Hi @ folks,

just a few statements to the "shooting discussion" ... :-))

A possible way to check to correct fuel mixture is the following: drive to a 
car dealer next to you and ask him to measure the exhaust gases. What he 
does is the following:

He puts a "sensor" into your exhaust (looks like a hose).
Then the values of your gases (your bike's,not yours...) are displayed on a 
monitor nearby.
By opening the throttle, you can check them also at higher rpm's.

A friend of mine told me the following: it is much more better to be on the 
rich side because you lucrate a bit more power with that - on the other 
hand, the fuel consumption raises...

You can test this the following way: dismount the airbox and close ONE pane 
of the original air intake with some pieces of old clothes. (If you find a 
better way to do this, feel free to try it ... :-)) ). Now your engine 
definitely gets too less air - so it has to be to rich. Therefore, your @ 
should have some extra horses now!

I have to state, that I didn't try out what I described above - because of 
the following:
I drilled up my airbox on the left and right side (take a look at Raymonds 
HP), and I totally closed the original air intake - because my @ got air 
from the extra holes.

The only thing you risc by trying this is to use some extra liters of petrol... 


greetings,

Achim Muehlberger
