2018 Massimo 500

Recommended Posts


I purchased a 500 with 100 miles owner didn't use like wanted.  I have been using (live in Michigan) just started getting cold and now i am having a stalling issue all the time.  The unit start runs great but when come to a stop it normally stalls, and when give it power it can bog at times.  I know there are the obvious plugs, fuel filter etc but all seem ok, figured there might be a trick tip to this before i dive in.

2. When i take the center cover off there is a pipe that is not covered?  what is that for ?  should it have been covered?

Not sure it weather is connected i let it warm up but usually have to hold pedal down.  Ran perfect since i bought it and now acting up


Thank you in advance

Here is the part itself.

It should be located around the intake into The engine. I'll do some more looking.
