Pro-Form-Racing (PFR) exhaust on 1977 Bultaco Pursang MK10

Bought the pipe from AMS racing... unfortunately it was for mislabeled and was made for a different year.  The bracket is too short and the head angle is off about 15 degrees.

The gap is between bracket and mounting hole is shown here.

Fix for the bracket.

After cutting off the head pipe and aligning to the exhaust port the pipe fits as it should.

Billet Innovations Air Box for 1977 Bultaco Pursang MK10

The build quality is excellent.

The air box is a tight fit.  One of the shocks has to be removed to install it.

It's hard to get at the back fastener to remove the side panel.  I plan to rubber mount the air box after I install the carburetor  and align the inlet/outlet.
