1953 Dommi 88 DeLuxe Paint pattern & colour.

Forums

Does anyone know where I can access templates for the correct paint pattern for the panels on the sides and top of a 1953 Dommi 88?  I have seen quite a variance on the few restored bikes that I have been able to access photos of.  Some have a "Norton" decal on the right side, on top, adjacent to the petrol filler cap.  Is this correct? I can't find any period, top down photos.

Camshaft Bush Oil Holes

Forums

Doris's engine (1960 Dominator 99) has been dismantled for inspection. Both camshaft bushes have been installed with the oil holes out of line. The camshaft bearing area surfaces are scrolled and Roy Bacon appears to suggest that the combination is acceptable. When dismantling there was plenty of oil in the trough and at either end of the camshaft; indeed the breather disc was tricky to remove being stuck in the oil film.

What do the expert owners think please? Is this folly or was there method in the previous builder's apparent madness?

Hydraulic Bike Lift for Dominator - will this lift work ?

Forums

I have a 1959 Model 50 & a 1959 Dominator, both with wide line frames. I need a lift that allows the easy removal of front and rear wheels and enables working at a seated height. Will this lift from Machine Mart do the job ?

Cylinder head studs replacement on Dominator series + exhaust pipes

Forums

1) Further to recent missives concerning my 650SS, I am replacing the three studs in the cylinder head - or at least, I am trying to. I have removed the one at the back of the head, but the other two, one under each exhaust port, are proving difficult. I have tried putting two nuts on each stud and tightening them together to form a lock nut, then tried to spanner the studs out without success. I have tried using Mole grips, both on the head at ambient temperature, and with local heat applied, all without success. The studs have several graunch marks on them now!

650SS Rim Size Query

Forums

Hello. I need new rims etc for my 64 650SS. I have done some research and feel somewhat confused, not unusual. I intend fitting Avon Road Rider tyres and I understand that to obtain the best combination it may be best to stray from the 19" WM2 front and rear due to modern tyre choice. Please can anyone advise the best sizes to order ie 19"" front and rear, WM2/3/4? Many thanks Paul.

Plunger Model 7 Exhaust Pipe

Forums

Does anyone know where I can buy a left hand exhaust pipe for my plunger Model 7 that actually fits ? Armours can theoretically supply but they dont fit ! (the tail pipe finishes pointing downwards, not horizontal). Have spoken with Raysons and they probably can make me one but could take a couple of months and then I would still have to get it chromed with even more delay. The usual suppliers of Norton goodies dont list them.

Rodark Panniers

Forums

Has anybody out there fitted an original pair of Rodark panniers to their Norton ? I am considering fitting an original pair to my 1956 Dominator 99 and need to give some consideration as to the fixing frame and brackets that I will have to make.  George
