I,m computer stupid,don,t know how to link stuff. But Boyeseen makes the rad valve, the hgs bud pipe I purchased from Langston racing in the USA. The pipe is made in Holland, distributers are in Europe. The hgs pipe made for the 05-07 cr125, I heard is suppossed to have a big mid increase. Langston used to be a Doma importer, they had a few hgs pipes for what ever reason. On the internet I heard a kx pipe increased the low to mid, on the cr125. If your wondering that,s why I tried a kx pipe, I figured that I would get a low to mid increase at least. There,s quite a bit of fab work, cut the stinger-back of pipe and some of the silencer stinger off. Pound the pipe in to get clearance for the kick starter, bending in the stinger area, make a bracket for the rear pipe mount, have to use kx pipe springs, the stock front mount is still used. You just keep tweeking it until the pipe doesn,t touch the frame and stuff. The pipe has a super fat cone, the closest you can get to a factory Honda pipe. I grinded a little off the inside of the kick start lever also. The clamp I mentioned is just a piece of flat steel, drill 2 holes for mounting, a piece of rubber that the bolt goes threw, to deaden vibration. Kinda of fun project, that anyone can do in a afternoon.
