I am a keen Yamaha enthusiast and restorer of the early Yamaha two-strokes twins and
I am always seeking assistance from anyone who has obsolete spare parts
or tuning information that are no longer being used.

All of my 250cc Yamaha's have a 56 mm Bore x 50 mm Stroke and the Crankcases are Vertically Split!

E-Mail me if you have any obsolete spare parts or tuning information
