I know the 200sx is a quad and maybe I should have posted this in the quad section but sense it is intended to be swapped into a trike I think its fit for trikesylvania.Ok does anyone have any experience with the 200sx engines? They are very similar to the 185/200 engines but have a few differences there chain drive,have reverse,no low range,and electric start tucked up close to the back of the cylinder. The head on them looks different too but im not sure if its just visual and not mechanicaly different. So back to the point I think this would be a sweet little engine to use for a auto-x conversion! Anyone used this engine in a trike??
