Posted December 10, 201014 yr Gents. Im after diagram of the engine in my WR125r. Theres a couple of parts i want to find out about. 1st is a little black "valve" type with a airpipe from the airbox through this "valve" into my exaust (just down from the manifold) This is just a guess but does it blow Cold air into my exaust to lower emmissions? If so surely this will reduce back pressure obviously reduceing power. Also can anyone reccoment me a full pipe for my bike? Many thanks Paddy
