83 CR500, here begineth the lesson

I'm still none the wiser. Give us a link or a clue?

Best of luck, you'll have a blast. I like the idea of leaving new bikes in a haze of proper two stroke smoke ! The guy I was talking to also races new bikes at 40+, never stopped racing.
On the subject of jumps, last year I think, on a semi works 450 the same fella rode the infield MX at the F1 Grand Prix at Silverstone with a huuuuuuge tabletop. If you don't come out the corner before all balls you stand no chance of taking it in one, lap three... slight lapse and BANG. Lands 5 yards short, out for hours. Sells the new 450 the next day and swears enough is enough. This year has a twinshock 250 and another new 450 ride lined up!!! As a road racer I can kind of see it but really, theres only so many bones you can break !?

A still life from my box of shiny things for personal motivation purposes.

err white grips?? nooo...... blue cable.... again noooo but gunner gasser yes.. best thing for years...should be compulsory like ohlins and mikuni...

They are a bit like cartridge forks on modern bikes. They fit on to the damper rods and have a valve arrangement to restrict the flow of oil providing the damping effect. which is what the damper rods do. Problem with the damper rods is that the oil viscosity has quite a big impact especially when running higher weight oils. As the forks do work the oil heats up and its ability to "damp" reduces.

These give you an idea how they work....there was an article where Chuck Sun was trying them in his MAICO for Farleigh. I'll try and find it and post it up if I do.

Oh yes. Think 1980's BMX... You can't stop me

LOL, not sure I've seen white grips. Atleast not outside of the BMX realm, a long long time ago.....

Very interesting, something for the future maybe. As for now the kind of riding I do is mostly on a tarmac/loose surface/single track lane so no big impacts. Either braking or the front wheel in the air and no heavy cornering so I think I will rebush and spring and see how that works.
Soreley tempting though !

If your struggling for a 500 barrel and head i have one thats in good condition,got it in a job lot of Husky bike parts.

Thanks for the offer, got hold of a good 430 barrel,piston and head from the states at a good price which should be ok for now.

The first Red Cross parcel from HVA factory.


That should get me going. All the other bearings in tomororrow and should pick up the cases all finished.
Not only am I enjoying meeting people on here I get to meet some great people when I'm building bikes. Day off work today so picked up parcel, dropped hubs off at Dels for lacing up. 4.25x17 and 3.5x17 SMR pros ordered up in gold (thanks for the sizes Schimelaw). Dropped off shocks and yokes for more metallic blue with Dennis who has worked in what is really a shed since 1867 but does the most wonderful bike paint.
Off now to put another coat of paint on the KTM tank at a mates workshop and drink tea and talk shite. Then off to deliver crank to an engineering guru Mr G who does anything you can imagine in a small workshop and actually know more than God about engines.
Then home to sort out my nickel plating then I'm going to walk to the pub and drink Guinness until the wife comes to get me.
I know its not a competition but that to me is a pretty good day.

One gearbox question. There was a lot of end play on the main shaft and quite a witness mark (pic) from the sprocket bearing. I will find out what controls the end play when I do a dummy build or two on the cases and can see whats happening but any clues in advance? Should there be a thrust washer/spacer on that end bearing? One for Bengt or Bengt senior maybe..

I mean float rather than end play.

Yahoo, man, dig seeing those parts/goodies. Also glad to see HVA Factory finally got some decals made up. They look nice. I had been bugging them for quite a while to get some created. I'll likely be after some more stuff from them myself, in just a few weeks.

Looks like some important parts.

Couple of questions;

Is it normal to see that kind of porosity that I think I'm seeing on the rods beam area???? Can't say I've noticed porosity on any kind of rod before.

Also curious about the heat bluing, also on the rods beam area? Is that from straitening, or shortening the length, due to it being originally for another application. Just curious....

Really enjoying this thread. Very inspiring. I need to follow your lead, and get onto my bikes...

Questioned that myself. Just some scaling from forging and the blueing from the heat treatment on the rod ends. Also asked my crank man about polishing and peening the rod ends and beams but he say no. Waste of time and reckoned its good to go as is.
Learnt about silver plating and cage weight, inertia and rpm compared to crank rpm in big ends today. I hope I forget it in case it pushes something useful out of my brain and I forget how to walk. Interesting in a very geeky way though.

Mate,

The pics are very difficult to see. Can you re-posat them as full size ?

I'll pass them on the the old man. The '83 is getting a bit late for his knowledge, but the gearboxes on these old girls are almost all the same. I've been scouring the planet for a poxy thrust washer (part no. 842) on the main shaft of my '82 430. I did track one down in Belgium, but then found the same washer is used in the '79 390 Gearbox. I just happen to have a complete engine for on eof those lying under the bench awaiting a rebuild. I've just got to keep it quiet from my mate (who owns it) that I've nicked it....
I'll speak to the old man at the weekend and see if he can shed any light on your gearbox.

Knowledge from America has arrived ...

Very nice. I need to see if I have all of those I need, from here online. Seems to me I'm still in need of one or more service manuals.

You should get them by clicking on them, if not I will post again.

Seems like a good project i fancy road registering my XC 430 done this before with a Kwak 250 how did you go on getting a sertificate of newness i tryed but got nowhere ?? could you let me know how you did it if poss
