I know the engine casings are different, but much of the internals are the same on a cosa 200 and PX.
but will any PX expansion fit on a cosa ? or will all that back to front bodywork get in the way...? and the carb won't like it, and so on...
cosa expansion ?
the engine is wider at the mount, and the bracket needs altering to fit (you can chop one side off as a quick way of fitting) i know a PM , and a sito plus will fit , as ive fitted them on a Cosa meself.
Sito + make a Cosa specific system and I am sure PM did as well. Contact the boys in Lancashire. Also Harry Barlow is preparing a performance Cosa engined machine at the moment I believe, worth popping a question there too.
