My bike spontaneously jumped into gear and crashed itself

[loply]

Yup

Sitting there idling, I'm standing about 6 foot away, and it spontaneously engages first gear and runs itself into a wall, falls over and cracks the screen on someones car What the f**k?

It must be

I would of exspected the bike to just crawl off the stand and fall on its side, but to damaged some1 elses car, thats just plain unlucky.

Sorry to hear about it m8

[loply]

No crash bungs or anything, the bike just "bounced" off the wall with the front tire and then fell onto a car, smashing the screen and possibly bending the front subframe a bit.

A new screen will do for a repair, I cant see any damage to the metalwork or fairings so...

I always remember watching a small child sitting on an R1 redlining the engine, and wondering if it's possible for a bike to spontaneoulsy engage from neutral... Now I know

If only my bike didn't make peak torque at idle speed, it might have just stalled

No damage to the car luckily.

Unlucky mate, that's really unfortunate. Maybe worth a post in the workshop section so you might find the cause and fix it?

At least the car wasn't damaged and the bike damage minimal.

Not really sure if that qualifies as an entry in the Spill Counter

[Teaman]

thats one for the bcf 2006 spill counter or numpty counter

utt o, if its jumps out of gear thats a big sign that the dogs are worn out/fucked in the gearbox.
usaully down to excessive engine braking to slow the bike down rather than using the brakes.

[MarJay]

[loply]

The sidestand switch was problematic in the past so I disconnected it - It used to think the bike was in gear when it wasnt, so would prevent me from running the engine on the sidestand.

I think the engine stalled anyway, but it was on choke so one quick thump at 2,000rpm was enough to send it on its way.

Was it on a hill, because to be honest, and I'm sure many will agree that bikes dont fall into gear

I'm not sugesting your a liar just investigating different scenarios

If you sit in first gear idling and just snap the clutch out it will give quite a violent jerk. Easily enough to knock it off the stand.

Was it far from the wall?

It was about 5 foot from the wall and it did definately engage in first gear, no doubt about it. It was in gear when I picked it up, and it was instantly obvious what happened.

Nobody was touching the bike, it was started about 20 seconds earlier, and it was just idling...

Obviouslly being a 660 single it vibrates a fair bit, but its never done this before.

Sounds like a sick, motorcycle relative of Herbie.

[Mister James]

In a false neutral when you started it up? Vibration could've then knocked it back into gear?

I have a XTZ 660 which uses the same engine as you and this happening has always been a worry of mine, apparently it is know to happen on these bikes.

I read a scare story or 2 about it for my bike when reading about disconnecting all the safety relays, as standard you cant even start the bike without the sidestand down and the clutch pulled in and it wont idle with the stand down either so leaving it connected would have meant holding the bike up whilst it warms up every morning I felt I had no choice but to disconnect them.

However I am now more worried than before that it will try and run away from me next time I start her up especially as when I start her my car is right in front of it.

I'd say that its probably the vibes from the long stroke that bounced it into gear, dunno if there is much that can be done about it to stop it happening again though.

[loply]

Yeah as you said I had to sit on my bike whilst it warmed up, hence why I disconnected that switch. To be honest I think the engine is so big that even if it cutout it would still have jerked the bike off the sidestand.

I think Ill just try and leave the front wheel against a wall when the bike is idling in future, so that it will just stall without falling over...

This used to happen on my Husky TE410. It turned out to be the spring and ball bearing that would normally hold the bike in neutral were in upside down... However if your bike uses the same concept the spring could be wearing out or something.

When the husky jumped in gear i was actually sat on it and it gave me whiplash! So There is deffinately enough torque there to make it roll forward even if it did stall a few meters later.

I did a little picture that may help explain what i mean.

Hi
Looks like a monster eating a cherry

Right, so there was a dimple on the gear selector rod, and a ballbearing on a spring was being pressed into it to provide some resistance?

I might have to ask the SZR mailing list about that.
