PW50 Clutch Question

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? 

check the oil, and when was the last oil change?


and its possible you need to replace the clutch.

There is a site called it has lots of technical information. The QT 50 and PW 50 engines are basically the same aside from a lighting coil and lower gearing.

      Hey guys, I just picked up a running 03 yz125 a few weeks ago and upon tearing down the top end, I noticed the cylinder head looks a little beat up. Is it possible to just clean it up or am I better off just buying a new one? Thanks guys.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      Hey guys, 
      I've used this forum as a "guest" for awhile now and I thought I'd share my build now that it's all coming together.  The primary purpose of this project is to help me train for roadracing my 2009 R1 at lower speeds as well as giving me a cheap alternative to racing the big bike. 
      Here's what she looked like when I picked it up from a local shop.  Paid $800 cash for the bike as you see it with 17' rims, FMF pipe, EBC 250mm front rotor and clip on handle bars.

      Fits PERFECT!

      Shake down run at the Herrin Compound last summer:

      As she sits today:

      i bought my yz125 from a dealer and they said that the clutch was broken so i bought it and it worked fine it would run move and everything and then it started to act up and now only first gear works barely though. when you put it in first it acts like its bogging down but its not and when you go into gears 2-5 it wont move i dont know whats wrong with it im assuming the clutch is slipping or something if you know please leave me a comment
