Would there be much benefit if I took my 650 commando pipe and instead of it going into one pipe and then to muffler, i ran 2 pipes to 2 mufflers. Or is the y-pipe helping pull exhaust from the other cylinder.

I think the 2-into-1 has some benefit in torque. These little motors are sorely lacking in that, so anything you can do will help.

      Top speed is 30mph on flat grass ground.  but it will not go up minor hills forward or reverse without a runing start.  If you start at the bottom of the hill machine will stop about 1/2 way up.  I have the engine cover off and you can see the outside of the drive clutch will stop spining., and the engine does bogg down some.  Dosent matter if engine is cold or warmed up.  Seat belts are connected.  Fuel is clean
      I am the 5th shop to look at it and different shops have replaced the fuel pump, injector, ign coil, wet clutch, 
      I am not sure how to check for codes with this machine,  can anyone teall me how to do it?
       
      Compression with hot eng is 145,  valves adjusted to .005 with a cold engine.  Dash shows 426 hours
      I am not convinced it's an engine problem

      Recently I had an overheating issue on my 2022 Coleman Outfitter 550 (Hisun UT550) and to check to make sure it was fixed I took it out for a ride around the block. After a couple cycles on the LED coolant meter, I took it for a couple mile ride and on my way back I heard a loud metallic snap then a grinding noise. It was still able to move under its own power but very slowly. I was about 2 blocks from the truck so 'I limped it home and up onto the trailer. I know I need to tear it apart and look for what broke, but anyone have a guess as to where to start? I'm seriously getting tired of this damn machine! 750 miles on it and already replaced the belt, wet clutch, primary clutch, clutch roller weights among a few other things. Seriously, this friggin machine has spent more time on the lift than on the road. I thought I bought this new because it was from the owner of a tractor supply, but he registered it under the stores name making me the 2nd owner voiding any and all warranties.
      Any Ideas what to look for would be appreciated.
      Thanks
