How have you?????

[guest40]

Ever had to stop a bike (TS250 Suzuki) with a jammed open throttle?   Scenario.....At engine melting revs the ign switch may not turn it off! The carbon in the chamber can act like a glo plug...and no kill switch.
 Just how would you get it to stop before doing any damage to the bike or yourself? Or tell us about your escapade with a jammed wide open throttle

[guest295]

Modernish bikes have kill switches, which are very handy when the throttle jams. But the only time that happened to me I had to use the ignition switch, which is kind of clumsy, especially since I had a long way to go.

It happened to me a couple of times on a friends YB100. Had to turn the key to shut it up, get off and find a small rock to twat the carb with, quick change of underwear then it was good to go.

My first bike a DT175 (twin shock) used to rev-up on its own. My father wouldnt belive me and took it for a run. He came to a halt and it was revving its nuts off, the follwing sequence of events occurred

- Ignition turned off, bikes carries on revving
- Kill switch used, bike carries on revving
- Plug cap pulled off, bike carries on revving,

At this point my father and his mate who 'new' about bikes were totally baffled and there faces were a picture. If it were not for the fact that my first bike was destroying itself in front of me it would have been funny.
 Eventually they put the wheel up against a wall, banged it in gear and let the clutch out slowly dragging the engine to a halt.

Seems the oil seals on the crank were leaking and pulling in air, meaning it was running very weak and hot enough to turn the plug into a glow plug.
Once fixed it was fine, but everytime I missed a gear I had a brief moment of panic when I thought it was going to go nuts again.

The scene

Late winter, Plymouth, raining, lat at night.  I wander out of KEmpo class, shoulder rucksack and climb aboard Triton

Ignition on, fuel on Tickle carbs, couple of kicks and we are off rolling thunder.

Dartmoor, cold, nay freezing.  Tuck in and gun the beaut.

"The Bends" roll through them on the throttle, lovely, but chilly.

Tavistock comes and goes - even colder, out towards Gunnislake, drop down the hill to the hard left - throttle feels sluggish, no worries, up over the top and down towards the Tamar - only the last few bends through the woods to go, Close throttle, close throttle CLOSE TROTTLE!!!!!!!!! Arrrrrrrggggggggg

Brakes, can move my hand no brakes good throttle, downhill to sharp bends.....


Ahhhhhhh the FB frame is better than I but jeezs I did not know it would go over that far, round the bends that fast, and thanks to the trees no ice.

Stop it down through the gears (up actually up for down) and run it into the wall of the garden in neutral to stop.  Call for help..

Gloves frozen to bars, water (remember the rain) frozen in throttle cables...

Phew

Love that Triton

Hate those cables.

Mind if the brakes had worked, I would probably have dumped it - out of line front wheel, single disk etc

Quite correct, a hot enough engine with carbon deposits can carry on running.  Air leaks can ruin your day.

1.  Whip off spark plug/use killswitch
2.  Turn off fuel
3.  Shut off air supply - easier on some than others
4.  In gear against a wall, if your brakes are carp
5.  Get off and walk away like its normal.

Yep, across the grass at Brands Hatch on the XBR with the Amal carb jammed at full throttle. Kill switch was on the wrong end of the clip on because it wouldn't fit on next to the throttle.  I didn't want to take my hand off the bar as it was a getting a bit 'flappy' on the grass, eventually I just had to pull the clutch in to slow down - by jove that bike makes a noise flat out no load.
I now have the kill switch from a TL125, fits nicely on the clutch lever mounting bracket.

no wonder you couldn't stop it  ........using fish for brake pads ...well I never :-)

[Richard]

Fish brakes.  Never thought of it before, but it has got to be better than ATE 'floating caliper' brakes from the 70's.  What fish would be best ?

I cod tope for an improvement to make it stop in its plaice.

Sorry.

Sounds a bit fishy to me . Try Brembo gold fish calipers to avoid skating on the approach to bends .

First "big" bike, gs500e, in traffic on the way home from buying it in town I get a gap and wind the throttle back WHOOO FAST (to me at the time) close throttle, crap frayed throttle cable declines CLOSE THROTTLE OHFUGGITFUGGITFUGGITTHATCARSCLOSE clutch in brake hard switch off at ignition.
Proceed back to bike shop to advise them they are fitting a serviceable cable right here right now and for free and be glad my grieving parents aren't sueing them out of business... I must've been convincing 'cause they gave in immediately 

If ignition/killswitch doesn't work then get clutch in, get control and then use the brakes/nearby object to stall the bu**er. 10 times out of 10 I'd pull the clutch and let the engine go before chancing a crash. Repairing engines is more reliable and less painful than trying to repair bodies!
(and a surprising percentage of the time an engine will survive a short spell of uncontrolled revs, I just wouldn't make a habit of it!  )

Sorry.

I've heard Great Whites have  good bite...

Oh I forgot to mention the three Atlas clutch springs in there to stop the Umph clutch slipping - worked but jeeeeez pulling in the clutch for more than 3 nS was a non starter..

Damn I loved that bike

In my youth i used to ride secont half speedway and after a spill that had snapped my clutch cable I decided it was easier to start the bike with a push and ride back to the pits than to lift the rear wheel. So we pushed, the wheel skidded and I jumped on, it fired up only to have the throttle stick flat out with me still sitting sideways. Front wheel in the air and straight into the boards Mouth split open and frame diamond bent.
Lesson learnt

My SRX has an outstanding problem (amongst others that make it SORN) and that is the CV carb flips itself open all by itself as I think the rubber diaphragm is knackered and hard and wants to be 'up'. Pootling through traffic on a closed throttle I suddenly found myself accelerating rapidly towards the red traffic lights. This is what the kill switch is for, and boy I was glad the bike has one!!! The rest of the journey home was rather interesting as I had to use the kill switch several times.

My CG125 that I learnt on a quarter of a century ago (ouch  ), destroyed its ignition switch. I had stopped after a nice journey and switched off, but the bike stayed running! Unsure of what to do I left it and after a couple of minutes I figure the vibration reconnected the dodgy wiring as it then stopped running. This was a repeatable feature and I then had to learn how to stall it to stop it for a few days. Quite bizarre as you spend all your time as a learner trying not to stall    My pops fixed it by swapping the wires in the switch so it would switch off the engine, but all the other electrics were always on (horn, indicators etc)!!
