Got round to servicing my Tuono. New oil & filter, new air filter, new 180-section back tyre, balanced throttles[1]. Took it for a brief shakedown and it was definitely smoother and just nicer. Still not certain about any improvement from the tyre becuase it was only a few miles but it *seems* to have made the steering slightly more neutral, which is good. It's not a bad bike for doing routine servicing at all. Now I just have to wade through the manual to find out how to turn off the 'Service' annunciator in the dash. [1] I cheated on this: just stuck on a pair of vac gauges and twiddled the two air screws. The proper procedure seems to involve iterative twiddling of air screws, throttle screws, taking CO readings, etc. and my CO meter really isn't up to it. Also, ICBA.
