I have been looking at Reed valve spacers and am interested if they really produce a valid result or are they just a gimmic? I had one on a 00' Yz125 I had, but I put it on at the same time as I changed gearing and would not have been able to tell.
what it does is increases the volumetric efficiency in your crankcase and might alter your primary compression i have heard of it being done after you stuff the crank
How much digging on the subject have you done? There's a ton of info available. Also perhaps you are expecting too much from changes. Bikes are pretty much as good as they will get for the most part and everything is fine tuning.
Oh I remember. I've been a member since 00' and though this place doesn't get as much traffic as some of the other sites it is VERY helpful. I LIKE the fact that it doesn't get as much traffic. It keeps the useless rambling down and the helpful info up. ;)
