Heavy Twins

Hi can someone tell me what this is called,I've just noticed a crack in it so I need to fix or replace it? It goes from the top of the engine to the rear petrol tank fixings. Many thanks

Please someone give some comparison to two bikes with regards to kick starting ease.

Apologies for the clickbait title.

I've been working on an early 650ss engine with a 99 barrel and have had a few false dawns. I've been working on carbs, clutch, oil lines and rotor/stator up to now.

Help! I'm slowly recommissioning a 650ss which seems to have been cobbled together from the parts bin somewhat over the past 60 odd years. I'm also battling my lack of experience with Norton's this being my first restoration of a Dommie. 

Hi my mate has just purchased a 600 dominator and joined the club but is not yet conversant with the procedure to post a problem so ive done it for him.

I believe my recently acquired Domminator 99 would have originally had a connection to the air box behind the battery but it just has an open carb without even a bellmouth.

I have a  fully restored carb by Martyn Bratby ,beutifully machined . The issue is that its a 389  with a 1 1/8"  bore .  The standard carb is 1 1/16" .  Its not a simple change as other components will need a little work.

For those who like to experiment ,I have run out of the 10/40 fully synth that i got for free a few years ago and have returned to the good old SAE 40  of yore for the 99.  I have noticed that the motor is much harder to kick over but is not so cl

I've recently taken on a 1958 Dominator 600.
