[Iori Yamagi]

Hi bro thks for replying..may i know what u mean by "the solenoid is kaput"?

[hi_sham32]

how do i know if my valve opens at higher rpm...?

Sometimes, your valve might not be working because the valve cable has snapped off. This happens when the cable wears off or your valve are stuck, resulting in the cable snapping off.

 

To check whether your cable are fine and the servo motor are working, stand on the right side of your motorcycle (not where your side stand is). Turn on your bike to neutral while keeping your eye on the valve cable, (between the fuel tank and frame).

 

If your turn on your bike to neutral, the valve cable will move. This means your servo motor are still in working condition. If you notice that the cable holder move but not the cable, that means your valve cable has snapped off.

 

I hope you get what I means.

yo today i checked liao. neutral gear. squat on the right side. and open throttle. yes the valve thing works. it moved, so i guess is just only cable snap? small problem right?

[HKM]

depends...if the black thing(valve motor) under ur tank moves,but ur rc valve at ur block area didnt,maybe snap or valve stuck due to carbon build up...like im going thru rite nw...sian...must go service...

If your power valve works/moved, how can the cable be snapped?

 

Its the cable that pull the valve open thus making it work.

 

 

Or you meant the valve motor worked?

 

What is the valve thing you're talking about?

 

[fastandfurious]

erm i not sure if snap or not. but i saw like hmm.. a knob? with a cable? and it moved a bit when i rev.. hmm.. i think im gonna check out other sp's liao.. see if different or not..
