Amazingly i found this
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=300469369432&ssPageName=STRK:MEWAX:IT . I emailed jackscycle requesting a transatlantic trade, but they didn't reply. These cylinders are rare here in the UK,
the same goes for WR & XC parts, very hard to find. It's a shame there is no year on year top end interchangeability with the 1986 250 cc bikes! I am the same as you Dirtaddict, if a rare part comes up it is worth trying to obtain it, even if it is on another continent LOL!

I will at some point get stuck, so Photoguy, thanks for the offer mate, I will be in touch! nice one...
I got the frame and shock spring back from the powder coaters and I am pleased with the end result
The shock went to a guy who makes a living tweaking road racing legend John McGuiness's factory backed Honda superbike. He works for HRC (UK) HM Plant Honda so he knows his rebound from his compression and all that**************************************** He sent it off to a uk importer of everthing Ohlins to get an accurate match of the internals. Anyway, the shock has been rebuilt with new guts, revalved and regassed and now should perform just as Husqvarna had intended.
This is a big difference from the day I got the bike, as you can see from the first photo of the bike, the bike sits low at the rear end doesn't it? Well, this is because the bike had absolutely zero sag at the shock and had worn out needle bearings at both the sides of the swingarm and at the shock linkage, not lick of grease in sight!. The bike would be almost impossible to ride over rough terrain in this condition, never mind getting any power down! All bearings have been exchanged for fresh items and now rotate freely. I couldn't find the original FAG bearings with grease orifice in the closed cup shell, so went for 8 bearings instead of the designed 4, thus allowing clearance between the bearing shells for grease ingress. Works a treat...
Unforntunately lack of maintenance has led to the chain eating the underside of the swing arm close to the pivot point, I don't really want to have to weld it but is has gone right the way through and made a small hole.
Anyway, I am going to carry on with her. I have been in touch with Rich Daly at Dynoport in the US and got one of his revered ceramic expansion chambers on order! Not the purist's cup of tea I know but thought the bike deserved a bit of BLING

I did offer this work to some of british pipe builders but never had a response

So thanks too Dynoport, top stuff!!!
