My CR250 has been diagnosed with a leaky silencer. Now i know they are supposed to or are known for leaking a little bit out the back end of the silencer but mine is leaking out the connecting joint between the silencer and the exhaust. I just dropped over $300 in the bike to stop all the leaking issues i had prior. The bike was jetted professionally, fork seals rebuilt, and new exhuast gaskets to stop the exhaust from leaking. Now im still left with the black swing arm after riding for a few hours from oil leaking out the seal on the silencer. DO i need a new seal that connects the silencer to the exhaust? All that protects oil from coming out the joint is the silencer is fitted into the exhaust and the a rubber seal out side of it. Do i need new silencer packing? Any help appreciated.

If it's leaking that much oil out after a ride, I'd suspect that the jetting that you had done, isn't quite right.

Yes, that is the before photo, now it only leaks about 1/3 that much oil now that it is jetted . But it is still getting on my brake rotor which is not good.

I think that along with new silencer packing and this - http://www.rockymountainatv.com/pro...8&vehicleType=&pageLinkUri=&prodFamilyId=8819 my exhaust will not leak at all.

Cman, here try this link. http://houseofmotorcycles.bikebandit.com/parts/Honda/CR250R/2002/1135247
If u buy part #11 on the list, your problem will be solved. You can also put some high temp silicon between the silencer and expansion chamber just to be sure. ;)

repacking the silencer is only a band-aid fix. If it is "leaking" any oil at all it is not jetted properly. it should barely even smoke let alone spurt oil out.

True to an extent, but...the pipe and the silencer packing is probably saturated with spooge from before the jetting work was done. That stuff just doesn't go away! It needs new packing.

The pipe to silencer coupler was supposed to be there from the factory. They designed it that way for a reason. Get one, either OEM or aftermarket.
