I used this spring hook. I had to wear a thick glove to protect my fingers. It's not a easy job though

Your spring has the two short sides?
On the Part list, there is a long side and a short and the short side is mounted to the top of the Crescent of inking?
Early spring had both sides short?
However Mark Remove me a doubt... Clearance of brake is not mounted upside?? Because there as it is mounted if you press the brake pedal tie-rod will go back and do the opposite effect...

That's exactly what I have used in the past and you're right it's not easy.

My spring has a long and short end.  This shows in the picture of the spring laying on the bench.  If you look close the short end is on the "C" plate and the long end is on the hook on the center stand.

However Mark Remove me a doubt... Clearance of brake is not mounted upside?? Because there as it is mounted if you press the brake pedal tie-rod will go back and do the opposite effect...
I see what you mean about the brake shaft.  It might look like it is installed wrong but I have the brake rod zip tied up on the frame to keep it out of the way which made the arm drop down like you see it.  You are very observant.  I appreciate you guys paying such close attention.

There, I understand better with photography, I knew a bit there's something odd in the rod brake with the position of the stand...
And it is true that this spring is really the devil getting has the hook without damaging the beautiful painting!

Still busy but I have managed to whittle away at a few things: oil tank, swing arm, center stand, shocks….


…chain guard, ignition switch, side stand and battery box.  But of course not without issues.  The worst one was dropping the battery box.  I still don’t know how that happened.  And of course it had to bounce, and I tried to break its fall with my foot and managed to kick it across the floor.  I think it was chipped on all 8 corners.  ???


But a trip back to the painter and it’s as good as new.  ;) You can’t see it in this picture but I still need to find a decent, correct starter relay.


This is where it’s fun to make sure all the hex heads are correct.  No 8 on the shock, regular 8 on the chain guard…


….offset 8 on the chain adjuster.stopper.  :D

Noticed a couple of things I would like to query...
Are the rear shock lower mount bolts chrome or BZP finish - I'm not sure from the pictures, and have only previously encountered chrome finish here?
Washers under the offset "8" bolts in the ends of the swing arm? None of the (believed to be) original bikes I've come accross had washers fitted here.
Then again, I've never had such an early VIN.

Good to see those offset "8" bolts. #302 and #1120 also had these in the mainstand pivot clamps, and the ignition switch bracket.

Looking really great; its going to be one of the best.

Chris,
The lower shock bolts are chrome.  
I checked on the washers on the chain adjuster stoppers and you are correct, they are not used there.  They are not in the parts book and not in my notes.  I don't know why I put them on.  :o  ::)  I must pay closer attention.  Thanks for catching that.  I appreciate the input that you guys have.  ;D
I think 302 is plenty early.  There can't be too many differences from 97.

This is starting to take shape... It is very good clean work as I like it is done... ;)
There is no washer with the screws of the stops it just seems to me memory...

Yes after looking at it I realized they would interfere with the chain adjusters so I would have caught it.

As long as we are talking about washers, as I was checking my notes, I noticed something that I am questioning.  I show that the M10 washers on the screws that clamp the steering stem to the fork tubes are chrome.  Can anyone confirm that?  They are a special small size outside diameter of 18mm and according to my records they are the only two of that size on the bike.  Because of their location and the fact that the screws aren't chrome it seems odd that they would be chrome but the fact that I noted it seems too deliberate.

First off, Mark, how exciting this is to see your gorgeous build come together.   How great of you to take the additional time to take pictures, post them.  Thank you !

because i'm not sure what you are referring to and i don't want to create unnecessary confusion, i hate to risk saying my opinion, .... but i'll give it a stab....

only 10 mm bolts i can think of, thread in to the lower clamp that's part of steering stem.  as i recall, those are plain washers (pn 94102-1000) and are bright zinc....  (the RH bolt also fixes the stamped guide for the speedo cable.  the washer is on top of the guide.)

Thanks Steve.

Yes those are the ones I'm referring to.  Makes sense that they would be zinc.  Have others seen zinc too?

Yes, I also confirm... I have two new washers a very old stock and they are well galvanised as the two 10mm bolts that tighten the fork tubes.

I assembled the fork bottoms and completed the forks.


They’re ready to put on the frame.  It sure is nice to have pristine fork assemblies.  They look like brand new.  ;D


I got my painting back too.  Looks great.  Now I can start to see some color.


Except for my control housings and master cylinder (more to come on that) I think the rest of the parts are all painted, plated, polished and otherwise ready to assemble.  In theory it should go pretty fast at this point.  I still have to get tires, battery, chain, etc. but I just might be starting to see a light at the end of the tunnel.  ;D
