Suzuki RM250 ring catches in inlet window when fitting cylinder; also applies to some other engines. Ring end opens into port when installing cylinder; use a suitable tool to guide ring into cylinder. Do not force cylinder as this can damage plating/ring/piston.

If used in Karts they generally require more piston clearance also earlier cylinders with auxillary exhaust ports may sieze on the bridge between these ports. Remedies that have been tried are 1:- polish a little extra clearance into the bore at this point. 2:- file a little more cam profile onto the piston at this point |
