plus it makes a change from the usually subject

Honda RS250 Power Valve check, there are 10 steps to heaven

It is important that you understand the difference between a Woggle and a vibration.
A Woggle is a slow back and forward motion.
A Vibration is a very fast back and forward motion.
If you are still confused ask your Wife/girl friend/partner, she/he will let you into the secret.

STEP 1
Completely slacken the low & high cable adjusters at the P/V motor end.

STEP 2
Operate the P/V motor to high & then low, several times with the checker unit/kill switch (RS250 1999 by disconnecting/reconnecting the orange power jet carb plug), then set the P/V motor to the high position (leave the kill switch in the On position)

STEP 3
Adust the low cable (at the P/V motor end) until the pulley starts to Woggle (slow back and forward motion).

STEP 4
Continue to adjust the low cable until the pulley stops Woggling (slow back and forward motion) and starts vibrating (very fast back & forward motion). Lock the low cable adjuster nuts off.

STEP 5
Adjust the high cable (at the P/V motor end) until the pulley starts to woggle

STEP 6
Continue to adjust the high cable until it stops woggling. Turn the adjuster one half turn more and lock the high cable adjuster nuts off.

STEP 7
Set the P/V motor to the low position (leave the kill switch in the On position), the pulley must not be vibrating it should be still.

STEP 8
Set the P/V motor to the high position (leave the kill switch in the On position), the pulley must not be vibrating it should be still.

STEP 9
Check that the P/V linkage arms meeting the P/V stoppers on the cylinders,both must be touching.

STEP 10
Sitback, have a cup of tea and talk to anyone that will listen about the finer points of Woggles and Vibrators.

NOTES
#1 All the above directions are for setting the Power Valves with the HRC P/V checker unit, which is connected to the wire harness plug situated under the clock mount bracket. Connect the valve checker to the white plug with the RED & GREEN wires.
[B]DO NOT CONNECT THE CHECKER UNIT BATTERY TO THE GREEN PLUG WITH PINK AND GREEN WIRES OR THE WHITE PLUG WITH THE BLACK AND RED WIRES./B]

#2 The Power Valve linkage rods, stoppers and cable adjusters must be set/checked to/for the correct lenghts and positions (as per the HRC RS250 manual) before the P/V check is carried out.

Hope this helps :wink:

Thanks for that Tel,
