crossover question

[FFRDave]

I looked on the crossover table on this websight, and did not find my answer.

In 1999 I bought a new Honda CR 250 and had the stock expansoin chamber, and silencer swapped for another set up. They gave me the stock expansion chamber and silencer and i have never used them. They have been hanging in my garage ever since.

Wouold this 1999 Honda CR 250 pipe & silencer work on my Gas gas ?

I had a 2000 CR250 and they are totally different. The cylinder on the GG uses an external flange that the pipe slides over, while the CR pipe slides into the head.

If that is the same on the 99 I'd say they will not work.
