this doesn't seem right.

Ghost pedals when the pedals are RFF and 50/50 and pedaling backwards makes the wheel spin.

 My NS coaster pro did also a bit of that when it was brand new (It wasn't quite as bad tho). What I did was that I slightly loosened the driver and tensioned my chain enough to avoid the ghost pedaling. It get's more sensitive after a while, you just have to ride it, or at least that's the what happened in my case. Now my hub won't GP no matter how tight the driver is Smile

 oh perfect. So it just needs a little break in time. Good to hear. thanks.

 Dude, thats nothing to worry about. It's a mix of chain tension, grease and just pressure overall. Don't worry about it. tup

 I just hate how the ONLY place it ghost pedals is where the cranks are when i ride, when I do foot jam whips and no foot stuff the cranks move down 90 degrees on me Frown

 What hub is it?

 I see. Ever take it apart?

 yeah yesterday, everything looked right, but I have limited experience with hubs.

 It's not super hard really. Just the same as anything mechanical. Clean, inspect, re-grease, and make sure it all fits nicely.
  • + 1
 that's what I did. Oh well, life goes on, it still engages and spins fine so I guess I'll live with it until it;s completely dead.

 Light it on fire.... or boil it. ....Nah I kid, don't do that.

 lol funny story about that ^^ we had a destroyed specialized hub/wheel.. coated it in lighter fluid, light it on fire and stuck firecrackers in the axle hole.. spun better afterwards hahaa

 Could just be some dirt in the bb but I'm no expert so don't take my word for it!

 im like 90%sure that you need new bearings in the hub
since i had the exact same problem with my bike

 My cranks are doing exactly the same thing. I think it's my hub though.

 maybe to much grease in your hub?
  • + 1
 might be, I used a really thin lube when I rebuilt it, but I used a little more than I meant to so it's not out of the question.
  • + 1
 hmm not sure, it's never happened to me and I packed my hub so full it was super quiet. if it's that annoying take of a crank arm, put a piece of old tube between your crank and spacer than bam, anti crank spinner

 that'll be my last resort if nothing else works

 The same thing used to happen to my NS primary. What it was is the driver pressed to hard against the seal and caused a shitload of friction, so i took it apart and theirs a little steel bushing that makes it so the driver doesn't press to hard against the seal and for some reason it had worn down enough that it did jack shit. Then i contacted NSbikes and after 2 months i finally got an email pretty much saying tough luck... So i thought fuck it and decided to get my dad to make me a new one. Since he's a machinist all he did was copy the exact measurements and made a new one on a lathe but a millimeter longer. Now my hub works mint and no problems what so ever... not sure if NS used a similar design on your hub though.

 probably pretty similar, the rotary single (my hub) is just an updated primary, so that could very well be it.
  • + 1
 Ohh you have the 2011 rotary non pro, that hub is actually identical to mine (2010 primary SS) except yours has different bolts and colour. But yeah, I'd get on fixing that cause mine just got worse over time neglecting it.

 Too much chain tension or over tightened hub?
  • + 1
 might be the bearings in ur hubs i had same problem
  • + 1
 Your hub is probebly too tight.
  • + 1
 as in cones or bolts?
  • + 1
 what do you mean...
  • + 1
 do you mean the cones are too tight, or do you mean the axle that hold it in the frame is too tight?
  • + 1
 I would say the axle but you could check both and see how it goes...
  • + 1
 I'd say the cones that tighten the driver and bearings, therefore the driver can't spin freely which causes some drag and ghost pedaling.
  • + 1
 chains too tight, hub might need a rebuild
  • + 1
 and it might be too tight because i notice a tight spot and that seems the spot it makes the wheel spin
  • + 1
 already re built it, helped a little bit. when I loosen the chain it turns the crank more. When i get the chain to perfect tension it doesn't move at all.
  • + 0
 loosen your chain tension
  • + 2
 loosening the chain tension makes it worse.

 It shouldn't. What you're seeing there is drivetrain drag. Something in your drivetrain is causing friction. Make sure everything is assembled and torqued proper.
