Ok , so far what I did myself:
- sparks check, 12.6 volts on a line
-injectors cleaned, didn't connect them back yet, they weren't spraying when I removed them, 12.6v on lines
-upom removing airbox found out braket for the motor which opens throttle is broken, fixed with a superglue until new part arrives, and attached it back where it belongs
-ground checked found 2 spots on the left and right side of the engine, correct me please if there are more
- sprayed starter fluid into the throttle bodies, bike coughed few times but didn't fire up
- MAP sensors voltage checked 5v, although when checking for cyl#4 bike was shutting down and restarting few times, any ideas what it might be???
After checking map sensors lines voltage bike stopped cranking, it doesn't respond to start button.
Any ideas why? Any recommendations what should I check next?
