Please help I have a Massimo 400 buck that has an oil leak. The oil is leaking on the front side of the motor. It leaks out of a u-shaped steel pipe that has two banjo style fittings on it. I have tried using RTV and different banjo washers and have had no luck. It drips about one drip per second while it's running. I can't find parts for it at this time.

I take it the leak is at the fitting? Is it both fittings? Did you maybe try some plumber's tape? Wrap that around the threads on both fittings and see if that helps.

I have tried two sets of rubberized o-ring crush washers off of Amazon and both of them have leaked. Not sure what to do next other than to keep adding oil and keeping the dust down around the property, lol! Very frustrating.

I was able to get a closer look with a camera snake and I found that my leak is coming from the cylinder gasket and not the oil lines that I have been screwing with. Any ideas besides taking the motor apart to fix this(considering trading it in because of the lack of parts out there)

By "cylinder gasket" do you mean the head gasket? Keep in mind that these engines are usually a clone of another manufacturer, such as Yamaha, Kawasaki, etc. If you do some research you may be able to find out what other manufacturers out there are using an identical engine. This can lead to parts that you originally thought were no longer available.

I'm sure other members here can chime in and offer some help with that.

      2021 Massimo T-Boss 410 CV Axle Boot
      By Rider
      I have a 2021 Massimo T-Boss 410 and it needs the cv boots replaced.  Has anyone had to replace the boots on their T-Boss?  Does anyone know where to get replacement boots?  Are there boots for other ATV/UTVs that will fit?  The Massimo parts site only sells the entire axles.  Thanks

      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...

      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

      Coleman UT 400 Garage?
      By Homeowner A
      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?

      Is there a better performing higher volume injector than what they come with or what is the best replacement for the original?
