Joejo, here is where I'd start for diagnoses when you receive the replacement:
- Go into ECMDroid and make note of AFV value and TPS value, double check for codes.
- In ECMDroid go into settings and make sure "enable EEPROM burning is checked and that "optimized" burning is unchecked (you want a full .xpr burn to flash over data that is possibly corrupt.)
- Re-flash the full "race" .xpr EEPROM file
- Change AFV to 100 and perform a "TPS reset" for your bike. (hopefully you have been performing these on previous flashes)
- Take it out right away before it is warmed up, try your best to notice that flat spot and anything relevant that may give a clue to its cause.
- The bike will need a "run in" of about 20 to 50 miles for the tune to work itself out and give a change on the AFV (you want to see between 90-110).
- When you come back from your ride immediately check the engine temp values and make note, also is the fan running on shut off? try to see how long it runs.
Make note of all these things before and after and anything you may notice, it will all be a huge help in finding the cause.

No problem! We'll get your problem figured out so you can experience what all you've been missing with that dead spot! Probably will end up with a newfound love of the bike once it is right!
If a shift fork, gear or any other associated item of the transmission that actuates a specific gear is worn or chipped you could experience a slight skip in said gear that feels like a fueling hiccup or whatever you want to call it.Originally Posted by Joejo
When I rebuilt my transmission two of my shift forks(transmission has 3) were worn and third gear, along with the associated cog, had slight chips in them. This was enough to make the bike skip out of gear ever so slightly. The feeling was like the engine fueling or ignition spark skipping for a split second. Like I stated earlier at first I thought it was a fueling issue right around 3500 to 4000 rpm. Then I isolated the problem to only occuring in third gear. That was when I realized a transmission build was inevitable.
Hey chicken strip, was that a buell you had the warn tranny parts in if yes, how many miles was on it ?
I only speak Buell
Approximately 37k
Yep. Do that. Since the first thing you did was mess with the ECM, you'll need to get it back to where you started to diagnose the issue properly. Once you check for intake leaks and mechanical issues, check out this thread.

It's a Sticky for a reason
I had checked for intake leaks. I have alot of exp with turbo cars and trucks so I am fully aware of intake leaks. Haha
What will changing the Afv to 100 do?
Flashed a tune that buelltooth emailed me, ran fine with no deadspot. Afv was 90.3 no fan run on shutoff. Also no codes. This a.m. I went back in with ecm Droid just to look around and switched off all the check boxes for the exhaust valve. Not sure if that will cause any issues but I figured since I have the tune still in my email if I ruin anything I should be able to go back with no issues.
