jdels 138 Posted January 4, 2022 Share Posted January 4, 2022 (edited) First two rides on a new to me 2018 ZR8000. 137'' studded down the middle, 2200 miles. About 15 degree weather both today and yesterday. Maybe three inches of hardpack on most of the trails. Struggled yesterday keeping temps below 150. When I got home I raised the front end about two feet up, warmed up well and added about two cups coolant, thinking air pocket. Went out again today and same thing. Unless I dipped into powder frequently, and I mean nearly constant, temps would rise to 160+. A blast into some powder and temps would drop 25+ which suggests the heat exchangers are functioning well, just no snow getting to them. Are scratchers a must on these machines? Any other insight would be helpful. For reference sake my two kids on Sabercat 500's had no issues, nor did anyone else in my group. Thanks.
