Got an 07 250 that I try to start and ride a mile or two at least every couple of weekends during colder weather, but recently when I started it to ride after thorough warm up, when I pulled choke off the bike stalled. It now only runs with full choke and even so tends to stall out when I come down to neutral from any gear it stalls out. My local shop says gummed carbs, but I just find that hard to believe since I try to fire it up and run it regularly. Plus I drained the bowls and the fuel looked completely normal. I'm guessing valve adjustment b/c I've yet to adjust valves and I've got 1,000 miles on it, but they are telling me I shouldn't have to do that for several thousand more miles. Is that true? I thought these were notorious for needing frequent valve adjusts. Anyway, just looking to get a feel here, I don't want to get taken for $200 on something I might not need. Any thoughts? I'm a fairly mechanically inclined girlie so I think I could do just about anything if I could nail down what exactly it is.
