Heavy Twins

I had posted about my silencer which was hanging loose because the bolts had vibrated themselves off the bike and it was hanging loose. 

I am restoring a Norton Dominator 1955 88 Deluxe

Can anyone help me? I have an oil pressure problem on my 1949 Norton Dominator model 7. When I start the engine cold the pressure goes up to 100 Lbs. When the engine is hot the pressure drops to 10 Lbs and sometimes even 0 Lbs. I use SAE50 oil.

job for this weekend.
When I undo the throttle I won't end up with pieces disappearing into space never to be found again? Is it a straightforward process?  Any tricks?

thanks

Hi as my bike was rebuilt with an Avonaire fairing, my front forks are very hard - side car weight
springs were added and without the fairing, it tends to crash around on our bumpy potholed roads.

I'm trying to ID this works fuel tank...could it be from one of the Domi Racers.....

..not a performance enhancement...

When out for a run to run in my 1960 Dominator 99 I heard a bit of a tapping sound, I thought a valve tappet needed adjusting.

Need some education with cylinder head for 1967 N15CS

What's going on with the offset counter bore, does it serve any purpose ? Looks like a squish band but what not full circle ?

The Dominator 99 I took over is fitted with bronze/steel clutch plates. (I assume sintered bronze).
