Heavy Twins

Good afternoon
I am please to say DDR (Dads Dominator Resurrection) burst into life last night-some of you may recall I posted a while ago with ignition issues.....

Please can someone advise me as to the best engine oil for my 1963 Norton 650ss  to accommodate easy kick starting without compromising wear and tear ? Has anyone had experience with Castrol XXL40? 

I remember watching the film "Girl on a Motorbike" in about 1967 but seem to remember a Norton 650ss being ridden . However I have recently been lead to believe only a Harley Davidson was used..

Anyone make a Carbon Fibre Manx style petrol tank for a wideline ? and are they unaffected by Ethenol ?

Hello all,

Hello all

I'm trying to remove the primary drive case from my 650ss so I can change the gearbox oil seals and replace the left hand serrated footrest tube which has lost all thread. Simple job huh.

After fitting Thorspark electronic ignition and sorting out various electrical issues with the assistance of Al Osborn, I participated in the Jimmie Guthrie Memorial Run a couple of weeks ago.

I used to run my 99 with a 21 tooth engine sprocket, I liked it for touring. I decided to replace the chain and then discovered that I should have had an extra half link, oops, I've been running with a stretched chain.

Hi, y'all
As I've mentioned in previous posts, I'm rebuilding a basket case 1992/3 650SS. I didn't take it apart, I just took away a garage load of boxes, some parts aren't even Norton parts.

I'm investigating why my gearbox kickstart action is so heavy. It's not the pawl and layshaft end float seemed acceptable according to the Old Britts tech pages anyway.
