    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.

    Yikes. I thought the header pipe was stainless steel.

    Glad your bike didn't burn up.

    Baked on mud does not stick like stock. Washes off pretty easy.
    Can't really tell if it has any effect on fuel tank temps. Can't hurt tho.
