Acquired a gently used Pioneer 1000 recently. My first side by side. I noticed that when getting up to speed it was cutting out and would not get over 15 mph. I went ahead and changed oil, oil filter, air filter (that was a pain to get to) and the plugs as I had no idea when those were changed last. It still will not get up to speed so I'm thinking fuel pump is next. Anyone have experience with this model? It suits my needs perfectly, climbs the steep trail with no problem, dump bed will be useful as well.
