Yamaha "Big Reed" Cases + Other Billet Goodies
Don't laugh. I found these this weekend. This was the way to go in the early 90's. Weld on "Big Reeds" uses KX500 reed cages. These are brand new never assembled.
make an offer.

I wont laugh In 1973 I had a Penton 125 dirt bike.I had a reed cage cut from a scored RD-350 twin(=175)and had it welded to the cyl.I put aftermarket Boyeson reeds in it,drilled 4 holes on the intake side of the piston skirt and added a 32mm roadrace mikuni.That little 125 would pull around 250 honda elsinore's on the straight-aways,and run away and hide on the course
You might state what size motor the cases are for.

RIVA used to do that mod back in the day. ( looks like their cases). this would be a yamaha 61X 701 case, converted to a kawi 750 type intake, and reeds. they worked very good. this is really were the later 62t case came from.
