    Im having trouble reading these, but il take a shot at them, in the first cylinder you appear to be running lean, in the second pic the cylinder looks like it needs to be richend up just a little.

    thirsty = more fuel right ?

    Its a 1200r
    135 lb compression
    VF2 reeds
    110 pilot 120 main 95g dull spring lows are 7/8 out and the highs are 1 1/8 out
    05 pump w 14/20
    It will turn 7210 on a cool morning and 7150 - 7160 all day

    The 14/20 is a big prop for a 1200. You definately are running hot. Try going up a half jet on the mains.

    I'd think a boost in compression along with the jetting change would be a great help (and quicker) with your pistonwash.

    My opinion is 120s are to low. I know some get away with it but I feel its to lean. 125s are what I suggest and what I run on the 1200. Wash looks great and it is faster.

    When doing plug chops I run it for 15-20 sec @ wot then turn it off...Is when the piston wash developed relevant ?

    For example - before I turned this off I had a long run @ 5500 - 5800 rpm's (15+miles). Then I had to run it for 10-15 minutes on a broken reed.
