Exhaust leak
Kenny H:
My 01 kx5 is leaking at the jug. Looks the guy I bought it from had some kind of heat resistant silicone rubber type he coated around it. Does anyone know of this sealer he might have used.
Foxx4Beaver:
it's not unusual for that area to leak, the rubber o-rings very well maybe shot....Cometic makes some really thick heavy duty pipe O-rings.
I always use silicone when putting the pipe back on, even with new O-rings.
Most guys use the Red high temp Permatex...
I use Loctite 5920 Copper silicone....it's much tougher, and much tougher to remove, but I like it better than the red Permatex....

Not much bugs me as much as orange silicone!!
I just bought a KZ 650 and it has orange on all the covers so now they are all coming apart to be cleaned off.
if you have to use silicone use ultra black # 765-1589 its good up to 500 degrees and nothing on our bikes needs more I use it on all my pipes and being black you cant tell its even there
Foxx4Beaver:
use whatever you want....this is personal preference. :roll:

From the MFG's tech sheets:
Red Permatex max 650°.
Permatex Ultra Copper max 700°.
Loctite 5920 max 700°.
