Hi there

I recently learnt that one can install a Crankcase Pressure Release Valve that will help to reduce the pressure in the crankcase resulting in a small power gain and better fuel economy.



The parts needed can be found here:

Anyone tried something like this on a GSXR 400?

It looks very trick but the bike already has a breather on the head so you will not get problems with pressure.
