PT mid O'ring

[Bairdy13]

Hi guys, Would anyone happen to have a pic of the sealing face of a set of pt mids where the o ring goes? I dont think mine are in the best shape after loosing 2 new o rings after 2 rides. I just wanted to get an idea of what there ment to look like before I attempt to fix them.

Cheers

Al

Ok can anyone tell me if the sealing face is ment to be flat or groved where the o ring sits in?

Any help would be great.

What year are your Paul Turners? The older ones did'nt have a grooove for the o-ring in the pipe.

It has 92 on the plate though im not sure when they were made. I think I will just weld an over size washer type thing in there to flattern it out.

To prevent the pipes from wearing into the cylinder slip a custom large washer over the exhaust then just seal the pipes with high temp silicone when you slip them on. They don't use the o-rings.

Arrr sweet I didnt think about the silicon! Where abouts do u put the washer? between the exhaust and the jug on the exhaust port?

Cheers :beer:

Yes, You probably won't find a washer large enough that is thin. If you use a thick washer it may misaline the pipes to the silencers.

I use high temp black silicone to seal all my pipes to the cylinders, even if the pipes use a oring. I don't like black goo running down the front of my motor.

So the washer sctually slides into the pipe! just want to make sure before I go out and make them.

Cheers Lepew 4 the help, very much appreciated.

The washer fits over the exhaust port of the cylinder and the sharp edge of the pipe that normally wears into the cylinder will wear into the washer. You could put a washer into the pipe like you thought I meant, but I am not sure the pipe has a consistant shoulder for the washer to lay flat on.
