Ok so I need some help as to what is going on with my 05 YZ250F. So I just bought the bike and it’s pretty much new! Has less than 15 hrs of riding on it! Bad news. The previous owner left the fuel in it and sat for 3-4 years or more. I cleaned the carb twice. Seemed to be getting better after both but then said enough and bought new jets. So the deal is. The jets I ordered are from al”all balls” I do believe. Well the sent bigger jets. Sry. I never wrote them down but anyways I’m new to the bikes and I’m pretty sure it just needs tweaked. Where to start? Sry so long!
