Yes I look forward to finding out how spring ratings translate into quality of suspension from the front forks. Can I pick your brains again? What tyre pressures do you recommend front and back? How sensitive is a 36 Squirrel to tyre pressure? I remember a Kawasaki I had that was unrideable if tyre pressures deviated by a couple of psi.
I have read the article Martin sent with great interest and followed the advice from Stan taking things slowly. I think I found the spindles – particularly the top one nearest the handlebars – too tight as grease only flowed out when I slackened them off. There is a definite improvement but I would still like Brian’s view about the rating of the spring. However, one step at a time.
I have learnt a lot. Thank you to all club members who have helped me make sense of girder forks. My only real experience of forks prior to this was working on telescopics so this has been really useful. Particular thanks to Stan and Martin: I may be back in touch.
Thanks again: great club.
Wow! I am finding this discussion fascinating although I freely admit I’m out of my depth. I have tried to cover the points raised in correspondence so far and I’m starting to think that the linkages may be at least part of the problem. Thanks for the pointers Stan. One of them seemed a little stiff so I’ve tried to bed them in as much as possible without really knowing what ‘bedding in’ means. Spindles have been degreased and movement when pushed against front brake seems normal. What I could really do with is something like an exploded diagram with some indication of what would be a satisfactory set up. The point Brian raised about spring rating is a very interesting one. I have just refurbished the telescopic forks on my 1948 Ariel NG. First year of teles with no drain plugs and steel stanchions. I was struck by how much less robust the springs are compared to the Scott but of course there are two of them. But it was noticeable before I did the strip down to find a bit of treacle in each leg just how poor the suspension was. Stan is absolutely right: the fork oil seems to do much of the work and the bike is now transformed. I am starting to wonder if the improvement in the Ariel has coloured my perception of the Scott. However, I still believe that I have not got the set up on the Scott forks right and welcome all the help I get on this.
So,how about this for a theory. There is a problem with the linkages ( or spring rating) on the Scott but I had learned to live with it until refurbishing the forks on the Ariel forced the problem to the forefront of my mind by making for an unfavourable comparison. This combined with ever worsening road surfaces has demanded attention which I should have given it before. Plausible theory or psychobabble? I have really valued the thoughts of members so far and would welcome any further comments. The bike will be out on the road today or tomorrow and I’ll report back.
How interesting. You guys know some stuff. Just back from the garage and the spring measures 8.5mm on the calliper about halfway down its length. Will drag the bike out into the sunshine tomorrow to check the spindles as Stan suggested. Will report back on that. Thanks for all your help so far: I’ve learnt a lot.
Thanks for all the useful comments. I hadn’t considered bearings. As a matter of interest what would members recommend as tyre pressure back and front. I have to admit to be surprised when changing the front tyre pressure – mid 20s to 19 – didn’t seem to make a lot of difference. Perhaps my pressure gauge needs looking at!
