Gates 21C4140

Just put on gates belt very impressed with to pull compared to factory belt. Polaris belt never pulled like this belt even when new. However belt temp seems to be running slightly higher with gates vs the OEM belt. During break in this morning it would run 15 to 20 degrees warmer than OEM belt. Was getting temps on alba gauge ranging from 145 to 155. OEM never ran above 135 or so driving it the way I was while breaking belt in. Anyone else experience temp changes. My guess it’s due to different belt compound.
