I have a 2002 WR426 - grey wire, lid off, bk, power now,uncorked, yz throttle stop, live in Palm Beach (low sea level)- 42 pj, 165 mj, drs 4 clip,pj 1 1/2 turns, the rest is stock.
The bike ran great for 3/4 year. Then it started sputtering - easiest to notice at 1/8 - 1/4 throttle. But seems to do it all the time. Traded carb with a friend and the problem moved to friends bike. So it must be in the carb. Carb cleaned twice by me and once by the pros. No joy. Traded my stock drr needle for a leaner drs needle 4 clip. No joy. Tried an ekp needle - worse. Tried a 38 pj - no joy. It seems to come and go. I took it to Yamaha & it ran ok. They said they didn't think it was worth working on. Brought it home and got it hot - sputtering out the exhauset. One other thing. When it starts sputtering it feels like I sat up and the wind caught me. Not a surge - an unsurge. Like a rubberband pulling me back. email me if you can help firstname.lastname@example.org

Did you change gas or air filter oil?

RB - I've changed a lot and it stays the same. I think it might be what sends the signal to the TPS.
