I know my oils, but I wanted to know if anyone experimented with different oil weights? Which would have the best cooling effect? I am sure the lightest weights will make more power, but using "radiator" theory (more flow against hot part, cooler it is), would it also make your bike run the coolest? I have seen that two2cool stuff, but I don't want to use it because I don't know what it is? Heat is from friction, so it must be a friction modifier, right?
