Welcome to Quadcrazy. I have seen the same problem with a Chinese 110 bike.  I’m not sure why but I have a question.  

Same situation when rolling it etc. I started the bike against a wall so it would not go anywhere and let it run for 10 minutes. After it ran for that 10 minutes and shut it off the bike was fine to roll. And it was that way for a few days. After that the same thing happened.    

My guess was that the oil in the engine makes the clutch plates swell up with oil from sitting causing the problem and clear up once things are spinning and centrifugal force spins out some of the soaked plates. Maybe a design flaw or poor clutch plate material (cheap) stuff maybe ?   Sounds crazy but that’s my guess.  

My question is have you ran the bike for a while and seen a change. If not try what I said and let me know.  Never solved the problem other then starting the bike every few days but that’s a little nuts.

I take it as a feature, really easy to push start this way. 😊 Especially when the battery dies, or the switches just stop working for no reason other than the fact that it's cheap.

Had a 2007 110cc Chinese atv with the same problem. Went through a few different clutches over the years and, even when they were worn out to the point where it couldn't make it up the smallest hills, it would still grip like no tomorrow when off.

If I wanted to move it, I would just start it and let it idle while I pushed it around, or just picked up the back.

      Hi all. I have a timberwolf 250 2nd that will not start.. I thought it was out of time bc the guy I got it from said it just quit on him. The tensioner had a nut welded to it and it was like2 teeth off. I installed new tensioner and chain and it still will not start. It has fire and it will not hit off brake cleaner. It has compression. Haven't put a gauge but I'm sure it will crank and run with what it has. I double checked my work and it's still in time. Spot on. Both valves move. I'm about to put a feeler gauge on them and I'll cone back but other than that any ideas?

      Looking for two stock front wheels for 92 TRX300 2WD.   I think they are 6 x11" size.

      on my honda trx 500 we have no power to the ignition switch for starting or ignition
      we have lights and horn working
      all fuses are fine
      have traced through the harness and cant find any broken wires or bad connections
      from what we have gathered so far the pgm fi unit is not sending any power to the fuel pump relay to power everything up.
      if we put power direct to the ignition switch plug then everything works but wth the key in the off position.
      does this sound like a faulty pgm fi unit?

      Hey everyone,
      I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
      Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!
