Hey everyone, I am very new to TWs but I used to own a 71 Yamaha RT1mx, I just picked up a new 2019 and put 200 miles on it since last week. Currently, I am doing alot of in town riding but I am going back to college this fall and I will have access to hundreds of miles of logging trails. My biggest question is since i have been doing many hour plus rides and plan on doing some longer day excursions on the trails this fall, if an oil cooler could help in the long term for engine performance. I've been looking around for oil coolers and I having issues finding the oil cover adapter. I am an engineering student and I have full access to mills, lathes and I might be able to use the foundry depending on how the new covid regulations will be set up at school. If anything, I am thinking on making my own cover and adding a universal radiator kit to it. My major focus is in computer aided engineering so i'm confidant in the design process and production but hopefully ill have enough time for this side project. I'll try to keep you updated if I do make my own oil cooler adapter, but i'm not sure if it is even needed since most of my riding is in Wisconsin and the UP.
