    Hi CH members
    last sunday I noticed, with the motorcycle just turned on and in back light, a little smoke coming from the header-silencer junction. I was thinking this weekend of dismantling the silencer and giving a veil of motorsil (an heat resistant silicone that resists up to 300 °C) that I use in the 2T junctions because is the olny thing in my garage I can use to try to seal it.
    It has already appened to you, what you used as a sealant!
    Many thanks

    In the states we have a product called heat resistant RTV. It may be the same stuff as motorsil just a different name. I used it to seal the same area on my Husaberg in the 90's. It got the job done but if my memory serves me right it would eventually loose its sealing ability due to vibration. It certainly wouldn't hurt to try it since you have already some.

    I've searched RTV High temp silicone and they are pratically the same thing. This weekend I try and let you know

    On the instructions that came with my FMF silencer it said to use hi-temp silicone to seal the connection. I used a red hi-temp and it worked for a while.

    You can’t go wrong with any of the Loctite products out there ... I used this when I repacked my 296 FMF silencer so far it’s holding up good D168D34E-DD24-41BE-A4FF-37F87F8D1551.png
