Coolant temps

Has anyone tried Wattman's coolant bypass yet?  Just noticed it the other day on his website.  Appears to work well on the KLR from what I gather.

   NOPE!  C10 cools fine just the way it is. Only problem I "ever" had was the fan switch quit working.
   OH!, and the radiator cap wore out after many yrs.

The bypass is not to cool the bike better, it is to regulate the engine temp better through a larger outside ambient temp range. Getting (and keeping) your engine at temp in cooler/cold weather will allow better mileage and drivability due to better fuel atomization and burning in the combustion chambers. If you understand metallurgy well you will also recognize the benefits due to reduced temperature stresses placed on the engine block and head when operated in cold weather.
This was a fantastic mod on my KLR and INCREASED my fuel mileage considerably in both cold and warmer weather.

This is one of the mods I did to my 2000 C10 and it worked great just as Matt said. Warmed up quicker and always had a steady temp gauge.

I took pics of my modified procedure on the C10 that was an improvement over the instructions that came with it. Let me know if you want it.

I did the thermo-bob too.  One nice thing is never having to open the OEM T-Stat housing again...    :38:

I figured while I was changing all the hoses anyway, to add the by-pass.  Works great, very happy with it.
Slight highway mileage improvement.
