77 WR250 back from the dead

Those shock bushings were original. The original Girlings were replaced with curnutts soon after I bought the bike.

BTW, while I was looking around Ebay I came across these NOS springs. Thought you could use them for color reference.

Great find but $99.99 for the starting bid seems high.
They are the same as mine. the part number stamped into my shocks is 70053005A CJ27.
They don't look so great for NOS.
I'd like to change my bushings but I most likely will upgrade to Works Performance shocks when I get more $$.
Meanwhile I'm repainting the Girlings.
They are surprisingly not worn out and operate as they should according to the Husky workshop manual.

I found a paint color that almost exactly matches Girling red.
Dupli-Color Chevrolet orange-red DE1607.

Nice. I have a set of museum quality original girlings and the red coils do look orange-ish. If you really want it authentic, the black springs had a few sloppy blue paint streaks to mark them as standard weight.

I didn't do the stripe because IDK which weight springs they are.
Now I have to figure how to compress the spring without damaging the new paint for reassembly.
I also would like new bushings but they seem unavailable.

Rich, measure the i.d and width of your shock eyes. Post it up here. There will be something that will fit.

Ok the width is about 24.5mm the ID is about 10mm. The ID of the shock is about 23.5mm. The width of the shock is about 17mm.
As you can see it has shoulders that extend to the OD of the shock.

Is the 10mm I.D. with the steel sleeve fitted ? The bolt should be an M8. Has someone drilled the frame and arm out to 10mm ?
From memory they seem close to the Hagon's. Mine are on a bike at the back of 2 other bikes. I will see if I can get in there to check.

I have no idea if they were drilled at some point but according to the parts manual yes they should be 8mm.
My bolts are 10mm and the sleeves in the bushings are also.
I did improvise a cheap easy spring compressor

Check the vintage husky parts site in UK, I know they have those large rubber bushings for the ohlins that look very similar. I would bet a million jap bikes used a similar bushing too.

Different subject, my bike didn't come with a chain. What size/length should it have?
I assume it's 520.

I emailed them. Thanks

Just get a 120 linker and cut to size.

As to size...
My 79, 85, 86 use a 520 chain. I'm not 100% on the 77, but if you look, the parts manual should list a size (it might be an English size, but if you Google it, you can find a chain size comparison chart pretty easily).
120 link and removing links is a good approach. Also, get a master link if you don't have one. While it's possible to use a one-timer link, I'm not sure why people do.

Yes it takes 5/20 I have an non O ring on my 78 250CR but I think you may be able to run O ring on it,but I would check to see if it will fit through the chain guides I run a standard master link on all my dirt bikes.

A standard width o-ring chain did not fit through my '77CR or '78WR chain guide, but the narrow o-ring version from DID fit.

from DID did fit???

Yes, the narrow oring from DID did fit. (search DID narrow oring)
