Question about 2005 Yamaha DT 125 RE
Pull the left case cover and take a look. Do you see any rubbing marks on the outside of the flywheel? Any marks on the inside of the cover? Any leaves or other trash at the flywheel? Start the bike with the cover removed. Is the rubbing sound still there? Is it actually coming from the flywheel or somewhere else? Turn the bike off. Lift the flywheel up and down then left and right. The flywheel should be rock solid. If movement is felt then you have a bad crankshaft bearing. Replace both crank bearings and crank seals. It would be a good idea to replace the sprocket shaft outside bearing if any movement is felt when trying to move that shaft. Replace the seal anyway.
Check the problem before riding again. Bad bearings may be letting the inside of the flywheel rub on other internal components. That is not a good thing.
