This was mounted on my bike when I bought it. The bike was working great except the engine was occasionally cutting out and I removed it to see if that made any difference. The engine stopped cutting out. I suspect one of the connectors wasn't seated properly, but who knows. I like things as simple as possible and the bike runs fine stock, I don't need it to be faster, so i never put it back. The only think that was attached to the bike was the "Fuel injection module" the other stuff was in the box it came with. The other stuff appears unused. Make an offer.
