i was on a 20 mile trail and my foreman just started to smoke and burn oil under a load or reving it out of gear, idles fine still. i just rebuilt it with honda parts and a web cam 100miles ago i think it maybe over-heated but the oil temp light never came on . its bored over just .010 the smallest you can bore it.
i tore the engine down and the head gasket was great ,and exhaust valve was black and carbon filled, the intake valve was good,the seal on the valves was good still , the valves had some black streaking on the shalf form the guides and didnt look good , the piston looked new and the rings were sharp and shiney, the cylinder was still in spec with the piston O/D. this is worring me i dont want to spend more money on a top end if i have a major problem somewhere else in the motor.
