    What does the top and bottom look like?

    So far that looks like a lubrication failure. Did one of the oil hoses disconnect or get kinked?

    Not that i can see. After i installed the new flywheel and stator i unhooked the oil lines and used a slotted paddle bit and drill and primmed the oil pump till it came out.

    On the engine the oil injection nipples have check valves inside. Make sure they are not clogged or stuck. Spray some solvent through if necessary. In normal operation the check valves take a modest pressure to open.

    Also check the connecting rod. There should be zero play up and down, and very, very little side to side at the crank shaft. The same oil feed that lubricates the cylinder walls also lubricates the crank shaft bearings.

    Ok thanks man. I will check that out. So u think it was a lubrication problem instead of an injector. If i ever had to replaced an injector where would i have it programmed or does anyone sell a scanner?

    Why would you think this is a fuel problem?

    The Ficht fuel injector is completely different from an automotive fuel injector. Does not work the same way, at all.

    There are some things that can be done to service a Ficht fuel injector, but I don't think that is where the problem lies.

    The top of the piston looks undamaged, while the sides have obvious scoring and metal scuffing.

    I would get a WSM piston. The Wiseco could cause you a whole new set of problems. THe WSM will be cheaper as well.
