anyone with an idle surging problem or know how to fix it?
i've had my carbs fully cleaned and synced, valves as well, oil and filter change, coolant change, spark plugs changed and it still hasn't solved this problem. in the end the mechanic told me it was a common problem with ZX7's. it only does it when the engine is hot. the idle surges lower than the set rpm. it used to die as well but since the spark plug cap thingys (something in the plug caps called capacitors or something like that) were changed, it hasn't died but still surges. bike runs great when it's not hot, but once i get stuck in traffic the problem arises again. i can't think of what it could be and why it would only happen when hot.
