OSSA Pioneer 250
The Pioneer 250 kit includes a 28mm D Slide OKO carburetor and a manifold adapter.  As far as we know, these engines had the carburetor attach via a flange.  If, as in other later OSSA models, your engine has a spigot from the cylinder, let us know and we will provide a sleeve instead of the flange adapter.  We provide a sleeve for the airbox, which is a close fit and may require removing the lip from the airbox.  This kit will have your engine run smoother and with more power and better throttle response.
