Hello All
Im looking at buying a 1992 honda 250x. It runs good but smokes so I know piston rings are a deffinate. The engine has a 300ex head on it from what I gather from the seller, and the plastic has been replaced with used 300ex plastic. My question is how much of an overbore can I go before the engine would have to be resleaved? Is there anything else I should watchout for before buying this atv? Does anyone know if its ok to lap the valves, ive been told that hondas have a coating on the valves and shouldnt be lapped. It needs a little work but would be good to beat around on.
