My 2015 CCT has a new problem since I put in a new starter and the torque limiting clutch (part number 3234256). These parts were changed due to a loud squealing noise when starting the bike on cold mornings. The battery is the original but tested good at an auto center. The terminals are clean and tight. Sometimes when I push the starter button the motor is slow to turn over. Sometimes it will turn over slow, then stop spinning totally and then turn over normal until the motor fires. Other times it spins normal and fires right up. It has 45,000 miles. This problem only started to happened after I changed out the parts. I will probably get a new battery just to rule it out and they don’t last forever.
