Ordered from motorcycle doctor. Put new gaskets in everything back together and fired right up. But saw bubbles between head and hug. Gonna take back apart and try resurfacing

did you check to make sure the cylinder head was not warped? if it was, then the head gasket will never seal correctly. Also keep in mind on the smoke, it will smoke for a bit if any coolant gets into the exhaust pipe, it takes a little bit to burn it out.  If you have the head off, check the surface to see if its 100% flat. any warping will cause a poor seal. Also check the cylinder to ensure its not warped as well. \

      2015 Massimo 550 Throttle Position Sensor issue
      By TexAcoon
      I'm looking to purchase a 2015 Massimo 550 that might have an issue with it's throttle position sensor.   
      From the fella selling this UTV, he claims its to set the idle on fuel injection because the engine will not stay idle or when it starts sometimes it idles too high.
      My Question if anyone had any issues with their Massimo 550 and if it was actually the TPS or something else that would allow the machine to idle correctly.
      Thanks!

      Losing Fuel / Prime 500cc
      By Buddee
      2010 Hisun 500 - Carbed'.  She sat for about 3 weeks since last use.  Couldn't get it started.... has spark but plug was not wet.  Bought new plug, cleaned the carb, confirmed fuel pump (pulse type) is working.  Still nothing.  Put gas in the plug hole.... started right up and idled as normal and drove perfect.  Used it for the rest of the day without issue.  Tried to start again next morning.... same problem.  Poured gas in plug hole again.... started up and best kind again.
      Anyone have any insight to what's going on?

      2017 Massimo MSU 500 top end kit
      By Jerrys500
      Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
      Thanks Jerr

      2021 hisun forge 250 no spark no fuel
      By vachi
      hi everyone i have this 2021 Hisun forge 250 that won't start. no spark no fuel.   when i turn the key on i dont hear the relays click or fuel pump come on. it does have power but the relay doesnt ground the pump or the ignition coil. dont know if there are any safety switches on this model or not.  it does crank and all the accessories work. i  hot wired the pump and it does work.  i found a wiring diagram but it's very hard to figure out and was hoping someone has seen this before. all fuses are good. thanks in advance.
