Has anyone actually fitted temp gauge and proven that their bike overcools?
Maybe on long, slow highway rides the temp would drop too much but I ride mine hard on road and track and it always feels well up to temp. I can tell if it's cold because it runs too rich at off idle until it's up to temp. Once it's hot it never cools back down and goes rich again.
If it aint broke leave it the hell alone.
Engines run lean when they are cold, not rich!!!
I dont think you really understand the issue
Bikes with rads big enough to cool at 15-20mph in first and second gear will overcool when driven at 50/70mph in the higher gears unless a thermostat is fitted to restrict the water flow and regulate the wayer temp
The fact I used to get white emulsified oil in the breather pipes when using it on the road confirmed it was overcooling as it wasnt getting hot enough to evaporate the moisture off but this never happened when using it as designed ie off road in the woods
