Reply With QuoteTps reset
2009 Buell XB12Ss, 24k miles, Drummer SS, EBR ECM, open airbox:
Sometimes, when I go to down shift and I blip the throttle to rev match, the motorcycle will not rev up, but instead it will choke and fire off a little pop through the intake. What, if anything, should I be looking into?
Tps reset
Followed the 2009 TPS reset procedure. Key on, run switch on, throttle open to close X 3, off then on. Symptom still present.Originally Posted by BuellyBagger
You say (Occasional Choking ) Do you think it is rich or lean ? What do your plugs look like ?
Throttle body clean?
My engine can sometimes chock for a second when I shift from neutral to first gear, and sometimes when I start releasing clutch lever at 1st gear. It even stopped once.

The EBR ECM is matched up for my exact muffler/air filter combo. With the exception of the occasional occurrence of above mentioned issue, the bike seems to run smooth. I don't have a compelling reason to believe that it is running rich/lean. I installed new, OEM Harley plugs like 400 miles ago. The old ones seemed consistent with normal wear, dark brownish, some charring.
The throttle body looked clean when I had the air filter off when I was changing the spark plugs.
How often do you use injector cleaner ? Did it have these symptoms before you changed plugs?

Never.
Plugs from our emission strapped machines should be light tan on porcelain and light black ish around metal base because of rich idle. No charring that’s oil. Detonated if material speckeled on plug from pistons..
Super lamen run down
Oh yeah I know spark plug reading is a lost art but I think some people should pick up on it on this forum, it is your heart beat of your bike and boy does it help with diagnosis of a engine. Plus engine vacuum but that’s for another time.
