Vintage Dirt Bike Q & A

I need some recommendations on what pipe works the best on the 79 CR125R. My engine is stock with the exception of a 34mm Mikuni and Boyseen reeds. What are the advantages or disadvantages with each pipe. Thanks Mike

Mike,

I've wondered about this myself. I can't find any old test of the Jemco pipes.

The Jemco pipes look neat, but I think the fact that we don't see the abrupt cone shapes anymore should be a clue as to which pipe is the best. Look at all the Factory Works pipes from 1980 on and the modern DG, FMF, Pro Circuit, Bills pipes, etc...

Hey Mike,
In reference to your question, it is my personal opinion that the Pro-Form pipe is far superior to the Jemco pipe. WeÌve tested a lot here on our race bikes and the Pro-Form pulls a lot better and produceÌs more of a wider power band, so you get away from that light switch power band, that the Jemco seems to just give you more of. In fact the Pro-Form pipe is so good we even guarantee it. It is the best pipe on the market today.

Good Luck,
