I went for a brief ride yesterday since the temps got near 50 degrees and had an unfortunate incident that might be of general interest.? While going about 40 MPH and about 2 miles from home, my Vision suddenly went to wide open throttle on its own.? Not knowing what had happened, my instincts were still good and I had quickly pulled the clutch to avoid colliding with the car in front of me.? However, the engine was screaming at over 5500 RPM and I had to use the fuel cutoff switch to regain control, as I got off the road with a very narrow shoulder.? After getting my breath and heart rate back, I tried a re-start and the engine immediately went to full throttle again.? At first, I thought it might be a problem with the newly installed fuel controller from the recent cam upgrade.? However, this was not the case - the throttle cable nut had backed off and was dangling on the cable.? I spoke with KevinX who said that he had seen a few other incidents like this recently.? Kevin suggested applying some lock tite to the nut.? I assume the nut is backing off due to vibration, though my Vision runs fine - no excess vibration noted over 9000 miles. ?

I am attaching a couple of photos of the area behind the right cheese wedge where the cable is located.? The photos are the same view, just a bit closer and with a red arrow to indicate which nut (the rearward one) backed off.? Since Kevin has seen this on other Visions, I thought some may want to know about this and possibly check their bikes for loose connections.? No, I won't say check the bike for 'loose nuts', knowing what the comments will be? ? Hope this is of some use/interest.

?

I'm thinking Victory definitely needs to be made aware of this in writing. This is a potential life safety issue that could result in future deaths. Imagine approaching a red light at a busy intersection and suddenly, without warning, going into full throttle mode. Me thinks a recall may be in order here.

can we dub these the Harley nuts since they seem to be the only ones that vibrate loose...?

seriously though, an inspection and tightening of them IF they are loose should solve the issue immediately. The design is positive pressure from both sides if tight and they should never vibrate loose. They would have to be loose to start with for the lower one to run itself off and cause the issue. For your own sanity though, a touch of loctite should give you piece of mind.

"Harley Nuts".... Now that's funny. I suspect a great potential for that to stick.

Loctite makes a med strength thread locker. Looks like a good place for a drop. OBTW where is the "fuel shutoff switch"?

Honest officer this is a known issue....LMAO. I went out and checked the cable on my bike, no problem showing yet. Still tight. Hmmmm, wonder if Victory will do a recall on this? Seems like an easy enough fix.

yeah, right after I posted this question I figured that was it. I just never called it a fuel shutoff switch. Well, not too bad for a Monday. thanks.

If you ever have read your manual on page 35 of the 08 manual says report safety defects to NHTSA there is phone number and address so if you feel there should be something done call them.

As far as your nut goes I wonder if it was threaded wrong or striped when it was first tightened at the factory.
Its very nice to have Kevinx around to help us. Thanks Kevinx for being one of the good guys

Wow, such an old post. I never saw, and I am so glad it got bumped to the front again.
Thanks not only for the heads up, but the pictures. I know right where to look now.
You got to love the internet.

More like 60% false. The first year is the only portion that falls under the MM Act. After that it is a insurance policy, and exceptions based on modifications are clearly spelled out.

I was more referring to the direct confrontational wording of his statement. "If you add anything..." is just wrong, and is an unfair attack on Victory.
Using non-factory but industry accepted oil, filters, tires, brake pads, etc has no impact on the warranty, where as adding some electrical components for example could.

Gotcha, and in that case you are 100% correct

Irrespective of any legal arguments, a warranty or service contract is of no value to anyone that is dead or injured.

This is a simple fix that might prevent some of us from wasting any more of our "9 lives" than those that we have already squandered yelling "hey y'all watch this"!

The thought of having to contend with a stuck throttle in traffic, with the added distraction of the wife slapping me on the helmet, and screaming is blood chilling.

Preventative maintenance, it's a no brainer.
