I've NEVER owned a set of Boysen Reeds that would seal.

I run NOTHING but the Tony Doukas Racing Reeds in my 11,000 rpm race as well as recreational motors, my customers love em..

From MY experience ,
Jay

Thanks.
Considering fitting some to a yamaha 90, but only if the gain is worth the pain.
Any idea what the gain would be?

I've always thought of them as an easy way to tune up your engine in a safe way without big engine changes. The advertisements look very promising. But I don't have any real life experience with reed testing.

-> If Jay advizes not to use them, then don't !

There was a reed test done on Scream and Fly a while back and the Boysens made OK power BUT quickly faded after several pulls and the others didn't..

I like and run nothing but the TDR reeds because of their 100% success on my rebuilds..Its just one thing I can remove from the failure equation on customers motors..


Cheers ya'll .
Jay
