FSR450 fuel tank ??

[BigG]

I emptied the fuel tank to put fresh fuel in (it'd been sitting a long time). I found a ball bearing, 6-8mm diameter, in the tank. Can't see where it may belong. Any ideas?
Thanks

It could be from fueltank cap, there is one bearing ball inside of it.

That would maybe explain the fuel I saw "bubbling" in breather hose. Will check it out tomorrow.
Cheers

If a ball bearing fell out of your fuel pump i suspect you would notice it, by the sound of the pump (if it would run at all).

However I would remove the tank and the fuel pump for inspection, just to be safe.

[edit]
It is not a complete bearing? With inner and outer races? Only a single ball?

Yep just one ball bearing.
