    BR, take it with a grain of salt, but I'm wish FS5 on this. I think you need to go with a smaller main jet. You ought to get a set of each size down to .056 and set what happens.

    the tohatsu and yamaha are 1.85. the zuki is 2.09. Where a hatsu or yami would be turning a 12p, that is about equal to a 14p on a zuki. you should at least be turning a 14p in the 6-6200 range.

    Exhaust Question

    What is the best way to modify the exhaust on a Suzuki DT25C? I've heard of drilling holes in it. Anything else? Is there really a performance gain or are you just moving the powerband.
