06 xb12r stuttering

[jtown125]

I have read until my eyes hurt. I have looked at almost every suggestion and opinion. I have changed both spark plugs(iridium ngks), new racing wires, new o2 sensor, checked all the grounds. I have done 3 different tps resets and it seems to help for a little bit but a couple days later it goes right back to doing that misfire in open loop, anything above 3500 it runs like a champ. This is annoying me to no end.

I ran the 10 guage ground wire someone suggested in my last post, (no help). The only other thing I have read and not tried is adding and changing the amount of fuel being dumped in. I just wanna know if I have not read enough or if there is something I am missing. I understand that this is a really common problem, but I want it fixed. So any help is apprecaited.

its not an intake leak either.

If there are any tn/ky/nothern georgia or alabama riders out there hit me up and tell me what your afv is set at. I ended up just messing around with it and set it to 105 instead of 100 and it ran "better" still stuttered but not as much. less than 10 times during a 20 minutes ride.

Have you done ECM Spy OR any mods of any kind? Exhaust is it Stock also? The Hiccup OR misfire,What Rpm is it doing Exactly? Year of Bike Looks to be 06-07 XB12r Maybe 95/on the Afv,Some bikes work better at 110. You will need to remember the stock settings.Might have to play around with it till you get it where you want .Have you Data Logged a ride to see the area so you can use the info, to help solve your problem area? Whats the numbers on TPS-at Idle?Post up when can.Good luck .`Jimi

bike is stock. minus breather mod. cruising speeds on hiccup. 1900-2900 (more definite on higher side of those rpm's) and then that always hiccup at 55-65 no matter what gear you are in. Not exactly sure how to data log, im sure im just collecting info for each ride and determine which one is the best for my condition? tps at idle is like 6.3 % and 5.5 degrees. (ill have to double check i have done it so many times)

does your throttle body got a lot of dirt n grim in it from before the breather mod.Has it been clened since?

i don't think its been cleaned. but i rode it today around 200 miles and the catch can didn't even have that much build up in the breather mod
