Very nice collection of Ascots & parts!
It's always good to maintain a good clean stock Ascot. Or as stock as possible. Looks like you have enough back-up parts so you can maintain a stock bike for a while.
They are very simple to modify for better performance, if you can locate the correct donor parts. The first generation Honda CBR600 Hurricane is what you want if you can find it. I believe the years of Hurricane are 1987-1990, but I'm not 100% sure on that. The Hurricane forks are the correct diameter & spacing to slip into the original FT Ascot triple clamps. Plus the rear wheel & brake assembly slides right into the FT Ascot's swing-arm like it belongs there. All you need to do is fabricate a simple brake caliper stay. This gives you a lowered bike with quicker handling, better forks, dual disk brakes up front & 17" wheels on each end. Makes for a very fun Ascot! Plus it could be returned to stock if ever desired.
Alternatives to finding a CBR600 Hurricane donor makes the swap more difficult, but not much more, depending upon what you find for a front end.
Good luck & please tell us more about your "modified" bike plans.
