Silicone Question.....

Is it OK/Safe to use Copper RTV High Temp Silicone to seal a 2-Stroke pipe at the Cylinder??

Thanks........:ride:

i've used it before at the pipe union. but not at the head

Same for me, never used it from flange to cylinder, but pipe to flange where it slip fits can help to reduce splooge that a 2 stroke makes.

I have been doing it for years, works great, no spooge, no exhaust leaks and the bike runs better. Clean the pipe and spigot completely with brake cleaner and put a thin film on the pipe and slide it in Use new orings too. I buy the Viton orings from McMasterCarr in packs of 10 for $14, and they make a slighter thicker than stock oring that works great on my KTM 300.

Is what FMF recommends to use on their pipes.
