Mopar, I agree with you 100%. I am basically sticking with my plan to send the carb to Bigs and get the stage III upgrade for initial tune and performance. After talking with Jesse from Bigs on the phone, I feel confident that my 650 will come back to me and perform better than I could ever tune it. They are doing more than swapping some jets or power valves. Jesse even told me that I should take it to a dyno and may have to swap jets in the future. But he did say that when my carb came back, there would be NO sluggishness, no hesitation, no missing, perfect off idle response and so on. I have high hopes since this is going to end up costing as much as buying a new 650 dp. Check out Bigs site
