I own a 95 scrambler 4x4.I just blew-up the piston. Ordered anew Wiseco piston at .0030,had the jug bored out. In reading the directions on piston 2-cycle, if the cylinder has an exhaust bridge,the piston should have lubrication holes on the skirt where it contacts the exhaust bridge. If not you must drill holes.My question is does this motor have an exhaust bridge? Or do I just install piston the way it is.

 

No bridge on your cylinder, Honda 250r's have the exhaust bridge....
