      ^^ then you are gonna have unburnt gases left in the bike at high revs, killing the performance of the machine.

          I've re-attached the pic , hope it makes sense now.
          on the similar note .. can head porting be done using lath-machine ?

          i thought they might contribute to the torque at those RPM but yeah unburnt gases left might give knocking.

          so any body tried welding to give high lift to the cams????

            I am running on Xtreme cam in my unicorn & to be frank the vibes have been reduced a lot & knocking reduced to atleast 50% so that the engine pulls effortlessly with pillion too.
            Lower side is mileage
