Hello old chap from just up the road.

Handlebars - they are adjustable! You can rotate them in their clamps in both directions, which may significantly improve your riding comfort. My Glide was particularly bad when I first got it, but after a few tweaks everything suddenly dropped into place, so to speak.

Shocks - I suggest you talk to Hagons and get a set of their Nitros for your rear end.

Forks 1 - a problem area! On my Sporty I have single-rate springs from Race Tech plus Emulators. I can't recommend the latter as they don't seem to do any good, so I bought Intiminators for my Glide, which I imported from the USA. There is a UK importer, but they don't seem to hold any stock and charge an arm and a leg! PM me if you have never imported stuff before.

Forks 2 - A fundamental problem of Harleys in general and Sportys in particular is that the forks sag too much when anyone heavier than a sparrow sits on them. The consequence is that we are all riding around on only a small portion of the total available travel. The reason for using single-rate springs, matched to your weight, is to maximise available travel and dispense with the short-comings of progressive-rate ones, which are a compromise.

Brakes - I have recently given up on Lyndall as they are just not reliable as a company. Try EBC pads - British and widely available - such as from 'Brakes4u Ltd'. Add a braided brake hose for a little extra.

Hope that helps!
