Bee is completely correct on everything he just said..and, yeah, the gen2's I couldnt ride long distance..this I can, and the ecu will be unlocked soon enough, NOT 2 yrs..
But, there aint a 100 hp gain in a ecu..
I've got a system on ine, no cats, and the a/f ratio is quite good for a open system..the restrictions still left by the ucu stock will not doubt go away after a tune, but, like the old song said, "aint no coupe deville at the bottom of a crackerjack box"
Be realistic in your expectations, and this bike is a great bike.
