Put a 999 away for the winter last year and had it on a trickle charger. Ran fine when I put it away and it started right up when I took it out. But as soon as I click it down into first the bike shuts off. Does the same thing if I go up to second instead. Clutch is pulled in and as soon as I click into gear it shuts off. Clutch seems to be engaging fine...any ideas? There are no error codes or anything like that on the instrument screen. Runs, idles, everything seems fine except for that.
