Thanks for that Martin. Those 392 piston's are a little difficult when it comes to finding ring's. If you have any idea who is doing rings for those i would be interested. Cheers

[UK Pete]

I thought they took the same rings as the f2

Same rings as the F2 pete but, hard to find at the right price.

I got some standard size ones from Davis Silver for my F1 that had same pistons. They were £76 plus vat and P&P for full set, though

Made by NPR and listed as OEM  13011392004P

Thats the ones they fit k7 and f2, the k8 is virtually the same as k7 so makes it easier when searching for parts
only problem with the rings is they only seem top do standard size

Too rich for me. DSS is well over priced these days. Just did a price check on 10 items from DSS and compared the same items with a German dealer that i use. The result was DSS was £83 more expensive.

DSS has all ways been more than most got to pay for the USA warehouse

Just realised I forgot to drop off the handle bar clamps   

The seat pan needs alot of work as cracked and rusted through

Front brake caliper was the usual pain

First the bleed nipple was seized, took lots of heating and soaking over 2 days, find a deep 8mm socket is good used with 1/4 drive ratchet to get a better feel and hopefully not snap nipple.

Feels a bit like playing Russian roulette getting these out

Once that was out, had to refit to try air pressure to push out piston.

Would not move, but managed to push piston in a bit but would not come out with air pressure, soaked with WD40 for a couple of days.

Eventually used the grease gun method, using an adaptor with grease nipple and pumped in grease.

Came out fine.
