Well, just spotted the new 21 CMB. New intake and a balanced crank.
Let's see if production can satisfy the demand.
Looks nice anyway.

It has been tested in Germany and stock it was about 1km/h slower then a modified "old" intake system.

Why do we not use the Zimmerman disc system in the 3,5cc engines?

Been there done that and maybe it's time to take up the tests again.


Zimmerman is a flat disc instead of a drum on the intake.

Can anyone tell me about the pros and cons between the drum intake and the disc intake?
