how do you check if the crank bearings are worn? Can you check it when you rebuild the top end? also, if the crank bearings are worn, will that cause bigger problems if you continue to run the bike, say, till the next top end rebuild?
how do you check the big end bearings with the top end removed?
When the engine on my bike is running, there is a tapping noise that comes from the crank area. It could be from the clutch or the transmission. I am not sure what it is. It does it when the bike is in neutral and in gear. The tapping increases with engine speed. It is a very light sounding tap but it is still there. Sometimes it is louder than others. The best way i could describe it would be to take and run the plastic handle of your toothbrush across the rollers on your chain fairly quickly. The noise is not coming from the cylinder. I don't know if this is normal transmission noise or if there is a problem. There is no slipping in the clutch. I had the clutch apart about a year ago and everything in there looked like it was just out of the shop. The gears do not grind when shifting and the bike shifts very smoothly. there is no performance issues, i just want to be proactive on a possible future problem. I don't know if some bearing is wearing out or something. Any ideas?it could just be normal KX running noises i'd say,judging by what you have said everything should be OK,the only thing i can think of is to check your main bearings,take the mag cover of and try and pull the flywheel back and forwards and up and downthanks, Stang
