A technical forum for Model 7 to Mercury
My Dominator 99 requires new small end bushes - too much wear and it rattles like an old tin can.
I would like to not have to remove the engine and then split it.
Can the bushes be pushed into the rods and then reamed with the engine in place?
Any ideas?
Just thought I’d give a ‘shout out’ for a helpful manufacturer/supplier.
Could anyone tell me if a 1960 dominator 88 should have a high or low pressure pipe to feed the rocker shaft
Thanks

I have been trying to get my 99 to run better, First it was rich, dirty plugs.But went like a rocket while running A new needle jet and nearly seized it up!. back to the old jet and a 31/2 slide to replace the 3 ,spit backs on pick up but sooty plugs on the move. back to the new jet and raise the needle,better running but still spits back. Then looking at the new jet its marked T , with no air bleeds,thanks carb experts! drill the air bleeds , ,,worse, T may mean two stroke?, different internal shape?. Back to old jet and a 3 slide. ,wonder what it will do tomorrow?.
I have a spare drive that needs work ,it is marked 19/10 and BG5330/847 , not sure what it came from . Is it likely to be any use on a Chrono featherbed 99 or Atlas with magnetic speedo??.
Hi. Before I bought my 1960 Dommie 99 I bought John Bacon’s book ‘Norton Twins‘. I needed new wheels building so I looked in the data section at the back of the book, where it states that wheel rims are WM2 size. So I had my wheels rebuilt with WM2 rims. Some time later I bought John Bacon’s book ‘Restoring Norton Twins’. On flicking through it tonight I notice that he says wheel rims are WM1 size.
My 62 99 has the rear brake drum lever below the spindle, have seen a few with it above, which way is ‘correct’ please
Thanks
Hello, I am just beginning a full restoration on a 1953 Dommi 88. During the cleaning process I discovered some rather severe damage to the front frame upright tubes. An associate of mine commented that these may not be accident damage and could possibly be original due to manufacturing procedures back then. This may be plausible as I know that quality control in England back then was not all that great. I’ve restored three Austin Healey’s and they are trouble. So, looking for some insight into this and whether it should be repaired or left alone.
Hi I've just joined the club due to buying a 1960 dominator 88 .The previous owner has attached a breather pipe to the left hand rocker cover and teed it into the crankcase breather .My question is Why has he done this is it a normal upgrade or done for another reason
Thanks for any help

Hi. When I stripped the front forks of my 1960 Dommie 99 barn find, I found that each fork leg had two springs inside. There was the long spring that goes over the damper rod but there was also a short spring (see photos below) that sat inside the oil seal holder/ slider extension. When I look at my genuine Norton parts book it shows only the long spring that goes on the damper rod.
So are those short springs wrong? It looks like they’re wrong but I just don’t know - maybe Norton forgot to add them to the drawing in the parts book?
