Default Tps replacement

Hey guys, my bike has been running kinda rough lately, stalling at stops and with the clutch pulled in. I replaced the throttle body boot/adapter, whatever you wanna call it. It helped a lot, it just still stumbles a bit around 1700-2000 rpm. I'm probably going to replace the pts and was wondering if there is any kind or resetting or calibrating I need to do when I put the new one in, or is it just a plug and play? P.s, the throttle body was just cleaned and the battery terminals are clean and tight. Thanks for any help/suggestions

Periodic TPS calibration is not required. If you replace the TPS it should be recalibrated. You can replace the TPS on your own & see if it cures your issues, you'll need a digital wrench (dealer) to make any adjustments. You mentioned your battery terminals are tight-what shape is the battery itself in? You can get a TPS at NAPA
part # 2-19187, Victory doesn't have a part # you have to get an entire throttle body.

The battery is pretty new, I just ordered the napa part a few minutes ago. Once I get it and put it in I'll see how it runs. I was just wondering if there was anything else that needed to be done besides just putting it in

You can also try the TPS relearn-sometimes if the battery is disconnected the ECM needs to re-learn the positions, it can't hurt anything to try.

Key on Switch on Engine off
Rotate throttle to wide open slowly
Hold throttle open for slow 5 count
Let throttle snap shut
Cycle kill switch
Start bike

Yeah I've done that before, the bike has been running rough for awhile now. I'm gonna put the sensor in and see what happens

So I'm just going to ask the simple question ghost rider before spending money and labor. What gear is the stumble in? Tabs were cleaned when you replaced the boot? Fuel system cleaner run through it like seafoam? What mods you got, air exhaust? Wires replaced or not? Maybe I'm just catching up with your problem.

Tim, it stumbles in any gear between 1700-2000 rpm. It isn't too bad if I ride like a grandma, but if I get on it a little (which I like to do) it stumbles really bad. The tb was cleaned less than 50 miles ago. It wasn't too dirty, last I cleaned it before that was about 29k, now it has almost 32k. I ran a bottle of fuel system cleaner thru it at about 30k. It has rpw slash exhaust and a k&n air filter. I don't think the air box is original, but I think it is a victory air box. It's hard to explain. It may be from a different year Vic. Idk all modifications to the bike were on it when I bought it.

I don't want to insult your riding skill, just trying to understand how the stumble is occurring. Your shifting points are what on average and do you let her sag below 2200? 2500 is the common happy rpm and below 2k you may hear a lugging lashing as she try's to get above 2k again. Unless your saying on the acceleration out of 1st it's stalling through 1700-2k. If your hitting good shift points I'm not sur how your getting down to 1700rpm. Again no insult intended, have talked a few folks through unintentional lugging and problem fixed. Everyone has their shift point but for trouble shooting I found shooting for 3500 to 4500 out of first gives good answers.

Didn't catch last time plugs were out how were they and possibly wires replaced? Our bikes are 10+ years old now. Lol.

Did you open up the air box drilling it or remove the screen. Inspected the filter for debris? On my 04 I had opened up the bos a little and one day sucked up some debris blocking the volume a little. Of course going to the ness sucker fixed that. Lol

It has been doing it for awhile, before and after cleaning intake and filter, new plugs and all that. I have never replaced the plug wires, I should probably put that on my list of things to do. I usually shift around 2200-2500. It stumbles on the way up to shifting rpm. I've tried shifting at different points, but once it gets to 1700 it will start stumbling. That's usually only in first gear, I'm above that rpm the rest of the time. But like I said, I've tried shifting at different points, so I've had it stumble in the other gears. I know that riding in low rpm isn't too good for these bikes, so I gave up low rpm shifting and went back to my normal shifting

Well for shift points your right about higher rpm, I don't let it get below 2k without down shifting because they just don't like lugging and chatter like a thrashing machine. My target cruise rpm is 2500-2800 up to 3200 with the powerband starting to dwindle down around 5k. Before I started chasing anything eels I would grub the shift recommendations from your owners manual and try those for a whole and replace those wires. I've been knocking out some miles today on my 04 and I could classify it as a lil sluggish around 1800-2k when I hit near wot. How did your plugs look when you pulled them. Or, if you have 2k on them how are they now?

Now, about that air box. Left, I can't make out the pic. Have you replaced it with a ness KN out similar or is stock box on it?? I know you have KN on your sig but wasn't sure stock box kn or ness big sucker replacement. Wires, order them now! Rule out what's sure to need replaced. 11 years? Yes.
