Hello all, I want to share my mod for the throttle manage. The first think I do was on the grip, reducing the ratio at the cable base and increasing in the throttle drum. The second and third was closing the pair valve and O2 sensor eliminator. For the O2 sensor eliminator you need a 300 ohms resistor with a heat shrink and I found the connector in Cycle Terminal, You need a soldering tool to put the resistor on the connector ,two 4pin-HV.040 female connector 4.95 each one plus shipping. The connectors are located on the black cover back near the seat. on the left side the connector is the blue one, in the right side is black and is located in the middle of the 3 connectors. To close the pair valve hose I used two rubber hose caps from Pepboys.I can said the bike runs much much more smooth on the throttle manage on all gears at any speed and is better with the girl on back no engine light and if you have a warranty issue only need to removed it and connect back all.
