    [2001 XLT 1200] Any reason to inspect the pistons, rings, cylinders and heads?

    2001 XLT 1200, sat for 2+ years. Work in progress. Exhaust, stinger, and carbs are off. Rebuilding carbs this week.

    Is there any reason to inspect the pistons, rings, cylinders and heads?

    The last compression test was (#1) 121, (#2) 120, (#3) 110 (http://www.greenhulk.net/forums/showthread.php?t=127964).

    I have not cranked it since then. Should I expect any probs from it sitting for 2 years? I fogged it before storing.

    I didn't want to crack the heads and cylinders open if I didn't need to. Would #3 @ 110 psi be a concern? VRO is still intact. #3 oil line had not fallen off.

    I am going to do another compression test soon. I'm looking to give this a reasonable inspection before using it. Any advice on inspecting the engine would be great. Thanks again for all of your work and information.

    If it has a lot of hrs. on it and since you got it down that far it wouldn't hurt to install new rings and pull the PV caps and clean them wile the cylinders are off and put wave eater clips on the PV's. And since you got the pipe off install a D plate if it doesn't already have one. when you install the carbs. cut the ends off the old oil lines before you re-install them.

    130 Hours.

    PV holes look like:


    Going to get PV clips.

    D-Plate and chip installed.

    Installing oil block off, etc.

    Going to pull heads and look at rings, etc.

    ----------------------


    I tried to compression test it. Would not crank. Removed pump coupler cover and turned shaft by hand. Shaft is free.

    I used a 50-amp charger/starter in place of a battery.

    I get a noise from the CDI and my fuel sensor alarm is on (tank is empty).

    CDI Noise recording here: http://soundcloud.com/dsect/grrrrntb...ep-beeep-beeep

    Will these crank with the fuel alarm on? Will they crank if the water temp alarm is on?

    Is this possibly b/c I am using a 50-amp charger/starter?

    Thanks!

    get a battery don't burn out your starter or fry your starter relay.
    Yes it will crank with low fuel warning on.
    no it will not fire or crank with the rear lower temp sensor disconnected or bad.
    don't use that starter box.

    You might try putting a little oil down in the cylinders and let it sit for a few hrs and then retest the compression,the oil might help get the rings to seal a little better,especially since it sat for soo long

    I have a battery but it needed charging. I will use that from now on.

    I pulled the head, but it got late and I didn't get the cylinders out. Cylinder walls and piston tops looked real good.

    I will check the ring end gap to see if it's in spec. I will check other specs as called out in the service manual.

    Bottom line was, with everything being torn down why not check this stuff out? I wanted to avoid the gasket expense and the chance of introducing an air leak, but it's worth it to gain experience on this engine and to ensure things are good.

    If your going through the trouble to pull and measure the rings then you might as well just replace them if the pistons look good,ain't no sense in putting old rings back in,especially since they are a wear item and who knows how much longer they will last
