Brand-new TPS- bad from the factory?

2003 DL1000

Hey guys,

I have had an unholy bitch of a time with my TPS ever since I installed it two years ago. It's never EVER read correctly, no matter how much tweaking I do to it. The bike has only run for about 2500 miles over the past two years since I installed the new TPS, and I'm reasonably confident that it's the source of all my fueling and fuel economy woes (I've bought and installed stock pipes and unplugged the power commander to no avail, still the same awful popping and stuttering and still 35 mpg).

EVERY time that I think I have it, every time that it starts to come off of the center line at around 1500 RPM (and I tighten it down and confirm it does the same after tightening), a few throttle turns later and it's back to sticking on the high hash mark. Is it possible or likely that my TPS unit itself was bad when I purchased it? I guess anything is possible, but does it seem likely? Has anyone else had this kind of frustration in trying to tune their TPS?

Garage
The most common problem with a new TPS is not taking the old O-ring off the throttle body and adding the O-ring on the new TPS in the mix. A double O-ring causes problems.
aTuWitty and marcham like this.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Well, screw me sideways, that was it. It's now perfect. Two years of frustration and it all came down to one tiny little seal. Oops.

Thanks, Pat!
