Single cylinder bike engine
I'm helping a guy that is building a cross kart engine, it's a Honda 650 cc 4-stroke (about 80 hp). It has no suitable trigger wheel for exact timing and cam sync. We are adding a 12-1 trigger with VR sensor which is custom-made and adapted from a KTM bike engine with the same sensor and we copied the wheel design (teeth length, depth, width) other than the KTM one uses 18-1. The gaps are about five times longer than the teeth.
This type of trigger is not of zero crossing type, more of level crossing type, which might mean we need special adaption on the trigger input. The sensor is 230 Ohms and below follows scope shots of the trigger. The missing tooth does not overshoot much, what do you think?
