why run an oil cooler if it doesnt make much difference? I'm thinking of the difference between warm - start of race - and steaming - end of race

i dont have one fitted, but have one to go on, and if it doesnt drain the power when hot then i wont bother, if hovere after 4/5 distance I'm losing 5% or more power I will....and most seem to have then fitted

Who said that, certainly wasn't in anything I typed above

Define warm and Hot
Even with an oil cooler my bike gets hot, just not as hot as it would without one and as such it will not have as much of a power loss with the cooler as without it.
Engines have an optimum running temperature which is what your trying to acheive with a oil cooler, air ducting etc, and ideally thtas the temp you should have your bike up to when running it on a dyno especially if your seting fueling

From what I could see of my oil temp gauge my bike was running a lot cooler in race two than it did in race one, not suprising as the air temp had dropped.
If it had been really cold I probably would have covered part of the oil cooler,
Maybe you have noticed that some racers cover part of their radiators when the air temp drops right down, I wonder why that could be ? could be that to cold an engine isn't ideal, maybe they are trying to get to that optimum operating temperature.

So at the end of race two was my bike warm or hot ? I'm pretty sure it was warm before the RED lights went out at the start of the race
and if it was hot then what was it at the end of race one ? Hotter !!
