  • klx cylinder head

    Guys my klx250 cylinder head has seen better days.
    the cover wasnt screwed down properly by the previous owner, and it now sports a rough surface.

    is there anyone in Perth that can machine these back to life?
    i've rang around and so far no one will touch it.

    replacements aren't easy to come by either.

    i'm sure im not the first person in this boat.
    could someone with a bit more know please lend some advice

    are u talking about the rocker cover??

    is the rough surface causing oil to seep out??

    if so just use gasket goo.

    otherwise i have no idea what your talking about mate
    Lost and on reserve

      you would be supprised what you can do with a file, especially on alluminium.

      just what cover is it exactly?

        There was a bloke in welshpool - down a bit from K-tec from memory, not sure if he is still around, cant remember the name though - maybe someone can refresh my memory?

        Also Ray Eassons Motorcycle Engineering in Bayswater do alot of bike related machining - give him a call on 9272 8466 and see if he can do it. I had my RMX barrel rebored there - charged a pretty compeditive price too!

          thanks for the advice OIF

          not the best picture,
          but as you can see, the sleeves under the cams are pretty darn worn now.
          it would have been nice if kawasaki made use of replaceable sleeves like any other engine i've seen. im not sure if this is the norm with bikes

              Hmmm hard to tell from the pic how bad it is, but i think yer only option is a new head if the wear is bad... Not heard of anyone repairing these, the cam caps are a machined match to the head as well. What year is the bike?

                It's a 2001.
                I left it with hamish engineering in welshpool and just waiting to hear back as to whether he can machine it at a reasonable price.
                Otherwise its off to the wreckers with my bike.

                I've tried to find a replacement head but can't locate one.
                The bikes only worth about 2k so I can't go nuts

                    sure that can be repaiered. all they need to do is skim the bottom of the caps to make the bore "squashed out of round" then re bore it. but apart from the first journal bore (before the valves) the cam rubs agains the caps so the bore on the head side dosant matter too much.

                    besides, if its only worth $2k, i would almost try it myself with a small brake hone and a drill extension. you would be suprised how long it could go for with just a simple cleanup.

                    just what surface is it that needs repairing? is it the bore? or the top surface where the caps mount?

                      Have a close look...

                      Not an easy machine job to redo the camshaft bores, no access from the side with the rocker cover on...

                          It can be done...

                          But you will find it's an "uneconomical repair"...

                            Bingo.
                            After leaving my parts with hamish for over 3 days and numerous voice messages, he was nice enough to finally perform some customer service and provide me with a quote.
                            ...Looks likes its off to the wreckers with my first bike
