I have an '83 FT that is mostly stock. It is a fairly low mile bike & I plan to keep it as original as possible.
Either I, or the P/O, have performed most to all of the tricks described in the "Ascot Essentials" such as the petcock mod, air-box mod, jetting, 16 tooth countershaft sprocket & a Cobra F1 slip on muffler. These tricks have turned the bike into a great runner. I have also changed the original tires to a pair of Avon Road Riders. The bike is intended to be strictly a street bike & dual-purpose tires would just not do for me.
I ride the bike fairly aggressively & love the twisty mountain back roads.
I have picked up another FT500 that was involved in a low speed dump. That bike is receiving the full treatment more or less & will make for another posting down the road.

UPDATE: I have since installed the ThumperStuff performance header & the Rick's CDI ignition. The bike runs even better than ever.
