Thanks guitarfish, that was perfect.

Nice looking bike with the extra chrome.

Thank you for taking the time to make the video.

 

That's more like the Scotland I know, there's a lovely view out there somewhere....

 

Dimensions of wide vintage solo. Same length as vintage as shown by guitarfish, but 14.5" wide outside to outside of seat.

 

You got it buddy, happy seat hunting.

 

Thank you Grey_Beard.

Another nice looking bike in the sun.

The yellow and chrome look good together.

I have the 430 shocks on my bike for the no tool adjustment.

What springs do they have, if not rude your weight and how many turns of preload did you need please?

 

Andy, I have the preload set for 1" of sag. For my 185 pounds that would be right at the 3rd ring from the bottom. The easiest way I found to get the correct sag setting was to use the tip of the exhaust as a pointer against a tape measure. Set the tape to be at a whole inch increment while not on the bike. Then sit on the bike and see the difference. Adjust the shock collar and repeat till you get the sag you want. I have the standard springs and the shock length is 12.5"
With the mustang wide vintage solo seat and the progressive 430 shocks I can ride all day long with zero discomfort.

 

Many thanks.

Just as soon as it gets a bit warmer...
