Hi Marcus,

I think power reduction is simply done by a reduction of the air 
inlet tubes between the carbs and the engine. Small metal plates 
inside are used to reduce the diameter. I think additional changes at 
the carb adjustment will be necessary to make it work efficiently.
I think there is a pasage about that in the german 
"werkstatthandbuch".

I don't know for sure if a change of the nozzles will be necessary, 
but I think turning aut the "gemischregulierschraube" will be enough.

The 58 hp tubes  don't have any mark ouitside, whereas the 50hp tubes 
are marked with "50 PS" and the Honda part number.

I had some problems in getting the real power (58PS) permitted by 
TUeV, because I had no bill from a Honda dealer about the changes, 
because I did it myself. Try to call different TUeV's or better Degra 
before. Normally it should be no problem to increase from 50 to 58 hp 
because you will have to pay more maney for insurance.


By the way:


Does anybody know how to adjust the carbs by using an external RPM 
meter (which is more exact)? If got one normally used for cars which is connected betwen 
ground and the 12V signal to the spool (Zuendspule). I tried to 
conect it to the input of the enternal RPM meter but I failed. What I 
would need is a 12 V pulse from the ignizian system. Is there 
something like that coming out of the CDI?

Is there anybody who tried this before?
