    Hi everyone!
    I own a ZGULK guzzi, a Nevada Club from 2002. I picked it apart before this season because there was sometimes a backfire in the right cylinder when I started the bike up and me, loving my ride, want no such thing.
    To my shock - after some obligatory cleaning - I noticed a small crack between the intake and the exhaust valves. Checking the valves, it is obvious that this crack is the reason of my occasional backfiring since both valves were blown clean of gunk where the crack is. The damage itself does not run deep, I initially though it was just some burnt carbon.
    So, what are my exact options? I am no expert in machining, so I wonder if the head be salvaged or I need to get a replacement head?
    Thanks for all the answers!
    Best,
    Balazs

    If you have a good machinist shop where they recondition cylinder heads, sometimes the cast aluminum can be welded. Most shops will tell you to just replace it. Often you can find cylinder heads on eBay fairly cheap. You can also easily use V7 heads from 2009-2012 also.

    Hi GT-Rx,
    Okay, thank you! I will take it to the Ducatti shop next week. Will see what they will have to say.
