I have a 2015 xmr 1000 which has heat and melting issues. My usual riding conditions are slow (5-10 mph) with little mud. My xmr has gotten so hot that the underside of the seat melted and my left rear fender plastic was so hot that I couldn’t touch it. So, I decided to take steps to control the heat by doing one improvement at a time to see what helped the most. The first thing I did was remove my entire exhaust and wrap it with D.E.I. Exhaust wrap. This didn’t help at all. So, I then added a fuel controller (power commander v tuned for stock) and that didn’t help at all. My next step was to removed the stock wrapped exhaust and I replaced it with a full muzzy dual exhaust and added a new tune to the fuel controller from VFORCEJOHN. I also noticed that after installing the muzzy the big heat shield along the left side wouldn’t fit nor would the inner one against the engine. So I left those off but left the rear ones beside the gas tank and rear fender. I realized that the plastics would still melt along the left side IF there wasn’t any additional protection added bc of the removal of the big heat shield. So, I ordered from D.E.I their "shield and tunnel II" heat control material. This stuff protects up to 1750 degrees. I knew from taking temperature reading with a heat gun that the highest temperature that the exhaust registered was around 500 degrees. I added this stuff from d.e.i. to the ENTIRE left side of he plastics. I also added it to hoses besides the exhaust. I also added some to the underside of the black plastics that the seat sits on. (wanted to stop heat from getting to seat and from melting the black plastic that the seat and battery sit on). I also added some of it to the underside of my rear fender bc it was STILL getting too hot to touch even after adding the muzzy and pcv. Adding the shield and tunnel II material has prevented any melting of my plastics and has kept any of the plastic from getting to hot to touch. I cut and left the front part of the big heat shield in order to protect the wiring harness and drain tubes from melting….After doing all this my xmr STILL runs gets hot but it can’t melt anything now. I believe after doing the "fan mod" or adding a "Hayden Fan Control" it will be the final piece to keeping the engine cooler….the D.E.I Shield and Tunnel II stuff is fantastic stuff and I highly recommend it over the heat tape. I believe it offers superior protection but it is more expensive. The amount that I used was two rolls….the following are pictures of the areas that I covered.
