1st of all, it appears as though you have a 954, not a 929.
2nd, welcome to the world of "codes" and electrical SNAFUs.
Now that's out of the way, let's get started; 954s are fine-tuned machines that get maximum output (factory) from the HTEV. Yes, the servo motors fail. Nearly ALL do. If the cables haven't "jumped" the groove and the drive motor(s) have stripped guts, then I recommend DELETING the HTEV, cables, and airbox flapper altogether. If you don't purchase (or fabricate) a ServoBuddy (available on ebay and other places), your 954's MIL (red lamp on gaugepod) will be illuminated, as it's looking for feedback from the system. You don't need to be a Master Builder to perform the delete. BUT! I HIGHLY RECOMMEND getting a Honda Service manual (if you haven't already), and follow the instructions to reset the code(s). Plus, you'll have it for future issues
There are different places that sell "through" collectors. If you don't want to spend the loot, you can alter yours and leave it in the WFO position. Exhaust tone will be different, and some say you'll lose power somewhere in the RPM range. BUT! Most streetriders don't use more than 25% of their bikes' capabilities, so surely that modification will be barely noticeable and probably won't lessen riding enjoyment (as much as a red LED staring you in the face and a constant clicking noise anyway).
I performed the aforementioned "mod" on my RR2, and have had YEARS of enjoyment and ZERO issues relating to the (deleted) airbox flapper, (deleted) servo & HTEV, and NO MIL illumination.
