    reuse intake seals

    I'm curious to know if anyone has used high temperature silicon sealant to reseal viable intake seals. I find it odd that my XB uses a plumbing fitment designed for pressure neutral applications on a low pressure system. That said, its what we have to work with and when my seals came out they were actually in good condition apart from dirt build-up on the mating surface where the seal failed. My Ducati used silicone sealant everywhere and I still have plenty left and was tempted to use it. The reason being that so many folks have had new seals fail to seal. Even my Husabergs use silicone instead of exhaust gaskets and for the casings. So, my question is: has anyone tried using silicone or does anyone know why this might be a bad idea?

    Thanks.

    For the price or new seals and the PAIN IN THE ASS it is to replace them on an XB, I would not recommend this. I’m not saying it won’t work, but when you figure in the time involved, it is a false economy.

    This motor has been around a long time and people have tried to reinvent the wheel on these intake seals since it was introduced. The closest “fix” has been the James blue seals.

    I'm with this guy ^^^

    Stock or James, and follow the manual exactly without adding any old-wives tales.

    You'll want one of these:
    Seems silly, but the amount of time you save will be dramatic

    Yes, I had to modify a few tools to get the job done. Nothing a little creativity and an angle grinder couldn't take care of. Shame I can't angle grind myself a little more patience. I did find some Buell folks, by chance, in their shop (still in lock down) and they've posted out parts (throttle idle cable was shagged).

    When the Bolt seals go, and they clearly will, They're going back in with silicone and then I'll know. Its been the go-to for all my other bikes including my BSA '66 works scrambler. I'll update this thread with the result.

    I've used some fairly expensive white Krytox grease with very good results. $3-400 for a little ass tube of it, but it works.
