My 11 Hammer is starting to worry me a little. If I get on it hard in 2nd gear it feels like the drive belt is slipping. It only happens for a split second and continues to accelerate like normal. I was convinced the belt was slipping the first time it happened and checked my belt. It was a little loose so I adjusted it. But it's still happening. I'm getting concerned because the bike is always in 2nd when it happens and has never done it in any other gear. Don't think its the clutch because in my experience clutches tend to slip in higher gears. It almost feels like the trans gears are slipping only to reengage when I back out of the throttle a little. My bike has always sucked on 1 2 upshifts and I always have to make sure to hit the lever firm or sometimes I get an embarrassing neutral when taking off hard. Bike has 22k on it now.
