I know it's been a few months since anyone responded to this thread, but I just had an interesting experience with this mod. I own a 2007 SV650 like the one pictured a few posts above, with the single-screw-mounted TPS. Since I don't own a set of security torx bits yet, but I had some time on my hands, I decided to do a walk-through of the mod so I would feel more comfortable with it when I had the right tool for the job. I placed the wire into the diagnostic plug as demonstrated and began trying to find the fuel-dump point indicated by the dash moving upward. It did not happen at 1450 RPM, as was predicted. I eased the throttle on some more until I reached 3000 where the OP wagered it would happen, yet still the dash did not move. So, up I went, past 3500, past 4000... then bang!!!!!! The dash did not move upward until I reached 4500 RPM!!!! Until this time I had been experiencing the same hideous lack of fine throttle control since I bought the bike back in November. I loved the bike and wanted to keep it so I was lucky to stumble across this thread while searching for a clue. Ok here's the weird and interesting part. Since I did that yesterday and simply put the bike back together without actually having performed the adjustment, THE BIKE HAS BEEN PERFORMING BEAUTIFULLY!!!
The jerky low-speed throttle response is gone!
All I did was insert the jumper wire and rev the bike 'til the dash moved on the display and then put it back together. It is so awesome to finally be able to just ease onto the throttle when coming out of a corner and smoothly accelerate.
I can ease on and off the throttle the way it was meant to be and not look like some novice on his first bike (cuz I'm not one). I was so tired of having to feather the clutch to compensate for this irritation. I can't explain why the problem resolved, I'm just thrilled that it did! Just thought I'd share. Ride On......
