Hello everyone!
I'd like to thank anyone that helps out in advance. I've read through way posts, and cant seem to find anything beneficial. So, I recently purchased a 2006 FZ6 with about 20,000 miles on it. It also has a PC3, two brothers exhaust, and K&N filter. Ever since I bought it a few months ago it has had this super lopey hunting idle. The idle will jump around from 900-1,300. It was really cold the night I got it, so I assumed that the lope was from being cold and sitting. Either way, It started to creep up my skin and it also smelt rich. Like rich to point that after I ride it. My clothing will smell very STRONGLY like it's exhaust. I figured that it probably just needed some new plugs, replaced them, and no change. The old ones didn't really indicate wether it was running rich, but also didn't look old. So, i figured that maybe the previous owner changed them recently to possibly try to hide this issue. So, then I tackled the throttle bodies. I used a manometer and also tried using 4 separate vacuum gages. Still, its horrible if not worse now at factory spec. Plus, it was almost impossible to set the idle before adjusting the throttle bodies cause of it jumping around so much. Whenever it seemed like I got it smoothed out. If I turned the bike off for a few minutes and started it back up, its back to the lope and not acting like it did prior to shutting it down. Another symptom arose while I was doing the throttle body sync with having the bike sitting and idling (with a big shop fan blowing on it) for probably like 10-15 minutes. That it would no longer want to start back up once it was hot. I have also checked for arcing of the plug wires, and also messed with the TPS which seems okay. So, now I'm kind of lost. The only other thing that I can think of is the valves being out of spec with the previous owner riding it HARD. Besides this the bike seems to runs okay down the road. The MPG seems like its a little on the lower side, but I'm also cranking 90-110 mph pretty anywhere I go with living out in county bumpkin....
Before moving further I wanted to get some more opinions. I'm currently a full time medical school student getting my doctorate, and got the bike to save money with my 80 mile school commute rather than driving my diesel truck. But, with having to replace a bunch of other stuff on it like front rim, wheel bearings, steering heads bearings, and whatnot. Its starting to become a nuisance and absorb a lot of time that I should be studying for boards with, and really don't have the budget to take it to a shop. I'm pretty mechanically inclined and have restored a bunch of old cars and older motorcycles, but haven't had much experience with this kind of motor or the PC3 (which I also re-flashed). I don't want this to turn into something big if not dealt with. Thank you again for any help. I really appreciate it.
