Will a PW50 clutch start to slip if it is ridden for long periods of time at low speeds/ small throttle openings? Kind of like constantly slipping the clutch on a big bike? My kid was putting around the property this weekend and after 20 minutes or so the bike sounded kind of weird and he was having a hard time getting up small inclines. We let it cool down and he rode it again later in the day and after a bit the same thing happened?The clutch area seemed hot. I parked it at the end of the day after it cooled down again and rode it into the garage w/o issue and I am 200lbs. Is this an issue with these bikes, a worn out clutch or does they boy have to get on the gas a bit more?
