Question? I've got a couple of Choppers. My 98 has 3,500 hours on it. I follow a good maintance schedual, so far I've replaced 2 belts and one spindle bearing. Question is how many hours can a guy expect an engine to last before rebuilding. I dont want down time and am reluctant to take the hit on a new machine but a Kohler maint. rep. told me today he has heard of guys getting 2,000 hrs. before an overhall is necessary. Thats about 1,500 hours ago for me! The machine runs good great cut-as good as my 2001. By the way it's an XW-2200/60. Any experence firstname.lastname@example.org or this form.
