Might not be the same two wires but read:

A tell tale sign if it is restricted is when switch the ignition on the power valve makes the buzzing noise and should buzz 3 times. After you finish this guide it will only buzz twice.

Aim: Unleash the power!!

Tools needed: 10mm sockets and spanners
12mm sockets and spanners.
Allen keys
Screwdrivers flat and/or cross
Long nose pliers
Strippers
Crimpers
About 100mm of 1.5 or 2.5mm cabel
1 male and female crimp (blue or red will do)
1 eyelet crimp (blue or red will do)
Patridge and pair tree.

Firtly take a pear from you tree and eat it......
Only joking

Right then!!

well first you need to remove seat, tail section and both fairing panels. Take your exhaust off.

A tell tale sign if it is restricted is when switch the ignition on the power valve makes the buzzing noise and should buzz 3 times. After you finish this guide it will only buzz twice :wink:

With the left side fairing off you can get to the power valve cap. remove the cap and undo the 10mm bolt. the pulley with the 2 cables on shud pull off after slackening the cables first.

To get full power turn the valve with a pair of pliers until the power valve is fully open. Turn the powervalve whilst you have a finger up the exhaust port to tell when its there. Then put the pulley back on but make sure not to move the valve when you tighten it up. put the cables back on and tighten them up to take the slack out of them. Now to check that it is fully set up right you can tunr the ignition on. the valve should do its buzzing opening and closing the valve three buzzes in total. When its finished the valve should sit back in the fully open position. The valve should sit flush with the exhaust port.

Now the electronic restriction!!

After taking off the rear seat unit you should see a wiring harness along the left hand side of the bike. Slightly back from the oil tank there are two dead end wires tapped to the harness, black/blue and gray. These wires cause the powervalve to close again at high revs.

Strip both wires and join them together with a male crimp . You can just twist them together but its not recommended by myself. Then with another piece of wire of the same thickness (enough to go from the two wires to the oil tank earth) crimp a female crimp to one end and a ring to the other.

Now earth your ring to the oil tank earth and plug in your bullet connectors!

Now when you turn your ignition on the powervalve should only buzz twice.

Put all the powervlave covers, exhaust, rear unit and fairings back on, and start it up.
