Just heard through the grapevine that Cornerspeed are in the process of developing an 855 kit foir 748's.
As far as I can gather he is having special pistons made in the states to keep the weight the same as the smaller 748 pistons to avoid having to re-balance crank - and of course strip the engine down to far!
He is getting the cylinder bored and nickersil plated locally though. Can't wait to see/try the first one!
