My Guzzi gearbox problem turned out to be a loose linkage. Tokk slightly longer to fix that expected: I had to unbolt the starter motor to get at the screw. Next job: the bike's steering had been getting a bit... odd, and it dawned on me that I've no recollection of ever greasing that particular bike's head bearings. Whoops. Got the steering apart and they were indeed dry and the bottom rollers were beginning to corrode. I just caught it in time. All well now. It's funny how these jobs seem to come in batches: I've only recently done the R1 because I needed to adjust the bearings; as this entails taking the top yoke off I figured it would be daft not to grease them at the same time. And Off Topic: I'd managed to crash both my model helicopters last week. The indoor Sabre had lost a rotor-head bearing when I crashed it in the garden: it suddenly spun 180 degrees and rolled and I got disorientated. The other, an Eco-8, suffered a bent tailboom because I was trying to teach myself to hover it nose-in and let it drift too close to the shed. I fixed both today. I might start using a tether and anchor plate while I get the nose-in hover sorted.
