the ignition switch on my SV650 is getting desperately difficult to operate - I have to jiggle and JIGGLE and j-i-g-g-l-e- before the key will turn on . off is a little easier, but not 'easy'. obviously, there is either a lot of wear, or the tumblers are gunked up. I've got 67,000 km on the bike, and it lives outside (altho under a cover) so I suppose the former is possible, but this eeems like 'low miles' for a tumbler failure. I lube the tumbler fairly regularly using 3 in 1 oil.
