'99 Trophy 1200 stalls when braking hard and quickly

Triumph Trophy mailing list
Just recently I have experienced and can duplicate this problem. The engine stalls when braking very hard from any speed. I tested approximately 30, 50, and 60 mph with clutch in or in nuetral ... if I brake VERY hard and quickly, the motor stalls. I don't think it used to do this in the past, at least not that I noticed and I believe I would notice a stalled motor. The motor does restart immediately using the starter or if I am still coasting by putting it back in gear. Any ideas or suggestions of what to check?

TIA,
-Izzy

Re: '99 Trophy 1200 stalls when braking hard and quickly

Hey Izzy!
  I'm afraid that this is one of the few "personality quirks, people talk about. You didn't say what year or which engine tho, so this may be a tiny bit sketchy for now. I have a '95 BBBB, and as long as I've had it, I and many others have had exactly the same trouble. It's as simple as this. The fuel in the float bowl slams into the front of the bowl on very fast deceleration, and in essence the motor runs out of gas, and dies. Usually it'll fire right back up. I deal with it by giving myself lots of room, and time to slow down. Not much more, but a bit. I sometimes pull in the clutch a bit, at near stop, just to keep it running. Engine breaking, and all other functions are normal, even if it does die, so you'll get stopped, but there a certain shame to getting stopped, and not have it idling nicely. I think this is a "Carb-only" trouble, and the engine will fire up usually,  with the clutch out at the last moment before the stop, but it does take a little practice. I don't think electronic fuel injection has this problem. It's all a "mere bag 'o tell", as they say in Scotland. The only thing that might help is to measure the drop in the floats. That sets the amount of gas in the float bowl, and if it is set too low, it could exacerbate the problem. I hope Brother Gregory will chime in on this, as he may know something important to add..........Greg? You there?
 Kindest regards,

Hi Izzy,  Jack is right, the fuel has sloshed up to the front of the float bowl. There are no baffles in the float bowl.
 My bike will do the same thing. I try to keep the engine braking connected to the rear wheel. But it doesn't always happen in an Oh shit moment. Greg

Yes it's definitely possible the bowl levels are set low. On another note,
how tight of a fit is your battery?

Re: '99 Trophy 1200 stalls when braking hard and quickly

Triumph Trophy mailing list
Thank you to all for the responses. To be clear I am talking about extremely hard braking from speed. It did first occur in an "oh shit" moment where I was bearing down on a stopped car much too fast (for most people). I had things under control but was shocked the bike stalled so I had to do it again, and again, and ... :) BTW I have a '99 BBBB. My battery is a Big Crank that fills the battery cavity and the connections are tight. Prior to reading your responses I was thinking maybe my side stand was starting to drop down causing the ignition cut out. I do still want to check this, but I am a bit relieved hearing about the carb scenarios. I do believe I can control the situation keeping the motor alive by judicious use of the clutch. It just surprise me the first time. Thanks again for all the input. Very much appreciate it!

Locate the alarm socket on the lower side of the battery. It should have a
single wire jumper plug plugged into the socket. Figure out which two are
being jumped. Cut them loose from the socket and solider them together.
Then see if the issue still occurs.

Not suggesting as a permanent solution but how about increasing the tickover speed 100 rpm, this may give some respite and keep you alive. I would then make certain the idle mix adjustment was correct before embarking on a carb overhaul.

I wonder if there is a tip-over failsafe pendulum that shuts off the engine when the bike thinks that it detects a crash.  Other possibilities could be a wire that presses up against a surface under hard braking and shorts out.  It doesn't seem like a fuel-related problem.

My 97 900 will stall like that when I have the choke on.  I do not believe it's a starvation problem, rather a flooding problem.  It goes away the instant the choke is off.  Make positively sure that all of your carbs are actually returning the choke rod back to a fully seated position.  A little wd40 will help get them seated properly if they are not returning 100%.  

