1986 XT600 Noise after 3/4 to full throttle
Hey guys like I said it’s a noise that only happens under load and it’s almost like piston slap. It sounds deep inside the motor like around the carb area. It only happens after I get on it maybe 1/2 throttle closer to 3/4 throttle.
It kept happening until the head gasket started blowing out the compression and most of oil all over my right leg. The bike still runs but you have to run it light and slow. I’m not running it anymore until I change the head gasket but I want to know what that noise is. As I don’t want to change the hg just for it to happen again and mess up the new hg.
Notice when I took off the rocker cover the two head bolts on the exhaust side were LOOSE and the leak was on the exhaust side (by exhaust side I mean right side where the exhaust is routed.)I tightened those bolts up put the cover back on and the oil leaking got a little better. But eventually came back. Can this be a timing problem? Can being a tooth off timing make that noise and blow a hg? Any help from the xt gurus would be greatly appreciated. Just waiting for some insight before replacing the hg.
Also when I’m idling and I give it a quick blip of throttle it makes this horrid metal noise just as soon as I crack the throttle like piston slap. Only happens when I give it a good blip does not happen when I roll on the throttle more smoothly.
