Yeah, I've done quite a bit of work to this bike.........I've got coming as well the RockSolid reed valve. I'll be using a speed carb with it. After the motor was milled down, SBP expansion, and Jag CDI, I'm trying to figure out what would be a good jet size to go with at 2000ft for reed valve. I pray that this reed valve helps the torque, I'm chancing it, because I've been using a 7" extention intake, from jug to carb. Much,Much better torque, but I do believe that reed valve will even do better?!~ I'm hoping that with the higher compression that the reed valve is going to do its thing. I've port matched all, but not opened up engine?!! We'll see....................Did reed help yours? What kind?
