    Dear Frits,

    Am I right that at the original Malossi MHR team the boost ports are to small for 20 hp?... in window size and in inner port diameter ?
    Mainly the diameters seem to be verry narrow for my understanding ?

    Thanks !

    Grüße Wolfgang

    Wolfgang, I assume that with 'boost ports' you mean the auxiliary exhaust ports? As you may have noticed, that Malossi pipe design was dated 2004. That's 22 years ago. You may well be right in your assumption but I really cannot remember the details of that MHR cylinder anymore.

    You are right to ask the question Frits, for some reason many Europeans call the Aux Ports " Boosters", or Boost Ports.
    This conflicts with what everyone else knows as the C port or Boost Port.
    Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

    Good morning Wobbly and Frits from Germany

    Thanks for finding right words ...while i wrote couldent find to express what i wanted to tell

    We call the C Port " Stuetzkanal" and the Boost Auxiliary "Nebenauslass"...

    By the way if i remember right the horizontal inner width of Auxiliarys in the Malossi is only about 4mm...next to nothing...

    Viele Grüße !

    Wolfgang

    There is a historical precedent for using an old German naming convention of anton bruno caesar.
    Dora could be the Exhaust due to the shape

    Please don’t remind me of German naming conventions.
    In principle, writing German is simple enough: just make every word three times as long and end every sentence with three exclamation marks.
    When asked by my German friends, my polite opinion is:
    “German is a much richer language than, for example, English. German offers far more opportunities to make mistakes"
    (war nicht persönlich gemeint, Wolfgang)

    Ah well, English is pretty daft also. I've read that the Belgiums owned a lot of the early printing presses and helped with the spelling.
    Don't you look at my accountant.
    He's the only one I've got.

    No problem Frits and the others involved

    You managed it to put a magic grin on my face

    German lessons were really hard time
    Getting older and only learning what interests you is wonderful ...top

    Crankshaft work

    Another old picture found.
    In the year of 1998, I spent several weeks of my summer vacation to fullfill an even older dream,
    of designing and manufacturing a crankshaft for a KX125 motocross bike.

    The design work for drawings was performed on an "old school" drawing board and all machining
    was done in manually operated machines.
    Therefore I started the fine machining of the crankshaft with manufacturing of the crank pin holes,
    then assembled the crank with an undersized pin to obtain only a light press fit,
    and turned both shaft ends and main bearing seats in the same operation.

    The material is case-hardened steel 16NiCrS4 tempered to 58 HRC, and fine machined in the lathe
    after heat treatment process.
    The grinding was done by hand work - with diamond foil, a piece of glass and a lot of patience.

    Weight reduction holes are covered with thin aluminum sheet plates,
    and threaded wolfram inserts are positioned radially (not seen in the picture) in order to make
    adjustments of balance factor by just lifting off the cylinder.
    The conrod, needle bearing and axial shims are OEM parts.
