danman10270 Posted June 25, 2009 Report Share Posted June 25, 2009 Just got me a new project to build.Its a xl185 motor ,bore & stroke are 70x56.4.It has an extrenal oil feed to the cam.Barrel is large finned and shortend slightly to match the stroke.The crank has the same steel bands around the crank as per seeley rs200 ,as does the alternater flywheel.Six speed box.I think the piston is tlr rtl as its kr9 hf1.Will it be any good or will it spin up too quick with the shorter stroke.Frame is Seeley with some sort of alloy seat tank unit.Also disc brake front wheel.Does any one know of any history on the engine or bike.
