did you figure out why your viton seals leaked?
Nothing definitive, but I reckon being stored dry in a garage that was a freezer in winter and a sauna in summer probably didn't do them any good. Most likely the gasket goo I put in there though!

Thanks for the pics, your shop is looking good. nice job on the sprocket! I would just add I thought the extension on the shifter is a bit sketchy I would add a nut on the backside of the bolt to lock it down.
There is a nyloc nut on the back of it, just can't see it very well in the picture
So I've been busy with the bike when I've not been busy doing jobs round the house for the wife
I've also booked a track evening at cadwell for August, so I need to get this running right! (track days don't half book up quick now!)
Out with the front wheel.
And out with the forks.
These S hooks I got ages ago keep coming in handy, keeping the tension off the brake lines.
And into the vice. Damper bolt at the bottom loosened first, then the top nut, top nut taken off by loosening the nut underneath it, pull out the damper bolt and damper (making sure I don't get oil everywhere), then the spring and drain the oil into a pan. Prise out the dust seal, ping out the circlip and slide hammer the oil seal out the way!
The oil was minging. And this has been in about 6 years, two of those unused. Hate to think what forks that have never had an oil change are like
All stripped, cleaned and inspected, upper and lower bushes still in good condition, nothing looking worn.
I did find this little nick in one of the stanchions, dealt with by taking the raised part and any sharp bits using some wet and dry with wd40.
After never having a proper oil seal installation tool, improvising with tape wrapped punches etc, I thought I'd make one out of a lump of brass I got out of workshops scrap bin.
I made it so it seats the upper bushing and the oil seal without damaging anything. Plenty of weight in it so it's like a slide hammer.
Back in with the circlip and the push in the oil seal.
Stick the damper back in and torque up the bolt.
While filling with oil, pull the damper rod up and let it drop down bleeding oil through it.
Topped up with oil and excess removed to correct fill height using a syringe, easier than measuring!
Washers, spacers and nut stuck back on.
And back on with the top nut.
Repeat for the other one and there's two refreshed forks.
Stick the forks back in, torque up the triples and then the top nut, dial back in the settings and job done!
Onto the brakes. They only needed a good clean and new fluid, nice and easy.
Still have to balance the carbs, angle the handlebars correctly, tidy up the reg rec spacers and give everything a good once over
