Peanut, people give information on an internet forum in a spirit of helpfulness and there has to a be a bit of give and take. No worries. Thank you for the offer on the carb slides, I'll have a think. The XS is not perfect but runs well enough that I have been able to take advantage of the present good weather to put a few more miles on it. In fact, gaining enough confidence that yesterday went all the way to Galashiels to show the completed bike to the welder who fixed the broken fin. The bike caused enough of a stir with his colleagues that I was almost dragged into the staff room - it was their afternoon break - where the banter then revolved around old bikes. Today, went up to this local beauty spot: Couple of spots, crows riding the thermals - the ground drops away down to the River Tweed, before rising again towards the volcanic Eildon Hills which dominate views in this part of the central Borders When we got home, pulled the plugs: I think that's a reasonable colour - they are café au lait in the middle and perhaps a wee bit too black around the rim? Comments from those with more experience very welcome. Long shadows demonstrate the low angle of the sun - as the year goes on, it will get much lower in these northern latitudes.
