I have an 04 650 v2. I just snorkeled it with 2" PVC. My question is, what size are the stock pilot/main jets, and what size should I try. I know all are different and location will make it different. Just get me close. I live in east central Mississippi. Stock exhaust and Dynatech CDI box.

Did you buy a jet kit or are you just gonna go get jets at a Harley dealership? I'm not sure what your factory jet sizes are but if you check out the "pinned" section on here there is tons of jetting info. You would start with a couple sizes up at first and go from there. If you don't have a Wideband sensor, which makes tuning so much easier, then you'll have to buy a few spark plugs and do some plug chops. This is when you drive about 10 mph and do a full throttle run to about 40-45 then when you reach that speed you cut the engine off right away. Pull the spark plug and inspect for color. It will explain more in the pinned section.
