    This is probably just a very easy fix but was just wondering what it actually is, I haven't got much time to be messing about these days so knowing what I'm doing would be helpful.

    Thanks for any feedback :p

    As I recall, the CG is a push rod engine, so no problems with cam timing or any of that melarky.
    Fuel off
    Tank off
    Loosen the carb' rubber and slide the carb ou.
    Exhaust off (use coppius amounts of plus gas and gently on the retaining flange bolts).
    Unbolt the head and remove.
    Clean and gasket faces on the head and barrel.
    New gasket.
    New exhaust gasket.
    Re-assemble as above in reverse using correct torque settings.
    Run gently for a tank of fuel and then re-torque.
    Check valve clearances.
    Done

    Are the valve clearances easy?

    Fiddly and requiring patience, but not difficult.

    Which bike?

    Ktm.

    Lol.

    Tbh id rather do the cbr.
    Its a right pain on the ktm to do the plugs.
    Access is so tight due to the frame design. You need a very skinny 3/8 drive plug socket and an array of extensions or you cant get in the top of the heads.
    And the tank is notoriously difficult to get back on due to the plastic growing slightly over the years.

    Great on the Guzzi. Loads of space unlike many.
    No crouching as the pots on a Guzzi are proudly pert like a young girls breast, unlike BMW's sloppy saggy spaniels ears.
    V-Twins are great, but when orientated correctly in the frame, they're brilliant!
