This may all sound strange but just installed - PPK, 13/19 prop, intake grate and Rideplate. Totally amazing difference! Decreased cavatation, holeshot great, but now it seems I have a small bogg or miss when I open it up. Seems like 0-5mph there is that bogg. I'm not sure if the if it is loading up at idle? My plugs are a little black and wet..NGK -11's. What gives? I have check compression all is good there, no adjustments to carbs yet, do I need to now after mods?? Change plugs or tweak low-end on carbs. All jetting is from factory, whatever that may be, just got ski so did not have a chance to scope out all settings on ski. On another topic, with my current setup, PPK, intake grate, ride plate, 13/19.. What would be the next mod(s) on the ski, without losing reliablity.. Should the head come first? D-Plate? Just looking for a little more kick! But really don't want to be making adjustments every other day... atleast not yet.. Also, what's the difference on the dreamo-speedo? Say's 77mph?? yea right!! Thanks for the Feedback!

D-Plate is a must have just so your cat con does not fall apart and clog your exhaust. I have been told that heads increase low end torque not top speed but then again I have a XLL.
