When I bought my 950A the previous owner had wrapped the front header from the guard forward. I was worried it would rust underneath and for some reason figured it was bad news so when a spare cam up on here for sale, I bought it but didn't get around to putting it on. I was out riding Sunday and on a downhill I whacked the right tank guard on the 950 pretty hard. Enough parts moved that it cracked the header. I couldn't feel or see the leak, but I could hear it. When I got home I pulled the right tank off to inspect the header. It didn't feel right and when I pulled the heat wrapping off I found a lot of rotten metal and it basically fell apart on the floor. The wrap had held it together for about 2 hours. The hole had been on the bottom where I couldn't feel and like a plasma cutter, torched a hole in the plastic side of the skid plate and melted the top cover of the relay switch for the starter to the starter fuse. When I pulled the cover, the fuse came with it. As you can see, things got tight and toasty down there. I am lucky though, could have been the gas tank I am lucky also in the fact I was worried about what was under the heat wrap so I bought the used header (here) for $35 about 1 month ago. KTM price $243.00 Thank God I am a hoarder!!! I Couldn't find any thick heat foil for the tank so I ordered some from the local KTM shop. Unless you live where it never rains, don't use heat wrap.
