Can anyone help me figure out where I can find a piston, rings and clips for a Massimo Buck 400? I have contacted Parts Boss, Cazador Motor Sports and motorcycle doctor and non of them can help me. Part number is 1MQ1163100 any help is appricated.

I believe Hisun but I cannot find manufacturer on manual or on engine. Learned a lesson. Don't buy Chinese UTV's. found out the hard way. May be assembled in Dallas TX. but parts are from China. Thanks for the website!

I have taken my engine out and am doing a complete rebuild due to issues I had with piston. Since I had to get that deep into it I decided to change ALL gaskets as well as piston and piston rings. Now I am having an issue finding the right parts. Called Parts Boss for help but they keep telling me someone will call me back, but no one does. Can anyone point me into the right direction to find someone who can supply all the gaskets, rings and piston for a 2020 Massimo Buck 400 EFI? I called Massimo but they no longer stock parts for this UTV. Need help! Thanks Jon

60 PSI. I am going to look at spark plug again, fuel injector and take off the cam cover to see if anything looks odd. If I don't see anything then I believe I will run a top end leak down. I hope that I can find the issue but afraid it is the piston and that will be an issue. Afraid if I take engine apart I will not find the parts I need to fix due to being manufactured in China. Lesson learned for me. any suggestions are welcomed. Thanks

I was riding my Buck 400 and when going up a slight incline I noticed it dropped in power. Once I reached the top I made a turn and it stalled out. I have not been able to start it. When I looked at air filter the case was about 2 1/2 inches deep in oil and gas and filter was torn. I cleaned it out, replaced spark plug and drained oil. I added leak stop then new oil. It just had head gaskets replaced back in the fall. When I try to crank it, it sounds like it wants to start but it is not getting enough to start up. Does anyone know what could be happening with this UTV? I am stumped! I figured there is a bad seal for the gas/oil mixture to be in reservoir where air filter is. Hopefully leak stop additive will correct that for the time being until I can figure out what is happening. Please help. Thanks in Advance for your feedback.

Thanks. After more research found it was a bad battery cable.

My Massimo 400 buck started blowing white smoke out of the muffler. Anyone tell me what is creating that. I immediately parked it and afraid to crank it until I know what to fix. Please help if you know. Thanks

I have changed spark plug, starter solenoid relay and battery. It has power but will not crank. Just a click and nothing else. Lights and dash come on. What is it I am missing? Need help. Thanks.
