What kind of oil are you using? When I was using Maxima 927 mine did the same thing. My pipe was running too cold and my jetting was too rich when this happened. It was also my first year with a Superjet so I wasn't very hard on the throttle.

im using pro axis racing oil and i have noticed too that my head pipe is cooler than usual
head pipe set up
bottom closed
middle closed
top 2 1/2 open (is this to much).

I think my head pipe is set to:

Bottom - 1/4 turn out
Middle - Closed
Top - 1/4 turn out

I think 2.5 turns out is too much... probably running the pipe too cool.

Right on bro!! I use that exact oil myself... it's great!


Tubbs... I had JSS change my plug wires on the waveblaster coil... they did a great job.

On my buddies 750 SX there was a bunch of gunk in the head pipe and coffman dry pipe and it turned out the o ring on the head blew and was letting water from the cooling jackets into the cylinder thus creating the sludge.
