Hello all!

Does anybody know the thread size of the Navigator rear petrol tank securing bolt

No. A2/277?

The thread in the frame bracket is shot and I cannot secure the tank properly. So a helicoil insert is in need.

hi - I have a 1959 Dominator 99 and need to know the correct gearbox for the engine please and the price I would need to pay for the gearbox. Many thanks - Dave

Just fitted an RGM front brake master cylinder conversion. For the life of me I cant get the damn thing to bleed.

i have a 72 registered 750 commando which is proving to be somewhat odd. Registered 72 and distributed to Gus Kuhn in jan 72. This has matching numbers in the 200,000 series.

I do not own a 961 just a Rotary and a 650 SS, on FB today there was some typically negative comments concerning the new Norton's (Atlas etc) from one who admitted to not owning or riding a Norton and another who is a sales person for a well know

The DVLA require my newly re-built 1965 Jubilee to have an inspection by SGS before assigning an age-related registration number (the bike had no paperwork when I bought it and was in bits).

hello, some while ago in a magazine i saw a Dynastart fitted to a single cyl bike dont know if it was a norton.

I have recently acquired a '56 Dominator and cannot reset the trip meter to zero. The adjusting knob will not withdraw to engage the mechanism.

Hello all, looking to rewire my 72 Commando anyone got sources for wiring cable etc.

Can anyone tell me the wire size ie dia.

Cheers all.

I was missing the inspection cover on the right-hand side of the gearbox so decided to make one it's very non-standard but I like it.

I plan to black the engraving and the screws in the photo are temporary.

On the back of my Navigator enginenear the chain sprocket, there is a hole that I think is a crankcase breather, there was a 3/8 brass bolt with a hole up its centre ramed in the hole.

I fitted a new extended nut to my Model 88 under the left exhaust port. As it began to tighten, the thread stripped. The stud has pulled from the head. That means the head has to come off for a helicoil.

This bike has adopted me to be its caretaker for the next few decades (I hope). My plans are to get it into excellent running condition and enjoy it until a new caretaker is needed.

I Have a 1972 commando interstate the engine and frame are mid 204000 range.

Hi all,

Any experience of running a Lithium battery?

I see at the back of OBM an advert by Powerlite for 5 Ah and 9 Ah batteries - anyone fitted one?

Found these in one of the boxes and they are obviously end caps for springs but can anyone tell me exactly where they should go? Many thanks Ron.

Can anybody shed any light on why some OEM Slimline petrol tanks have the filler on the nearside (left) and some on the offside (right)?

Hi just a word of warning I am in process of assy late navi crankcases and am at point of putting timeing cover on and have found the inlet camshaft is were ex should be.

Can anyone confirm what the correct arrangement should be with regards the attachment of the knuckle and ratchet plate on the selector mechanism in a Laydown gearbox.

Bike is 1959 Dominator '99' - history largely a mystery ! I found it impossible to set valve clearances directly due to poor condition of adjusters and lock nuts. The replacements at 13/16" in length, supplied by RGM, are too short.

Hi I'm just starting to tinker with my late father in laws 1929 model 18, now i'v been able to get it up on the work platform its not to bad OK everything made of steel is rusty but it seems to be solid.

Hello All.

Just running theoil lines from the filter, and notice it is really close to the swing arm spindle and will rub onthe plates.

This may not be the correct place to put this , but how many other 961 owners have received an invite to look at the new 650 next Tuesday night down at the factory.

I ride a 1957 !9S (pre featherbed), I am currently running with Maxxis tyres front and rear which leave me with no confidence in damp/wet (just dumped me on my a**e on a damp roundabout, bent the footrest and pride hurt).
