    Trying to replace Mikuni with Keihin PWK. The PWK came off a YZ250, has TPS and power jet. Hooked up carb, leaving electrical unhooked. Idled OK, fouled plug when I hit mid-range. Did it twice, same result. There's gotta be something else I missed. Didn't do anything to stop up power jet. Is that the problem?

    Did you remove the TPS plunger and other components? If so, that circuit will be in a constant open state and will always be delivering extra fuel.
    If you didn't remove then the plunger will be constantly closed and there's no problem.

    I learned all about this when I installed a TPS-equipped PWK36 on my CR.