If that doesn't cure it, I would be checking the float height in all the bowls.  Probably too high.

A few minutes ago, I thought no possibility of a fuel issue, but reading other posts, now I'm thinking...
You could theoretically get the fuel to stand on the front wall of the float bowl chamber.  The main jet pickup is in the little well at the bottom of the float chamber, and the carbs are tilted forwards slightly.  If you brake hard enough to move the fuel out of the wells, then you would starve the engine.  If the clutch were in at the same time, it would stop running quickly.

Re: '99 Trophy 1200 stalls when braking hard and quickly

Triumph Trophy mailing list
In reply to this post by Triumph Trophy mailing list
I tried it again a few times yesterday ... I could NOT get it to stall
out.  I am starting to believe it is NOT fuel but electrical somewhere.
FWIW the only difference in conditions was that I was low on fuel yesterday
(guage read lt 1/4 tank), whereas when the engine did stall, I had close to
a full tank.

When I have time I am going to try and check various electrical connections
including the alarm bypass, the sidestand switch, and any other connections
I can come up with and see what I find.  Chances are I will never find the
cause and quite frankly that is ok ... I much prefer to focus on riding and
I do very much enjoy riding like a stole it!

Could it be a vacuum thing? With a fuller tank, the sloshing could "try" to
draw in some air through the cap... but can't.  Not sure I recall something
like that acting fast enough to cause stalling though.  Just throwing it
out there.

I'm pretty sure this is right - choke part on.
Long story but when I bought my 99 BBBB I found out too late the PO had
removed the choke cable but had bent the choke linkage slightly so the choke
was partially on, so it started from cold OK. Before I fixed that, the bike
3 times stalled on heavy braking - heavy enough to almost lift the rear
wheel. Having fitted a choke cable and resolved the bent linkage, the bike
has never stalled like this since.

My 97 900 will stall like that when I have the choke on. I do not believe
it's a starvation problem, rather a flooding problem. It goes away the
instant the choke is off. Make positively sure that all of your carbs are
actually returning the choke rod back to a fully seated position. A little
wd40 will help get them seated properly if they are not returning 100%.

If that doesn't cure it, I would be checking the float height in all the
bowls. Probably too high.

Choke ... eh? So this makes me wonder ... You see I recently installed a
set of Genmar 1 3/4" handlebar risers. I wonder if I may have offset the
choke cable geometry a bit such that it is partially on? I don't know how
to check this but I will see if I can figure it out.

Yep! Make sure they are all the way in when the lever is in the all the

Removing the tank and disconnecting the choke cable would allow you to ensure that it activates/deactivates correctly.  Then, you could re-attach the choke cable and ensure that it's closing the valves all the way.

Re: '99 Trophy 1200 stalls when braking hard and quickly

Triumph Trophy mailing list
In reply to this post by Triumph Trophy mailing list
Out riding yesterday ... I can definitely repeat the stall if I brake VERY
hard from as slow as 30 mph to almost stopping. Before heading out I looked
at the choke cable to see if my adding the handle bar risers appeared to
make a difference ... visually, I could not tell. There appears to be as
much slack on the cable now as there was before fitting the risers. So if
indeed the stalling is caused by the choke not being all the way off, then
it was likely that way before I added the risers. Soon as I can I will
remove the tank and inspect to see if I can tell if the choke is not fully
closing (or is it opening). It will be at least a few days before I can
make time to investigate more, but I'll report back my findings.

Thanks again for all the suggestions.

Re: '99 Trophy 1200 stalls when braking hard and quickly

On a 1200 you don't need to remove the tank to see if the choke
[enrichment] pistons are closing completely. At least the one on carb
one as it is clearly visable at the top of the carb when you move the
enrichment lever. When you pull the lever back a small piston should
exit the top of the carb and return to its previous position when
pushing the lever forward again. If that one is moving from stop to stop
it's most likely that all the others are too! At least it's a place to
start!
