Thanks for the reply Simon will do.

Hi all,
I have just finished restoring my 1953 NH 350. It was found in a hedge behind a farmers barn so therefore the documents are missing.
I only have the engine, gearbox and frame numbers. Is there any way that the club can re-register it for me.
Look forward to your replies on this
Many thanks ...

Well Simon although everything checked out as you said still no oil returning to the tank or rocker feed.
It looks as if I have tp bite the bullet and take the engine out of the bike and investigate further. Many thanks to everyone for your help.

Thanks for the reply Simon.

Hi Guy's,
Further update. I have blown through every oil connection including the sludge trap, flow and returns. Before doing that I checked the ports into the crankshaft for crud with a drill as suggested but nothing excessive there.

It looks as if there is a blockage in the crankshaft am I correct thing this?
Simon what size drill did you use to unblock the ...

HI Simon, That,s a good tip I,ll give that a try today.
Did you do the twist drill job with the motor in the bike or stripped down on the bench?
I shall report back if I get any results

Pete that,s a good point.
I did not delve any deeper into the sludge trap to see if there was any crud coming out of the crankshaft.
This is what I did today. Removed pump and sump cover. Lots of oil came out of the sump. Then I blew compressed air through every port under the pump area ...

Wow Guy,s Lots of good info from you to get my head around.
Yes Pete I agree with you a picture is a great help. Unfortunatly I am not that good with computors and I do not know how to load and annotate them like you can. Any lessons on that?
One last wild thought. If I blow air into the end of the ...
