Hi Achim,

Not a direkt tip, but some other "entertainment" with @ crashbows ...

Last weekend I fixed the problem of (old) H&B crashbows (breaking
cooler screw) by fixing the upper bars directly to the frame. Works 
relly good with M8 screws, a bended 25x4 steel bar and a clamp around the
frame. Including the bar between left and right bow IMHO my crashbow is
the most stable now available :-)))))
And not just an optical accessory, like I classify most commercial
crashbars on the market.

But, as mechanics say, always the weakest point in a construction breaks
and so I realized 2 days leater that the holder of the engine protector
had been fallen off (due to vibrations I think, reported by others
 earlier) :-(

This connection is really a joke !!! I welded it to the frame again and
hope that I have choosen a better method ...

So my advice for you, Achim, would be:  If the part is worn out don"t try
to fix it with helicoil or whatever (wouldn"t be possible anyway, I
think ???). Just cut it off and think about a new and stable construction
that really holds the engine protector as a protector and not just for
being there !
