Hi. I run a KTM 1190R V twin drag bike and have binned the early type Keihin ECU. I am currently wiring in a ECU Black, however the bikes stock trigger is an issue. The motor design is a 75 degree V twin, Looking from the left side of the engine it runs CCW, with the rear cylinder as Number 1 as standard and a 435 degree rotation before before TDC on number 2. The only trigger is a 24 - 2 rotor with a two wire VR sensor pickup. Fitting cam sensors to both banks is relatively easy, but how do I trigger cylinder two with only one crank trigger and no wasted spark option available? Are separate cam triggers an alternative option to a crank trigger?
