Power valve

What's better power wise pinned or servo as my bikes pinned but I have no idea how so just curious what give more power

finnerz89

No difference in peak power, but using the servo you'll get a broader range, so you'll have better low and mid range. Obviously it depends on exactly where you've pinned your power valve

vtrn_raptor

I have no idea as it was like it when I got the bike but the servo is still their and all the cable connections to the power valve are attached but the servo is unplugged

finnerz89

Mine was pinned when i bought the bike, reinstating the servo etc made a huge difference for me

Pinned all the way. You gain everything and lose nothing.

Unless your CDI is restricted, that'll cause the valve to shut after a certain RPM.

Zeeltronic gives you complete control of when the valve opens and shuts, allowing you to really get the full potential of the YPVS. Big gains to be made with a custom ignition.

So keeping it pinned is better

I would try it with the servo when it's pinned there is no power at low revs
Perhaps it's unplugged for a reason I would take the pv out an clean it toke sure it's not sticking then connect the servo up an try it

Calum

@vtrn_raptor Jeez I really messed that up. Sorry no, Servo all the way.

Don't pin use the servo. I don't know why I said pinned sorry.

Servo is much better.

Jens Eskildsen

Servo for sure, best of both worlds.

vtrn_raptor

I would but I have no idea how it's been pinned took off the cover on the left side and all the cables to the pulley are still connected so I'm really confused lol

Mightyman

@vtrn_raptor can you hear it trying to do it's cycle when you turn your bikes ignition on?

vtrn_raptor

Not sure I'll check when I'll plug it all in and check when I'm home

Sorry to butt in the thread, but has anyone got any idea why... when I connected up a working servo to the plugs it was completely dead? No cleaning cycle whatsoever, cables not connected so no load on it. Just not working at all. What's the most likely causes? Could it be a CDI issue? (03 DTR) I want to put a servo on desperately. Cheers.

Calum

Yeah motor can be dead, or faulty cdi.

Multi meter on the plugs will tell you.

@finnerz89 how did you manage to wire servo up pal

Zrako

Or overtightened servo tensioners . I was setting them on and if they are not set properly , the servo will not reset when ignition turned on

ijohney123

@Zrako have you not had to rewire servo ?

finnerz89

@ijohney123 just plug and play mate. My servo was unplugged with the cables overtightened so the pulley didn't move

Zrako

No , I had a good conectors on bike so when Im rebuilt it was just plug out - plug in . Try to loose the tensioners a bit . There is a "how to" in haynes manual

vtrn_raptor

Well I've took the servo and everything off made sure wasn't over tight then plugged back it but does the cleaning cycle really fast and doesn't move at all with the bike on any ideas
