Happy days :)

Forks are back from Philpotts and I can put them back together again and get a rolling chassis together at long last. Will make things easier in the shed as I will be able to move the thing about a bit!

SumpMagnet:
After initial paranoia about the forks and the fit, it's another excellent job by Philpotts. Threads all perfect and nicely fitting and everything dimensionally perfect.

So, with the forks here, it was time to build them up.

First task was to find the other parts, the fork lowers were easy, and the springs/dampers had all been carefully threaded onto wire loops and wrapped in rags so all the bits were in the right order. The fork springs didn't look like they were wound differently...but I still wanted to make sure they went back the same way round they came out. I wasted 5 minutes looking for some shims to go on top of the seals between the spring clips...until I checked the parts list...and these don't have them. Which explained why I couldn;t locate any. Most forks I have rebuilt have...or is it just a Kawasaki thing?

Anyway.....



So, found a lovely large impact socket for a drift ( no I dea what I bought it for...but it fitted something somewhere that I really needed..... ) and tapped in the seals. The well for the seals was deeper than the seals themselves.....so I tapped them in to just below the clip groove, and measured both to make sure they were the same. I wanted them to sit just under the clip and in line with the lower edge of the groove. I figured if I was meant to tap them all the way in....I could always go back and do it....but getting the seals out would probably mean mean new seals..... Having once fitted one upside down....I found out the hard way that just about every tool capable of loosening the grip of a seal wrecks it.



New clips went in easy. The old clips came out in pieces....

A little wipe of oil on the seals, dampers inserted...and the legs slid home sweetly. Dust caps were gently tapped home with a rubber mallet, and the process repeated for the second leg.

Now...to tighten up the damper bolts I need to compress the springs and screw in the caps. Then it's easy to nip up the damper bolt. Don;t want to fit the legs until I can drop the wheels in...and that really wants the dampers done up. Not sure if new copper washers are necessary...but I gave mine an anneal on the stove and will see if they are oil tight. They didn;t look dished or distorted....but if I need to, it will be done.



So just fill up with the right fork oil ....er..... fork oil. You did buy some fork oil right? Bother.

So...when I buy some fork oil, I will finish this off and pop the front wheel back in. Any recommendation on fork oils? Book says 10w .....

K2-K6:
Nice work there,  always good to build up things with well prepared components too.

I'm using Motul fork oil across different types of fork as it works well, bought via internet for availability and price. Mostly use 7.5 viscosity.

Auto transmission fluid is fine though,  but ordinarily rated at 5 viscosity which may feel a bit thin on this bike.  Certainly wouldn't initially go above 10 viscosity unless you identified genuine need as that usually stiffens them too much and they "bob" rather than move in a more supple way over stutter bumps.

Spitfire:
Looks good, it's really nice to put things together with all the nice bits to hand, certainly better than bashing them apart.

Well...the project is on a bit of a hiatus, as I am trying to move house...and that is a thing of terror.

On the plus side...one of hte reasons I wantr to move house is because I have a small and overcrowded shed, with no access to the road. So if I build hte bike were it is....well...it would have to come aparrt again and be carried through the house!

The new place which I hope to buy (offer accepted....and same on my current place) has a garage. A proper one. All the space I will ever need. It's a super-mancave, and is this mans dream setup.
The bikes will have a dry and secure place to live, and there is even a house attached to the garage for the mrs.

If all goes well, progress will go a lot smoother as I will have room to spare!
