97 mxz 670 longer track - Snowmobile Forum: Your #1 Snowmobile Forum

I put a 144 track under my mxz, it came stock with a 121, does anyone no what changes should be made to the clutching? The gearing has been lowered but I haven't done anything to the clutch yet. I am trying to get that snap back..

Thanks in advance

A heavier spring will raise the engagement rpm's. Check an application chart for specifics.

your loading more now, its going to be an experiment, get close by finding the clutching for long tracks of that year, what the summits were ect. then start there.
