    "i said what the ****" think this hurt my performance? PIC

    also noticed alot of oil on what id call the intake manifold between carbs and reeds. so im changing oil lines and carb base gaskets.

    pieces of flame arrestor lid in reed cages.

    history:
    last august flame arrestor came loose and off and i melted my mag cylinder.

    dropped it off at a polaris shop and said a carb failed and leaned out the cylinder

    they rebuilt carbs and replaced mag

    i then scrubbed the mag on its first outing.

    they repaired for free

    got a half tank through it before it got winterized (in choppy water no sustained full throttle)

    took out of storage to find fuel dripping from pto carb

    they repaired free

    ran fine but was only getting to 6400 rpm this season

    rebuild the jet pump and added some goodies. original looked mint for age

    proccess of checking changing reeds and found this!

    plus lot of straight 2 stroke oil on manifold between carb and reeds so im changing lines to elimanate fatiqued hose and clamps



    do you think these pieces could have cost me some rpm?

    picture got mirrored on my phone. mag reed is clean,center is 2 pieces, and pto is one

    6400 RPM is about right for a 1050 I think. The 1200s get into the 6600 range.

    just feels slower on the top end. do you think the interfered with flow or am i living in a 4stroke head and valve world?

    May have caused a little restriction, or may not have allowed a reed valve to close properly. Either way its good to get that crap out of there.

    Have you done a leak down test on that motor to make sure the source of the piston damage wasn't a leak in the front crank seal or the mag housing where it attaches to the crankcase?

    They look like the reinforcing ribs from the underside of the flame arrestor.
