Just to confirm the pulley faces outward an the holes are on the left
( it's not going in a Dt frame so it's best to check before I weld the bracket )

Are you spare wires
One black yel bullet
An other 2 one brown one black both live in same connector ?

If so you need a 3 wire servo
5 wire servos also need a contrôlér but 3 don't

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

@andrewj1680 said in Any ideas how i can run my ypvs without a battery:

@rogering according to the wire diagram on the 3 wire servo there should be black and yellow to cdi unit so this would be a live, a black should be earth put a fuse and then looks like brown is a remote earth

brown will be live
on yam wiring black is earth brown live

it connects to wires coming from the cdi
black/yel wire with female bullet

black wire
brown wire
these live in what looks like a double female spade plug

@andrewj1680 said in pinning power valve parts needed:

You could always just stick a big washer behind the bolt that runs through the middle you can lock it off that way which is what I have ended up doing today as since having port work and the power valve modded it kept moving a little over fully open

I ve bought the servo kit I can use the standard parts to pin it now
or if I can get the servo to fit my frame I will use it
(the dt engine is in a different frame ) its gonna be a mission to get the servo to fit I wanted to mount it under the tank but the cables are too short
not sure it will be worth the hassle

@Louis-James said in Photo of pv servo needed:

Thanks
Any chance you can take a close up pic I need to see how it mounts to the frame

Any chance some could post a photo showing where the servo mounts to the frame

@dan28
that cloud / pic attach tool is awesome thanks calum
