Ok, well here's what I did tonight. I put double reeds on the reed block. That makes it really stiff. Then I pushed in on the reed stoppers, to bring the amount the reeds can move way down. Or in other words, reed blocks/stoppers. It will have basically no top end, but the bottom will be really good for a 85cc. I compare it to my KE100 I had. I'm sure there will be some here who will argue with me on how that works. But if you do what I say, you will see. When you buy "torque reeds" they are just really stiff reeds. I happened to have a second set laying around. But you may have to order some or something if you don't have a second set. remember, you can use old worn out one's if you have them, because they are sitting on top, and don't have to seal. Just pressure on bottom one's. My guess is you will need to rejet after doing this mod. Whats good, is when you are done and need the power, you just take the second set of reeds off, and pull the reed stoppers back to stock. You may wanna measure before you bend them from original and write it down. But either way, no need to sell your bike and get a slower bike etc.
Above these cheap things, you can get your bike ported, and have the head milled for more compression, which will give you more lowend as well.
