| Re: K650 case porting
On mods like this, the stanadard we use is a back-to-back on-water test. I would love to tell you that case porting ($210) makes a "big" difference .... but that is not the case. It does help on very high-rpm biased K650 setups ... less so on lower rpm recreational / free-ride setups ... You be the judge of your needs. The effect on signal is very ... very small.

would this increase in crankcase volume threngthen or weaken the already weak intake signal?
have you guys ever done any crankcase porting on the 650? |
