No worries Pete. Happy to help a brother and a fellow local to me self employed businessman. Everybody wins, gotta love it.
As for the seat artwork. What I have done in the past on different projects is find graphics/artwork on the internet, download and resize on my computer and print it out on sign makers mask or artists mask to make my own stencils. Then tape it to a light table and carefully cut it out with a sharp exacto knife. Carefully clean surface and peel off backing and attach stencil. Mask off rest of seat/whatever to catch over-spray. Make sure all corners are pressed down well or you'll get some paint bleed. Which you can clean up but the edges won't be as crisp. Spray several light 'mist' coats until you're happy with coverage. Don't let paint fully cure to hard. It might be a little brittle and you could lift off sharp corners when you remove the mask.
This would work if you're going to remove all existing lettering.
As you're probably going to paint over the existing logo, making a stencil and getting the size right on a computer would take way more trial and error attempts than I would have the patience for....lol. Major PITA. Also you may find that if you measure the width of different parts of each letter they differ. Trying to get a match for that printed off your computer, likely not.
So, what I would do is still use sign makers or artist mask, cut it into strips and simply use pieces to mask around your letters.
A local sign maker would likely sell you some mask, they have big rolls. I have also found it and artists mask at Curry's Artist Materials. Don't know if you have one in Windsor but other art supply stores would carry mask.
Special vinyl suitable paints are available at Canadian Tire.
Whichever way you go, make up some extra stencils and practice on something to get a feel for the paint and cure/removal time.
A fun Saturday afternoon project.
Enjoy your new seats!

never fixed this issue on an expensive top-end bike that had a production run from 2003-2014 with the ST1300 and was sold all over the world.
