I have a 1971 suzuki 90 enduro that seems to not be catching gears. I was riding down the road when it slowed down to a stop. When i crank it up(which it does easily) and try to go into first or any other gear it doesnt move but it also doesn't stall out when i release the clutch. I can hear the clicking when I change gears and dont know how to fix it. Please Help!
