    Third replacement cylinder head shows early signs of wear

    After 57,500 miles and three cylinder heads, the latest replacement head (at 38,180 miles) is reportedly showing signs of valve wear at 57,500 miles.
     I Can't see any other reports, so must conclude that I am the only one.
    I guess I'll just have to run it into the ground with only minimal servicing, last spend 60,000 mile service c/w new rear brake master cylinder and apportioning valve due to brakes binding on on front right and rear Disc 1063 ouch!!

    Just curious - Exactly what type of "valve wear" ?? I have heard that some of the early engines such as your 2013 had valve guide wear and were replaced under warranty because of "soft" valve guide material.

    The dealer mechanic described carbon deposits on the valve stems, as I didn't see the disassembled engine, I can't add any more, though it was suggested that I use a fuel additive like STP to try to extend the life of the head.
    The is not the head supplied during the recall, that one failed a couple of years ago at about the same mileage, and Triumph supplied a new one as a goodwill gesture, and I paid for the installation, luckily? about the same time as I had to have the alternator replaced, so two birds with one stone there.

    The best additive for these cases is, from time to time, before changing gear, accelerate as much as possible without reaching the ignition cutoff.

    Our bikes have plenty of room to get to the point of the ignition cutoff.

    It is the best way to remove carbon from the combustion chamber and valves.
    Only motorcyclists know why dogs stick their head out the car window.

    Many thanks for the hint, where I live, on an island, we don't have much in the way of open road to achieve that kind of acceleration, but next week we'll be away in the mainland UK, so may get the chance.
