Hi Beezageezauk
I do indeed have a set of plus 60s, low compression but as I thought there is a bit of scoring on the skirts, the bike was running fine with them in.
If you want I can post a picture, if you think you could use them then I would find out cost of postage, yours for postage cost and if they work ok send me what you think they are worth at a later date.
All the best - Bill ( I'm in North Northumberland )
