Hey all I searched for a while and I couldn't find anything concrete so here goes. 2006 Yz450 with WR lighting system I have converted my bike to a dual-sport via WR parts exchange, and now for the times when I'm riding the bike in town I want to put a cooling fan on it. My question is what operating temperature should I limit my bike to. I'm going to put a temp sensor in a water line then run a little red light in my switch cluster behind the headlight, when the bike reach's the temperature and the light comes on I'll have a toggle switch to turn the fan on. I'm looking at temp sensors from Cole Hersee the options are 184-216F, 253-273F, or 190-210. I was thinking the 190-210 because that is what my truck runs the best at... but I wasn't sure if the temp on these bikes should be hotter to allow better running.... But heat is an engines enemy so.... Any thoughts? Also I saw mention of a spal fan kit? Is this a worthwhile buy or should I just buy a waterproof fan from someplace else?
