And the IAT sensor it is; code 15. Thanks very much, one and all. I'll give it a good squirt with aerosol contact cleaner later; that should sort it. Woo Hoo.....
It's nice; it's very nice. I'm only getting just over 50 miles to the (UK) gallon, though, and that's not thrashing it, but I'm 6 ft 1 in and mass about 270 pounds in full riding gear, with the aerodynamics to match, so maybe that's not surprising! Don't care, anyway; running costs are not a factor.
Cooter, re the belt position, mine's the opposite; it's snug against the inner flange after pushing it backwards.
Still no advice on whether a headstock (I think you call them triple tree) stand or a front paddock stand is better for maintenance? SOMEBODY must have an opinion, surely? (Or if not Shirley, somebody else...)
Take a close look at your idler pulley. Is it wearing the coating off unevenly? Perhaps you need idler bearings SKF6203-2RS or even read wheel bearings or swing arm pivots? Hard to say, there really isn't much to go out of alignment in the system.
Front stand is a matter of preference, but I prefer the triple tree stand for front wheel and fork removal.
