1984 YZ490 Exhaust problem

Recommended Posts

Hi all,

I've just recently purchased an FMF fatty pipe for my 1984 YZ490. When i was fitting it up yesterday, I found out that the exhaust port on the motor doesn't align very well to the angle of the exhaust. Anyone have got the same problem or got a solution for this???

The 84 yz is a center port motor correct? Did you get the right pipe? How far is it off , could you post a pic.

You might be able to tweak it a bit by inserting a large (2" OD) wooden dowel (baseball bat handle) into the header and bending it downward.

Use chamber seal to eliminate the exhaust leak, this stuff needs periodic replacing but really quiets a 2/S by sending all exhaust out the muffler. Eliminates 2/S pipe rattle and you won't have all that black spooge on the motor.

1 pack is good for about 5-7 applications if I remember right.
