Turned out that the crack in the exhaust header was right round the circumference of it: it had broken away, where the headers siamese, so welding it would have been an arse-ache as you wouldn't be able to get the welding torch right round it. So new headers were definitely the way to go. I've had a closer look at the scuffed right-hand panel (the damage is really very small) and I'll touch it in as soon as I find the correct shade of grey paint. One of the mounting lugs on the panel is bust, but it's there still, so I'll refix that with a bit of glass fibre reinforcement on the inside. It really is super-clean for a 1993 bike. My local dealer, who did the headers (and also fitted a new front Gripster) said he'd had a lot of punters enquiring about it, and reckons he could have sold it several times. He asked one bod, who was crawling over it: "Would you give £1500 for it?" "Yeah, I think so...." "The bloke who owns it paid £660 for it on Ebay." (Expletives deleted) Once it was properly warmed up, it was evident that the tickover was a shade high, at about 1700rpm. Ever tried locating the tickover adjuster screw on a 660 Tenere, when the carbs are completely hidden behind the vast flanks of the petrol tank? I needed a torch, but thankfully it is easily accessible. It's just finding it in the first place that's the sod. The original toolkit is still in its cubbyhole, I discovered (to my pleasure). It now wears the old white Rickman topbox I removed from the XT600E before Donald started his short-lived ownership of it. And it is a glorious, wonderful hoot to ride. It's nimble, snappy, handles very well, stops well now the brand new front pads (fitted by the dealer who Ebay'd it) have bedded in. I've just filled the tank to the brim, and will be interested to see how far it goes on a tankful. My guess is 200 miles before reserve. Shame the seat looks and feels much the same as the 600E's, then.
