Hey guys, so after dropping a valve a few weeks ago resulting in a see through piston, i managed to source an engine from a breakers yard. Had it shipped down from Scotland, visually in a sad state.
After a good clean and some paint, it's fitted & running well. However, there was a very slight, whine when riding, nothing when stationary. I thought it was wind noise at first. The chrome cap on the bevel housing then somehow fell off on the road and was throwing out oil.. I took the whine as a sign of wear, so I swapped out the bevel box with its internals for my old one cos i know it's good...
The whine is STILL there!! Although it's barely noticeable should i be worried? Any thoughts? I plan on lubing the shaft splines as they could do with grease, not sure if that could be it though.
