So the setup I am going to end up with is the Yuminashi 160cc Big Bore kit, Yoishimura RS-9 full exhaust, and Chimera air intake. Will an Oil cooler be necessary or even help out at all? I do a lot of mountain canyon and high altitude riding. There was another thread on here about Oil coolers but no one ever really answered the question about a non-stock Grom. I know that with a stock set-up it is not really necessary.
