No load stall

Postby OnPapasWing » Mon Jul 14, 2014 4:48 am



Here's a question that may have been addressed already but not sure how to search this problem so I'll ask it here. Problem is that as I'm riding and coming to a stop, if I pull in the clutch, thus removing trans load on the motor, as soon as the RPMs drop too low suddenly, the bike will stall. If I goose the throttle to keep the RPMs up while bike is slowing then it doesn't stall. I don't need to keep on the throttle just a blip. Once the bike comes to the stop it will idle fine.
If I brake to slow the bike, whereby not unloading motor and only shift down while going at a slow speed I don't have the problem.
Not sure if I'm describing the problem or if it even is a problem. It maybe more of a technique issue.
I'm thinking vacuum related but, like I said, it may really be just improper technique.
Otherwise, performance is fine. '96 SE.

vacuum leak = high idle ( doesn't sound like your problem)

sudden change in RPM= stall...sounds like bad gas ( try some seafoam/gas conditioner)... with ethanol in the gas ...it absorbs water...you could just have some water sitting in the bottom of the bowls...the pilot jet circuit picks it up and the bike can combust the fuel (water)

when you "goose it" the fuel comes in the main jet circuit with enough "good fuel" to run and idle

when you come off a high speed run the fuel pump may be picking up more fuel (with water) and sending it to the carbs...when you goose it you change the ratio of fuel to (water)

try the simple fix first...hope this helps

Silly question, perhaps, but what's your idle set at? My bike was set to 700 RPM, a little low, and sometimes I heard it trying to do what you're describing. I boosted the idle to 800 RPM & the problem vanished. Just a thought...

I don't have a tach, other than what's on the bike already, obviously. But the problem with that one is that the resolution of the lines is not that accurate. I will have to try and scrounge up a tach somewhere. It could very well be that it's running a little low. Maybe I can take a picture of where it's sitting at idle and post it.
Would that just be the idle screw near the gas cap?

Yep, that's it, the knurled knob to the right of the gas cap. It's pretty sensitive, a tiny bit goes a long way. Think of it like a clock face - 1 minute=100 RPM on my bike

Perfect, thanks. I'll take a look at it.
