Super hot at Black River Falls (Wi) trails and the Prowler fuel vapor locked terribly on hot soaks after hard runs. I'm not sure if was the heat or the fuel, I was running 91 octane pure fuel, no ethanol. After the engine would finally fire up and stop sputtering after cool fuel found its way to the carb, it ran great. I think I'll wrap the fuel lines this week, but won't find out if that's the fix until the next hard run. But, it won't be at BRF, those trails are meant for RZR's and Wildcats. The Prowler took a lot of punishment, but our bodies took more. The suspension is not made for these kind of trails.
