I've owned my 500 Classic from new in 2007. It's only done 4000 miles or so. I had a look at the oil pumps a while ago and all seems fine - no wear to spindle was evident.

Recently, until the engine is warm, the right footrest vibrates - almost feeling like pins and needles in my foot. After a couple of miles this settles down, and there is no untoward vibration.

When the head banjo union is loosened, plenty of oil flow evident.

Does this right sided vibration with a cold engine sound oil pump related? Has any one else experienced this?

How might a failing oil pump manifest itself - other than via a knackered crank?

Thanks folks !

That does sound strange. First thing I would check is the engine mounting bolts and head steady.

Thanks Pete. Just checked - all tight. I also had the gearbox outer cover off because I know that the inner cover screws work loose. Sure enough one was flopping about (the difficult to get to one behind the neutral finder, obviously). Now tightened. I'll see if that improves things. Thanks again for the suggestion.
