Im trying to get a Vapor computer to work on my 650L based road racer and was wondering how most people are wiring up the rev counter lead? I have tried both wrapping the lead round the HT lead and hardwiring the pickup on to the black/yellow supply to the coil from the CDI. Both give 'off the scale' readings no matter what pulse per rev number I use. I think I may have a duff CDI. I will put some shielding onto the pick-up lead before ordering a new CDI but am still interested in what you guys have got to work reliably.
