I have my '88 toren do to put in a new crank and have decided to do a little hopping up. What kind of reed valve is the best? Are Boysens worth their price or should I go with a FMF Ram valve? I ride on MX tracks and have a LRD pipe Wiseco piston and re-jetted stock carb. I also plan on having the cylinder ported for MX. What does a reed spacer do? Thanks!

Personally after trying the Rad, Ram, and Pyramid valve I like the Delta V-Force Reed cage the best. It is just my opinion thought.

 

For the reed cage. Go with the V-Force Delta 2, As with the other reply it is better than the others. I also know that the Ram Valve is probably the worst. I dont know about the pyramid, but the Boyesen was good, just not as good as the Delta 2. Dave

 

Oh yea, and as far as reed spacers. They make you bottom end more responsive and smooth any hard hits in the power. I have one and like it. Dave

 

Thanks forthe info guys. I'm going to order a Delta V-Force and a reed spacer tomorrow. Turns out that I also need a new clutch basket. Any advice on which one to get?

 

Contrary to what other people may say. The reed valves are actually pretty similar. You can modify them to do what you want just like anything else. The reason that people say the FMF doesn't work as well is because they don't come with Dual Stage reeds like my RAD valve did. I feel that the key is not really in the reed cage, but in the actual reeds. The dual stage reeds are a little better because you get more power everywhere. Reed cages can ported to meet specific power characteristics. I am sure that you will be happy, with the Delta cage. As far as the reed spacer, the theory is that the fuel air mixture has a greater velocity when it enters the cylinder that is where the power gains come from. For the clutch basket, there are 3 that I know of. Hinson, Magnum-Vortex, and Speed. All of them are billet and all are pretty similar in design. I have a Magnum-Vortex personally and it works great and it was about $40 cheaper than the Hinson.
