Vent hose to airbox or not?
Hi,
when I bought the bike the engine crankcase vent hose was open to vent to the atmosphere, below the engine. On the airbox, at the bottom of the box, there is a hole, which can accept this hose - appropriate diameters.... I was wondering if this hose should be routed to the air filter box or left to vent to atmosphere? Any impact on engine life, operation, performance, consumption, or...? |

either to the airbox or put a pcv valve on it so it doesnt suck dirt into engine.

IMHO the best way would be to run a hose as Pete suggests with a small breather filter on the end. You could combine this with the PCV valve/one way check valve idea timcosby mentioned.
That said, the airbox combined with the PCV valve will also work fine. There are other options as well. It really just depends on how ambitious you are feeling.

I ordered a Microgard PCV112 from O'Reillys (You probably don't have this autopart store in Serbia?) and routed it to up and behing the airbox over the chain
