Shifter question

[Ace Rossi]

Okay here goes! First off I dont need to be told that E-shifters or air shifters are not legal or do I need to be ridiculed for bringing up the idea of wanting to toy around with one so with that said, my question is, has anyone ever had one, tried one, or know of any one that has OR is playing with one specifically an "air shifter" made and sold by Sharp Shifter in New Zealand?
I'm having sort of a rough time getting the shift actuator mounted with enough space to line up with J arm. Tried to install it per instructions (no room) and also on its side which gained room next to the seat but still not enough room for shift rod to line up.
So I was wondering if anyone had past experience with this shifter or know of anyone that has!
Thanks and no this is not a permanent thing but since I acquired it at a very cheap price, i thought I would try it on play days!

Ace,

Any luck getting it situated?

I'm not sure if anyone is using that system (I've never seen one), so you may not get responses. I looked into getting one years ago -- it's a very cool concept, but I decided it would just turn into a time-waster at the track.

Can you post some pictures of the "situation" so we might help with ideas to get it working?

Thanks Randy but nothing yet! I did alot of searching EKN last night and was able to find sone very interesting post regarding Sharp Shifter and some contact info for guts that have used them with and without success! Ive sent a couple emails out but no replies yet! Those guys may even be out of karting now, who knows!

[Randy Mckee]

Yeah, hard to say if it's still supported. There's a lot of fab guys on this site that can help out, so do the pictures if you can and I'm sure you'll get lots of ideas to get that thing mounted.

Not interested in the ME shifter but good news is one of the contacts wrote me back and has a bunch of stuff from Sharp Shifter in storage on his kart from what I understood and will be sending me info and pics.

I wonder how much power it takes to run the air compressor of the axle? It has a very small tank so you would think that compressor will be running almost continiously.

Brian to my understanding the compressor has a pop off at 80 lb so although its turning with the axle, id say very little effort is needed!

The problem I'm having is mounting the shift actuator and still having eniugh room for lower hose, getting the shift rod in line with the J arm and not being in the way of my leg since the actuator has to be able to swivel since the J arm moves in a slight arc.
After studying every option, i came up with what I think might work but here I am, asking you guys first!
What if I were to mount the actuator flat versus vertical and beside the fuel tank which is out if harms way of everything AND rather than run a rod all the way back to the J arm which has to clear the side of the seat, the lower radiator hose, and not to mention reverse the J arm from being in the up position to the down position which could be below the chassis, I would mount the actuator rod directly to the original manual shift lever right along with the original shift rod using a heim joint on top of the heim that is already used? In other words, use the air shifter to shift the original configuration rather than shift the J arm alone! This could also be removed ( if not allowed) simply by removing two bolts and unplugging two power plugs on the actuator and as a back up IF the air shifter failed for whatever reason!
Yes or no?

run your bottom hose over the top of the motor and down onto the fitting.
