    Yes, please do. That looks almost too cheap to be good but who knows. Since I haven't pulled mine apart to see what they look like I am a bit surprised at how much they look the same as the ones on my Hawk. I will have to check and see it they are the same.

    I'll post an update when it arrives. Can't do any comparisons with the stock ones, as I don't have spares lying around, but seeing how cheap it was, I thought I'd just take a chance and order one.

    I took a quick look at my diaphragms today. Those might work on a 93 but there is no way they will work on a 94-97. I guess I better hope these do outlive me. @squirrelman#1

    The design on my 97 puts the vent pretty far from the piston so it has a very long part of the diaphragm that sticks way out. I don't think there will ever be a generic replacement for this part although you might be able to adapt something and fill in with some gasket maker. I just hope it never comes to that.

    Yeah... sorry for slightly mixing things up, as mine is actually a 3rd gen and not a 4th as per the topic. I guess the carbs are somewhat different between generations.

    So the vent is a rather large loop on the edge of the diaphragm rubber on the 4th gen compared to the very small loop on the 3rd gen?

    yes, pretty large loop.

    And the slide is different. Almost a flat plate instead of round.

    Interesting. Inside the airbox, it is like small velocity stacks too.
