I just bought a 2012 650 max xt with a whole 23 miles on it. I brought it home Monday and it ran great, put about 5 miles on it and was very impressed with it. I went to take it out tonight and it is only running about half power, low rpms when wide open and can only max out about 20 mph. It doesn’t idle great, likes to stall but will start right back up. I siphoned all the old gas out and put new gas in, no change. I do t really have much time to work on it and will probably take it in for service, but looking for thoughts. Thinking fuel pump or filter? It’s lived in a climate control garage it’s whole life and has never left the prior owners yard. It looks like it just came out of the crate.
