can anyone walk me through doing this? cant make sense of the owners manual and dont have a clymer or haynes.. any help would be appreciated.trying to eliminate gas smell from exhaust, it smells very heavy and even the back side of the airbox smells like it

 

i pulled the connectors off each coil individually. every time i unplugged one the bike started running like crap, until i got to #4 (the coil closest to CCT) when i unplugged it, there was no change.. when i plugged it in, it would surge up in RPMs for a split second and go back to what it was at...then unplug it again, same thing, no running worse or anything.. safe to say i have a bad coil? how can i test the coil and wires to make sure im replacing the correct thing

 

Switch that coil with another cylinder and retest. If the problem moves with it your coil is bad. If it stays, keep looking.

 

it stayed, it did not follow the coil. any ideas? bad cylinder? low compression?

 

Any of those are possible.

Next is to put a plug in the coil and ground the plug to see if it sparks. That will confirm signal to the coil. After that, check injector and signal, plug (you can swap those around too), compression, and valve clearance.

The coils and injectors have a common power. the ECU grounds each to make them work. Being that you have an excess of fuel, it's probably does not have a bad injector.

Have you checked the FPR yet?

 

when you say plug the spark plug in the coil and turn the bike over while it sits maybe on the head or block or something and see if the plug is sparking off the head? how do i check injector and signal?

 

and yes fpr was replaced 2 years ago but i have a brand new one that came in today actually. im basically throwing parts at it and i cannot afford to do that lol i appreciate your help

 

Yes, ground the plug with it in the coil and wire hooked up. You will see if it sparks when you crank it.

Got spark.... Coil signal is good.

Each injector will have constant power and a pulse ground to make it work. A test light on the signal side while cranking will show the pulses, unless you have a noid light instead to test it. You have tons of fuel, so I bet everything will be fine there.

Do you have a compression gauge?

 

I don't have a compression gage but I'm going to go get one this weekend and do a test. What is the correct area it should be in? Also if compression tests fine what's next? What do I look at next?

 

Just did compression test and not sure if I'm doing it right. I got
1=50
2=52
3=60
4=52
I am following the directions to a T. I have the fuel pump plug unhooked, all coils and spark plugs. I'm using a harbor freight compression tester I just bought. Part number 69885. I am screwing it into the hole the spark plug goes and getting it as tight as I can by twisting the hose and all and then attach the gage and open the throttle all the way and hold the start button until the gage stops rising.. Any ideas or is it just that bad? Doesn't seem to run bad enough for all 4 cylinders to be THAT low on compression?
