I've research and found that you can do the paper towel test on the headers but that's not accurate. Can I describe my symptoms and get advice as to what the problem could be... I really don't want to fork out the money to replace all 4 coils if this is not the cause...
I have 2006 FZ1N with 25000kms on it... Plugs were apparently replaced when I bout it at 22000kms... Problem seems to be getting worse... My mods are FCE, unkinkable fuel line, gutted cat, slip on, bmc air filter, lars airbox mod and blocked ais... I get no exhaust popping on decel. I only get it on acceleration when it's above 4500rpm... On part throttle and if I maintain a certain speed, I generally get this misfire or slight hesitation at around 3500rpm to 6000rpm.. Above that it's fine or if I give it a fist full then it accelerates fine... Sometimes I do get a slight bog feeling if I hammer it from 0 to 100 throttle... but that's not a big deal...
The biggest problem is when I rev the bike above 4500. If I hammer it to say 8000rpm and then either change gears or close the throttle and then reapply it slowly, I get this huge hesitation or feels like I'm hitting the wall and the bike feels like it's going to bog right down and then it goes again.. I get a lot of exhaust popping on acceleration if I hammer it and then reapply the throttle smoothly... If I change gears and apply the throttle rapidly then I don't get much of the popping or the bogging feeling...
It idles fine, well it does hunt a bit but only between 1200 to 1300 rpm so i think that's normal... I've checked the error codes and I only get 19 and 22. I've cleared it and get no codes for a while and then 19 reappears followed by 20. Then clear it again and only get 19.
My only guess is that I need to replace the coils. It's not the FCE as the problem occurred even without the FCE. It's seems like it's getting worse... I've done some research and I think I have 2 issues here. the hesitation/ misfire and part throttle I think is related to coils (someone please correct me if I'm wrong) and the popping on acceleration is the ecu fuel cut issue on the 06. Even though I have the FCE (this is the 2nd unit) and I do feel the abrupt throttle issue reduced, I still believe the popping and bogging on reapplying the throttle is related to the fuel cut. I think I'll need to take the plunge and buy the 2012 ecu unless someone can suggest what else could be causing this problem
