That may look nicer than my professionally done stuff Dave. If any of you guys live around the Bay Area Cantwell's in San Bruno does great work.

Beautiful color. I'm trying to decide on a repaint color for my 750S and your purple just jumped out at me.
Is that a true Norton color? I see by your front drum brake that yours is a early year like mine.
My real question is where did you get your side stand? Mine is bent and has no toe lever to get the stand out from under the bike when I set it. I have to get off my bike and look around under it before I can find the stand to kick it down.

Hi Bruce.

Thanks for the compliment.

The bike's a '71 and the colour is "Fireflake Roman Purple" which was a factory colour from '70 to '72 I think. I recreated it using purple metalflake and House of Kolor urethane on a silver base. 8)

The TLS drum was used from '68 to '73 (although only a few '72 and '73 models retained the TLS).

I've upgraded my side stand to the later style ('73) as the '71s were prone to brakage. The '71 and earlier frames need to be gusseted to accomodate the newer stand. The earlier side stands (68, 69) are completely different and hard to source. They're also unstable and tend to sink into soft ground or blacktop :shock: . My '69 R Type has this early style and I just reach down and fish it out with my hand while straddling the bike. Being 6' tall may help somewhat. I'm not changing it on the '69 as the bike is quite original.

Hope this helps.
Tony

If you don't have deep scratches or gouges, you can get a nice durable finish using Mothers and a 4 inch wheel on a drill or other driver. Mothers definitely keeps it shiny for quite a while. It can be done on the bike with only removing a few bits in your way. I have done covers both on and off my bikes on an 8 inch wheel. You have to use a 4 inch or so wheel to get enough tip speed to make it work. A two inch or smaller wheel will not work. Watch the arbor connection so you don't muck up the aluminum.
