When I take my bike out on a fast road or even a hiway the engine speed surges up and down a bit. Not alot, but enough to irritate my sense of perfection Someone said the TPS was causing this an the simplest way to fix was to just simply unplug it.....and it seems to work Why does this TPS exist in a non-FI engine? What does it do? or, more simply stated, what will I be giving up? Will the bike be slower?
