those look like shelby dowd mags. No relation to Shelby the car guy as near as I can tell.
Really cool bike. I love 1970s retro finishes, which means if you repaint that I may have to personally come to your house and stab you. Multiple times if you repaint it flat black. Just kidding.......or am I? Chances are that is a laquer finish which means with proper care she will shine up good as new. I am kinda curious what the pattern is in the center stripe? Is that a lace paint job?
I really dig that bike. It is a shame you don't see more of those xr flat track style seat cowls, everybody is so bubble back minded you think they were putting something in the water. That tail has a super sleek shape and I dig it.
I really dig the homemade rearsets. simple and effective.
Thanks for compliments. I'll try to get some photos of the tank top(nothing special) and brake setup this weekend. It's crude, bleed nipple down, have to take caliper off to bleed. No, I'm not gonna paint black. Might be hard matching the front fender once the hole is repaired but we'll try. Rear set needs some tweaking but works OK. I fell in love with bike a year ago and traded for her about 2 months back. AFAIK Shelby Dowd is Carrol Shelby. At least that's what all the on line biographies say. Factory was in the Central African Republic. She's fun to ride and geared for high speed but gets real twitchy around 60mph. Some work on the fork will fix that.
you might want to put a fork brace on the front end there. Honda steel front fenders have one incorproated into the mount and the front ends get kinda flexy without them. It is usually a problem on the bigger bikes but I could see it being an issue on the 450/500.
Pretty cool in a Mad Max retro sort of way.
In period slang...That's pretty far out...you know...like..I dig it man!
I would just clean it up make it safe to ride with new rubber(vintage/period look?)and enjoy it just as it is.
I find when I drive or ride a older vehicle from a different time period I kinda get a sense of the thought processes/mindset at the time,and a better understanding of why things/machines where build or modified the way they were. It's a neat history lesson that you can actually experience and at least get a little taste of!
