tuning help

if you pull your plugs from your ski right after letting it idle in the driveway are they supposed to be wet or dry? also, when im riding and i jump out of the water i take my finger off the throttle, but the motor seems to still be reved up until i land again. what does that indicate? and as i try to tune my low speed screw with the ski on the trailer backed in the water everything works perfect like group k syas it should. i turn in the low speed screw until it cuts out and that whole thing. but then when i ride it doesnt hit hard at all, it boggs. at that point the screw is at 3/4 turns out. when i go to 2.75 turns out it acts alot better but not perfect

ohh yea that would help. i dont have a tach. its a 61x superjet bored to 733cc with a riva red pipe, 180-185 psi, msd, 46mm mikuni carb with 127.5 low speed jet and 155 main jet. the main jet is most likely rich right now until i get the low speed tuned right.

Well the first thing I would do then is get a tach so you can properly tune the motor. A tach. is cheap compared to a new cylinder and pistons.

i dont have a pop off gauge so i cant test that, i will try to find one tho. ill have to take the carb off to check out the needle and seat i dont remember. i think maybe 2.3

maybe ill just change my needle and seat since i have extras and see what it does. or just change the spring. what do you think? weaker or harder spring?
