Has anyone ever had a Massimo 400 Buck that overheats and the antifreeze blows out of the motor everywhere?  I don’t think the fan is turning to cool the motor.  Any ideas how to fix this?

      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

      I have a Coleman UTV 400 and looking for something to store it in.  Preferably something vinyl or plastic with its own base that can stand alone outside and house the UTV.  I think the dimensions of the UT400 are around 106" long 52" wide and 74" tall. 
      What should I consider that won't break the bank?

      We have a 2018 Cub Cadet Challenger 400 and I found this Internally Threaded Bolt with a 10mm head size laying in the floor of the shop bay here on our ranch where we park the Cub Cadet.
      Trying to figure out where it belongs...

      Hopefully someone else will buy a UT10X and join in.

      the regen braking on my e1 has stopped working unless (for eg) I am going down a hill in low and it's slowing things down to stick to the 10kph limit. when I drive and take my foot off the accelerator it's not initiating the regen to slow things down and instead just coasts at whatever speed it is at, or speeds up as the regen is not limiting it. the brake lights work, so it's probably not a fault with the sensor on the brake pedal
       
      hoping someone else might be able to provide some suggestions on things to check, as the mob that I bought it off seem to have gone silent on me
