The only problem is that the cruise operation is unsmooth. I mean everything works fine, it basically holds the correct speed, cuts off while braking, resumes when I push the lever and everything but in order to hold the speed the CC continously engages and disengages for a second or so which causes an unsmooth, uncomfortable ride.
what should I do next? speedo cable? speed sensor? throttle lube?
or is it the amp and I have to resolder again?
