on my 860 on the last day of our two day ride(first day ran fine) bottom and mid run strong but as soon as i go to climb a i get like 15 seconds of full throttle it starts to sputter and if i hold it it will die out.... i was told to check the spring in the cluches and they were good, could it be the dpm?, or the rave valves?maybe water in the fuel not where the fuel filter is but will be checking that? any ideas
