Firmer fork springs for non SP GK76's.

[wullie3xv9]

Hi folks. Been along time since I asked a question, so here goes.

Have any other GK76 owners fitted firmer front springs to their non SP, spring preload adjustable only forks?
If so, was it worth it? What make, type of spring, (progressive or linear), weight of oil & air gap did you end up at or did you stick to the spring makers recommendations? (I see Wilbers, Hagon & at least one other make stiffer front springs).

The reason I ask is that when I serviced the forks on mine the stock (progressive) springs were at the top end of their free length limit. But on rebuilding them with (Silkolene) 5 wt fork fluid & the air gap set to the stock 97 mm's I've concluded they're too soft for my 84 Kg carcase on the rough arsed country roads that abound in my neck o' the woods!

With the spring pre-load adjusters wound virtually fully in, ( one line showing above ) the static sag is at least 40 mm's, with it sinking around another 10 mm's when I sit on the bike ! As they are now, in general they soak up big bumps quite well at speed & I've never experienced any tank-slappers (so far) ... but .. when I hit large bumps if hard on the brakes there's a solid clunk as the forks bottom! Not good for my nerves! ( Or the forks! ?)

I've spent a chunk of today trawling through all 42 pages of threads in this section on this very subject to no avail.
Any usefull advice/recommendations gratefully received.

Wullie.

HI Wullie. I haven't got a 76a, but I recommend you phone KAIS or someone similar, and give them the specs of your springs. I have bought Ohlins linear springs in the past, and put them in bikes. Ohlins make tons of springs in different lengths etc.
If you are unsure of your spring rate, you can send a spring into them and they will measure it.
Only thing is I wouldn't go too hard, as you will have incorrect damping characteristics, and then you will need a revalve..
