Currently gonna try these in the pic on the right below. U can see i have modded and opened up the cage alot compared to the left ones i was running and removed the bridge for more open area. I have a kx65 cage coming which i will prolly use with 4 petals aiming down, and try my brothers vforce setup as well for a a full detailed comparison on all three. Reason i went with vm26 is that air filter mount is same as vm20 i was using, and with our custom airbox setups that are a absolute must it was simpler. As far as rpm, this bike only makes power at extremely high rpm anyway with porting and such, output is adjusted with clutch and variator and belts so it never uses low rpms anyway. It pulls super hard anyway, just trying maximize things. I am bored as fuck.
