21 street bob running rough

    Hey guys after some advice,

    I have a 21 bob with a CR 483 cam. When ridden it’s below 2200 rpm, it runs fine. Over 2800 rpm it runs fine, but in between 2200 -2800 it sounds like it’s dropping a cylinder. 
    Have replaced pistons and barrels but still having same problem. 
    Anyone had any similar issues?

    where did you get the work done and what tuner did you use?

    What tuner and exhaust did you have? The 2021 bikes are trickier to tune and that cam makes them real tricky to get right under 2850rpm particularly if you have a 2 into 1 pipe.
