Rocket fixed. It was the stepper motor

[Navigator]

gasket , im pleased for ya,,, 8)

I thought of your post as I was riding home. I was pretty angry at Triumph and the dealership but this one was a real stumper but Triumph jumped in and the tech worked hard to get it resolved.

I am back to really enjoying my Rocket and am glad you are too. Happy endings. Now if we can just get George's and Dragonfly's fixed.

Glad its sorted for you.

Fingers crossed it stays sorted.

TPS replacement and idle stepper motor can be repaired/replaced without removing the throttle bodies.

ndgns1- Look above the the stepper motor, you'll see a set screw with a locknut, you can adjust your idle with that. Then install the plug back onto the stepper motor. That way the ECM will still see the circuit and not fault. RiderRocketman did a good write up with pics on this in the How-To section. He removes the stepper motor, I didn't. If the motor isn't moving, it doesn't hurt anything where it is now.

the TPS and Stepper motor does look like its removable w/o removing the throttle bodies.. but the manual says you have to remove the throttle bodies... I just wasn't sure if I was missing something..

so now I will prob be looking into doing a stepper motor and/or TPS R&R myself...

Good news Mike, see you there...

Mike...

Maybe its time for you guys to find a TPS from another bike that will do the job.
Didnt someone say their was one from a Suzuki that was the same?

Get packing Mike

The one from the GSXR 1000 is suposed to be the same one but ck. it out to be sure..

Must be the primary...When I discussed the TPS with both the service department and Triumph America, they just referred to TPS and didn't stipulate a primary or secondary. I didn't know there were two of them. One thing for sure, I am not going to make any more suggestions to the mechanic. I might have slowed things down by suggesting it over the phone. I think they were trying to be accommodating because I live 90 miles away. I'll bet it was the stepper motor all the time and not the TPS.

I really hope that fixes it Gasket,but the stepper motor should only come into play at start up and before the motor is warm. Didn't you have crazy RPMs while riddin? :wink:

I had crazy RPMS as well during riding..

it seemed it would get stuck at 1500rmp, then 2000, then 3000rpm all within about 15 minutes of riding.

I would cut the ignition on the bike, and things would settle down a bit.. but after about 15 minutes of riding.. it would do it again..

Plus I noticed while I was riding down hills and using engine braking. the bike was really jerky.. surging, then slowing

after unplugging the stepper motor, I havn't had any issues at all...

for something that is just suppose to control the idle and cold morning warm ups.. it sure seems to f'k with general riding as well..

like I said.. unplugged and problem free for about 2 weeks now.

George, that is EXACTLY what mine was doing. I'll bet it is the stepper since you don't have the problem when you disconnect it. If you take a look at the thing, the stepper arm moves in and out, engaging the throttle linkage. (I can't find in my manual what the correct nomenclature is so I'll call it throttle linkage). The amount it moves is in milimeters so it doesn't take much to make it go squirrely. Good luck.

So then the bad stepers are over driving the linkage to the point of gettin scary on the road????? :wink:
