Engine missing at revs

[NVS 90]

hey all. just wondering if anyone could help me.

i have a VN series 1. when i get up it it starts to break down. it gets to about 3000rpm and doesnt rev smoothly.

ill be checking the crank angle sensor today, but i have replaced the coil pack and the DFI module looks good.

any idea why it breaks down.

thanks all

I second that - under load like going up hills - first place to look is leads

Hey man

I had the same problem after I changed my CAS, what it was is the CAS is adjustable and that can alter the timing. I adjusted the little white unit on the CAS one click and it made my car run mint

An hairline crack in a spark plug can also cause the symptom you describe.
