Hi all,
Oil changes to sae 40 and ep90 in the box, head and rocker bolts nipped down and no leaks!
Also received new HT lead caps and carb cleaned, and front brakes working much better after the mech chamferred down the front shoe edges.
Went for a happy 30 mile ride and realised how awful the front end is....like rock hard. It doesn't absorb the road surface whatsoever.
I know when the bike was rebuilt, because it had a heavy Ariel fairing on it, the restorer changed the springs to longer and heavier springs - even side car springs weren't strong enough. So I suspect now I'm not running the front fairing, here lies the issue.
So from experience, would I be better changing the springs back to stock (I'm 105 kgs)? Is it relatively straightforward? Or taking it somewhere for a(nother) rebuild?
Or...can preload be changed? Assume it uses some collars or spacers inside.
thanks
Paul

Is there a "magic number"…
Is there a "magic number" for how far springs should be deflected when you sit on a bike? What fraction of the total range of movement?

The old rule of thumb, and…
The old rule of thumb, and still a useful starting point, is 1/3 compressed with rider etc. seated normally (prop yourself against the garage wall). Bounce the forks to get them to settle. So you have 2/3 travel available for compression and 1/3 for extension.

change the fork springs for some new ones from RGM , I got the progressive ones , seem to give a bit more preload and the bike rides a bit higher. Fork legs have to be removed.. probably will need a puller to replace .
