

Thanks

Listen, there is only one thing you have to do:
Get some Evans coolant. That's it. You might also move to a better thermostat. But mainly just change to Evans and follow exactly the instructions. There can't be any water left in your system when you install it. Evans doesn't boil so there's no need for any high pressure caps or any of that stuff. That is the wrong way to go. That system was not designed to be pressurized much so increasing the pressure is asking for trouble.
Post to the Yahoo Group to confirm but it's what all the racers here in the deserts of California do. Or simply search the yahoo Group for "evans".

Let me know if you need help getting it.

I found that my thermostat was jammed nearly open which is a common failure caused by the pin bending. This was replaced with the Suzuki swift thermostat and it has since been OK even in deep bogs. Worth a look to start with but UK temp are usually low so yours may be something different.

My stat was also jammed all the way open, I replaced mine with one from xrsonly, works like a champ. I also have the stock radiator cap. Everything works great on tight technical stuff up to timberline.
