I decided to buy a 2004 RX-1 Mountain after riding one for two days in West Yellowstone this season. The RX-1 I was on overheated anytime there was a hard packed trail and I was on the throttle for any length of time. Even with the overheating the sled was great in the loose stuff and I still decided to buy one. Does anyone out ther know if the 2004 models address this issue from the factory or do I have to take matters into my own hands. I asked my dealer and he never heard of it. Everyone who rode RX-1 mountains that I've talked to have had similar problems. If the solution does not come from Yamaha then I want to have a plan ready to fix it myself. Any help would be appreciated. :?:
