ok my i cut the connecting plug off front wire harness so that i could wire up my street fighter head light, i know on f4i's when you cut headilght wires you have to bypass the tip over sensor, but be as my f4 isnt the same as an f4i in that matter, could this be why my bike wont start run or do anything, lights worked when i had it wired up, horn and brake lights still work but doesnt do anything when i try to fire it up, any help thanks

 

I think the F4 does have a tip sensor
also test forkickstand switch, ignition, start switch, fuses
