I've got both the gray wire disconnected and the TPS unhooked and love the way it runs. Why do you say NOT for trail riding on the TPS?

The TPS helps in low speed technical riding only. It is a hinderance for steady throttle/ speed street riding. If you dont ride nasty technical terrain you may never notice the advantage.
Thanks for the tip!! I will have to try that out.......!!

There is a spring that richens and leans the mixture depending on how you are working the throttle.
For example, when you close the throttle from high rpms it richens the mixture to avoid backfires.
The problem is when the throttle is held steady the spring leans and richens the mixture chaotically, causing the engine to surge. It's not really a miss, its a surge-on, surge-off situation.

I would try cutting it first and move in small steps to see if you can fix the problem before trying more involved measures to solve the problem.
In my experience (00 WR and 04 WR) they both had a stumble on constant throttle openings. I didnt notice if much off road, mainly cruising on dirt roads when the throttle was constant, it would surge and stumble, highly annoying when traveling any distance
