Default Loud backfire, bike stalled and I almost fell off bike

Hi,
Was riding around 40mph, shifting from either 2nd to 3rd or 3rd to 4th. Bike backfired real loud and stalled out. Bike fishtailed (I really don't remember braking at all considering I was at 40mph and stalled) but kept the bike upright (Thank you GOD!) Brought to the shop and left it there to check out why it stalled after backfire at 40mph.

Any ideas anyone?

Could I possibly fishtail or my brakes lock up on their own if I don't apply any brakes?

Thanks all!
Good to be alive...

Well, if the bike stalled and you were doing 40mph, I'm guessing the rear wheel locked up because you were in gear with the clutch out. I can stall my cross country if I blip my throttle, like I used to on my old softail. Hard habit to break for me. Doubt they find anything wrong with your bike. Good luck though!

When your bike is running idle what RPM is she running ? Yes maybe you have to try to shift / ride at higher RPM ?

Let the mechanic ride your bike and sure there is nothing wrong.

When your bike stalls you must engage your clutch .

Welcome to the near miss Victory club.
Wife and I are both members.


Some Victories do this. Though I have not heard it associated with a backfire. So yours could be something different. They may find a loose battery connection for instance.

There is a problem with some Victories that Ma Vic isn't talking about .
Some Victories are very sensitive to having the clutch pulled in too long during a shift. Mine stock seemed to fall in that category. Almost killed me last winter. It was real close. It's not stock anymore. That event prompted me to get off my wallet and start looking for a solution.

Some are sensitive to blipping the throttle to speed match the trans during a down shift. My wife's XR falls in that category stock so we added a pcv and a timing wheel to her's too in the hopes of solving that problem.

Avoid both of those behaviors if you have one of the bikes that have this defect, you'll probably live longer.

Both of our bikes seem to run much better and feel much more unlikely to stall after installing the PCV and the timing wheel. However since no one except Victory really has a grip on the problem it's a guess as to if we have really fixed it by adding these items.

My wife isn't about to start blipping the throttle on down shifts to test if the problem is fixed. As you found out these bikes tend to lock the rear wheel when they stall and she has no desire to go down to prove that the bike isn't really fixed. The several stalls she experienced were enough to convince her she didn't want to take a chance on it happening again. Now she just down shifts her Vic without speed matching and the bike no longer stalls and locks the rear wheel. That makes her happy
When she is on her HD's she switches to HD mode and shifts like a normal person without any fear of them stalling. That too makes her happy When she's happy my life is better

Myself I'm not near as smart as my wife so I may try this winter to see if I have actually solved the stalling problem on mine. If not I have a Lloyd's Idle air valve I will add to see if that in addition to the other parts will actually solve the stalling during slow shifts problem with mine.

Anyway don't be surprised when the dealer says they can't duplicate the problem if your bike has these issues. They never can.
If they can't find anything concrete to point to, try not speed matching (blipping the throttle) and not holding the clutch for an extended period of time during a shift ( make sure if you start a shift you complete it in a timely manner) and see if the problem disappears.

If it does help, drop Victory a letter about it, tell them what you honestly think.

There is also a federal vehicle complaint form that can be found on line and filled out, don't neglect that. This is really a defect even if Victory would like it to be considered a feature. It's dangerous and needs to be addressed

After it stalled were you able to get it started again , or did you have to trailer it ?

Default Hi

I started my bike right away with no problem and drove it to the repair shop. They are a Victory dealer and that is where I bot my bike.

I'm not sure what some of you are saying when you mention "Blipping"? Can you explain this?
Thanks,

I was upshifting the bike into a higher gear when this happened, not downshifting so would one need to blip going into higher gears?

Blipping is when you crack the throttle when at a stop sign to sound kool . Some blip when downshifting to make the shifts smoother , I tend to rev match which is a controlled throttle and not just blasting it open .... Which often results in a lean stall ...

I have a Gunner, And the trans will do funny things, Like when in neutral at a light hit first start to accelerate and it will slap back into neutral , Also this has happen to me, Up shifting from second to third, It didn't didn't engage third, and then i when let go of the clutch it stayed in second and locked the rear wheel. Could that what be what happened to you.?? 45+ years of riding bikes, I never had a trans do any thing like that... eek

If you don't wave to them'
They won't wave back to you....

These transmissions like to be shifted with some authority , if you shift lazily you will often get the results of a miss shift ....
