    Rebuilding 260 hp motor

    I am in the process of putting back together the motor out of my RXT IS 260 and when I put timing chain in the lines on the gear cover didn't align with the head edge with both cam and crank lock in place so to align it I removed the crank lock and rotated it slightly to get the lines to align - is that the correct way? Moving the cam gear one tooth either direction did not work.

    Make sure you have the crankshaft locking tool installed into the correct hole! Others have learned this the hard way.

    The lines on the timing gear are normally slightly tilted to the left and NOT level with the head.

    Curious here. Will the crank lock it into TDC position?

    Yes I bring cylinder 1 to TDC and the locking tool slides right in as it should and the crank won't move anymore.
    How can you use the wrong hole - only two there are the timing tensioner and crank tool unless I am not seeing something.

    There's only one hole in the crank that wil line up with the crank locking tool. And yes, the cam sprocket marks wil be slightly tilted to one side or another. Either will work fine. Just make sure you have both the cam and the crank locked.

    It's # 3 cyl, the closest to the front of the craft.
    To double check yourself, remove spark plug insert long screwdriver in that cyl. and make certain it's at TDC.
    The locking tool should have made sure of that but you could have missed the hole completely.

    Most on here retard timing and find better performance from it.

    Ah my bad I thought that was #1 so yes that was the one I had TDC. So should I set it back to be slightly off or leave it

    When in doubt do it again. You don't want it close but exact.
