    Clattery engine.

    Hi all.
    Been going through the Falco, top to bottom. Picked up a low mileage RSV engine and popped it in, (I wish it was that easy!)
    No doubt about it, my original engine is much more clattery than this one, although it performed excellently. Very good fuel consumption, usually a sign that things are worn if it gets thirsty, absolutely no smoke on accel OR decel, started on the button with a steady even tickover, usually a good sign that valves are OK.
    Now I have the time, I'll be taking a look inside my original engine. Anyone any pointers to look for? Its the kind of clatter that wold suggest a worn bush or bearing, might be nothing more serious than valve clearance too wide.
    So, basically, what areas should I concentrate on?

    Cheers

    The first thing id check is the cam chain tensioners, if theyre weak they will cause clattery sounding motor.

    Forgot to add that it has 35K miles on it. CCT's do sound a likely candidate, thanks for that, might be a very easy fix! Keep on with the pointers, might as well do the job properly. Had in inking to do the gen 2 head swap while I've got it out. Might be putting a shout out for a pair in a little while....

    Cheers.

    Last spring had a spanking new Z900 demo when my Falco was at the shop. At idle didn't even notice the kwak was running. My push bike makes more noise. That thing was so silent compared to my clunky and rattly Falco.
