    Recently I got my mc22 put on the dyno to see how much power it was making and the results were shocking to me. It made 27.5 at the wheel and the afr was horrible.
    The bloke told me to go one size down in the main jets and two sizes up in the pilot jets and it would make a massive improvement. My question is how big is that improvement going to be 3b8a254d3036aad28a0847bffeddcfab.jpg a1541c9c609a32d646e5f8fbf206e696.jpg

    First thing I would check is compression and valve clearances, if/when that is all good move on to the next issue.
