I installed a PWK36 Quad Vent this weekend, on my 93' KDX200, and it worked as expected by moving the powerband up a tad. I used my stock needle from the PWK35 (1172N?) set in the middle clip, and used a 155mj/42pj. I'm brand new to carb tuning, and I bought the bike non-running, so I don't really have a comparison. I've read quite a few jetting guides, and feel relatively comfortable with that... but how do I know which needle to use. Right now I only have the stock needle, and the one that came with the 36mm. Id ideally like to run the 36mm needle so that I can sell the KDX carb intact, but for the time being it made sense to use a slightly richer jetting along with the stock kdx needle. Below are a couple videos to listen, and see the bike (notice: I look like a goofy squid).
