Heavy Twins

Has anyone tried a JSMotorsport JS0 cam and lightweight lifters in a 500?

I am replacing some of the bolts attaching the gearbox outer cover to the gearbox shell. According to items I have read, the required bolt size is ¼"BSF, so I ordered some, which arrived today.

My question to members.
Is it necessary to fit the leather seal between the bottom yoke and fork cover.
Thanks for any feedback.Denis Curry.

Hi all, I have a 1955 Norton dominator 99.

Hi all, I have 650SS, it's engine number is 18SS/M 116188/P, I know the P stands for Plumstead but can anyone enlighten me as to meaning of the M?   Stewart Denton-Giles

Hello, I just have a bare stand for N15CS. Has anyone got, or know where I can find, a schematic how all the spacers etc fit. Thanks Richard 
 

Hi - i am a new member and about to start rebuild of a 1960 dommie 99 with no v5 for it. Its likely to take sometime as i have several other projects to finish first and many items still to buy for the dommie, so its too early to get a dating cert

I'm just putting the finishing touches to my '63 Norton 650SS restoration. I've applied the "Oil bath" water slide transfer to the primary chain case.

Hi All,
