Good to see you have your sense of humour back. :plainsmile Lets hope you don't have any badly seized bolts otherwise heat and big hammer may be required.

I've decided to get the fork lowers powder coated by http://www.classic-coatings.co.uk/ I took the parts to show them exactly where to coat and where not too, he quoted me £30 for the pair in matt black :thumbup:
Should be done by next wednesday will post some pics :)
Before:

Old fork lowers finished in tatty silver paint.

After:

I was very pleased with the finish of the powdercoating he got the top edge exactly how i wanted it.

Image
Heres the stock progressive, as you can see it appears to be made out of an old coat hanger and also needs a 100mm spacer! Its no wonder they bottom out so easily!

Image
The hyper-pro progressive springs have a more forged look to them and are the full 410mm in length and require no spacer.

Image
Nearly done, rebuilt with hyper-pro progressive springs new seals and hyper-pro 7.5w fork oil. My facebook friends will know I had some trouble with the damper hex bolt but it was sorted with help of a friend and an air impact wrench.

Image
back on the bike they look great.

I sprayed them at first but it didn't hold, well, I spilt brake fluid on them :eek2 I ended up getting some off some later model forks which are anodised. :biggrin

I have a pr of Yacugar progressive springs (pretty much indentical to Hyperpro) for sale if your still thinking about taking the plunge, see For sale section, or PM me for details,
in a nut shell linear springs are best for racing, trackdays and v fast road riding where the roads are smooth and in good condition (prefrebly with no speed limits), think Isle of Man mountain course, but linears need to be rated to suit your weight and require more accurate setup plus they are less forgiving on rough / uneven rods. while progressives are more of a compromise, and less sensitive body weight , setup, road conditions etc and while not as precise as a well setup and matched pr of linear springs they are a massive improfement over OE, I had them fitted with the recommended 7.5wt oil, 140mm air gap and the taper suspension mods I was very pleased with the result.
I've now gone all European and bought a KTM Superduke GT and Aprilia RSV1000R :D ,
Storm is now gone :cry: .

Dear Cybercarl,
I have read your article and was wondering would these mods ie drilling the 1mm hole in the cartridge and grinding the taper shoulder off the damping rod as well as using 10wt oil make any difference without changing the springs?

Regards

Carl's not been around for a while .
Why don't you want to change the springs ?
While you have the forks apart you might as well go the hole hog .
New seals,bushes,springs,oil .
Or just send them to Roger and get them done correctly by the man who came up with this mod .
