A couple of quick questions...................
My ZX12 POWERPACK came with two rods, is the second rod the updated version or is it the same as the one in the engine?
If they are the same should I break-it-in with the one that came installed then change to the second one or can I just run-it for a gallon or two then switch?
What is the average life-span of the stock rods(I run them hard)?
Last but not least, is the Palmeris(sp?) rod a must have for this engine?
