Hey folks. I can't seem to switch gears on my k75. It sounds like it shifts up to Neutral, but I can't shift anywhere above it. Feels like its locked up. Clutch seems be engaging fine, and I've spun the rear wheel but no help. I'm new to the K bikes, so hope this isn't a stupid question, but does it need to be on for the transmission to shift? Just trying to figure out the issue before I start working through other aspects of the bike.
