I don’t know about simple, I’ve worked on everything from hockey choppers to nuclear reactors, I’ve been able to work on my 2007 foreman 500 4x4 es, but only with the help of some great people here on Quad Crazy. You can’t just jump in there not having a background in quad repair. The people on Quad crazy make it possible to get the job done. But you are right they are tough long lasting machines. Ride On!!
