I own a DRZ400S and tried using the JD jetting kit with my airbox mod and stock exhaust. So I put the new 25 pilot and 150 main jets in and my bottom and top ends are fantastic with the stock exhaust and the 3x3 airbox mod. I swapped the dynojet needle for a JD blue needle, on the suggested clip #2. But it simply cuts off fuel and won't rev up at 1/2-ish throttle. So I put the dynojet needle back in on clip #4 as per Dynojet's manual and it runs better, but it feels very lean in the mid range (gets very noisy and very uncomfortable when revving, I think it's lean because the engine sounds like it's hitting the limiter at 1/2 throttle and I absolutely hate the noise.) I'm at 50ft above sea level, anybody have any ideas? I want to try the JD needles but don't want to take the carb out a million times tuning it, so I was thinking I'd put the Dynojet needle on clip #5 to try and richen up my mid range. But then again maybe I'm completely wrong.
