The bike in question is a 91 Ninja 750. It's got a jet kit, pipe, andAccel supercoil kit.We installed the new coil kit Last night. Put a charge on the battery and she fired right up. Made a couple of test passes up and down the street. Then my buddy took it for a run around the block. It didn't sound right as he came around the corner. Let off the throttle and would die. Took the plugs out, they were old. Put new plugs in today and double checked the gap. .035 is what they need. Ran good for like 5 sec. and the same thing.

 

jets= more fuel
pipe=more air going out
now she needs to breath more air in. did you change the airfilter to a more free flowing one??

 

Not yet. But It's a major power difference. Buddy just called me and said that he switched 3 & 4. It will idle now but no power. Picking it up in a bit. Will get some pics of the set up and will try a short vid later tonight though. They think that it's getting too much fuel.
