I am working on a friends 1972 JP, which he dropped off yesterday. It has not been run for 10 - 13 years. The first thing I did was remove the Amal carb. No problem, but I found that it had a reed valve assemble on the cylinder.
I have never seen this before, there is no identification as to the manufacturer of the unit.
Has anyone seen this before? The bike serial number is 702*****.

It's probably a GEM reed assembly. I believe Boyesen still makes reeds for them.

Mike,
Thanks. I was also advised by someone else that it may be a GEM unit, but this has no ID markings on it. A departure from any other GEM unit I have seen.
