The 1986 and later ATC200X engine is completely different than your xr200/tlr200 engine family. Nothing is in interchangeable from the 1986 and later 200x engine and any tlr/xr engine. You need to look for a 1983-1985 ATC200X cylinder, which will bolt on with no modifications. Be aware if you are looking on American ebay, most 83-85 atc200x cylinders listed are scams by fraudsters and are just regular small fin cylinders. The supply of big fin ATC200X 1983-1985 cylinders has almost dried up because of the great demand and some people are trying to sell anything. I've done many of these swaps over the years.
