Hi, I am looking for some information on the repair of a an Advance & Retard unit, The unit is stiff and does not fall back to the the retard position. 

removing the bottom nut on the 650SS is a problem.  Unless someone makes a special spanner I am going to have to cut up one of mine. Could drill out the stud from the timing side !. 

Changing these to chrome but cannot decide on round or rectangle type bar end mirrors for by '61 Dom 99 DL.

What is the preferred style?

thanks
Paul

Hello, I have a N15CS without a seat and want to make a 3/4 length seat, bit like P11.
Does anyone know any other seat pans that fit the N15CS frame.
Thanks Richard 
 

Anyone tried one? Do they blow the fuse? Have a 12v conversion. 99 dl. 
I've got a full length crack on mine. 
I can't find single headlights but found a pair of 7" for a mg which look like it'll fit with h4 bulb and pilot. 

The current (Feb2025) issue of Classic Bike has a nice piece by Ric Parkington about the Pll hybrid. As well as a brief history of it's genesis, there is his road test, and some period adverts.

Hi all. Has anybody any feedback on the Bright Spark Bright Cap condenser conversion.
My condenser has failed and I am considering this option after wrestling with the lower
maggie bolt on the model 7. Cheers.

Morning all. 

Good afternoon 

The resurrection is going along well, awaiting return of the frame to start hanging all the shiny bits back on and the next challenge is.......
Where to get a period looking Manx tyre fly screen, any ideas anyone?

I'm going through the gear box on my Dominator, gear box #N24006. The mainshaft 2nd gear is usable but I would like to replace it with a very good one if anyone has a good spare. It is a 18tooth gear with 3 engagement dogs.
