Anyone here that has a Vortex ECu ever noticed how touchy the throttle is without the stepper motor connected? I'm hoping to add some extra resistance to the throttle tension, anyone have any BTDT? It's really touchy when I'm riding over rough terrain, likes to buck and surge and I get arm pump trying to hold the throttle super steady.

While we're on the canister topic again, is anyone experiencing carbon/charcoal spewing from the canister? This crap ends up on my pant leg and the right side of the bike/frame. Is this normal?

BTW, Dunefreak, how pissed are you that Champion closed their doors? Seemed like you picked up your bike right before they shutdown.

I use a Kaoko throttle lock to provide a little tension on the slide. It removes all unwanted movement.

Sounds like you could have fuel in your canister. Do you keep it about an inch below the neck when you fill it?

Yeah that kinda bummed me out about Champion, but it wasn't their fault. Greg, the owner, did everything he could to try and save it. I'm just glad I got the bike before they closed, otherwise I would have had to drive to UT or CA. I got a good deal so I'm happy. Carter picked up the KTM franchise so I have local support again.

Do you already have a smaller throttle cam? No big problems for me with Vortex in rough terrain and I do have a smaller cam.

Wow, I bet that's it. And no, I don't keep it an inch below the neck. I fill that b-i-t-c-h up. Not anymore. Now what?... (1)canister just needs to dry out or (2) do I drain it or (3) use this as an opportunity to yank that sucker off the bike. Thanks for the feedback.

You can try to let it dry out, but I'd just yank it off at this point. They take a while to dry out. Sometimes they deteriorate once they become saturated. All the tank pressure that builds will keep pushing out whatever fuel that's in there. If you look at the vent whole just below the fill neck, you want to keep your fuel below that point even without the canister otherwise it will just puke out and your wasting fuel. You need to allow some space for expansion of the fuel when it warms up.

Does anyone know of a paint to use to touch up the grey on the engine cases. Thanks.

I have the 400 cam installed already, but the throttle pull is really light still.
I might try to find another spring to fit on the bell crank on the t-body.
Thanks Dirt Jack, if all else fails I'll look into the friction lock.

Mine is also very touchy with the throttle. Let me know what you come up with.

Ditto. Fine on the black top but real twitchy offroad.

There has not been any recent updates on the Vortex unit. Are you guys still happy with your purchase? Is it worth the money? Where are you getting the most gains? I have been looking at getting one, though my bike runs great I would like to smooth out the bottom end. Where does the handlebar selector plug into?

I pulled the housing off and had a look inside the bell crank area of the t-body.
Looks like I can drill a small hole here and there and add a small spring.
I think the ride by wire stepper motor added resistance with the old ECU system.

An ECU flash won't help this problem as far as I can tell.
