"Choke"(enriching lever)

Does my '98 care whether I use mine for throttle lock purposes as long as I stay off the throttle - for traveling the road from the pavement to my house? I know that the Valkyrie guys advise me to not leave the enricher on to long for fear of bluing pipes & I know that the carbs lean if the throttle is used with the enricher on. With the enricher on, the engine quits if you advance the throttle,even just a little....

The enricher you mean your choke correct, doesn't that richen the mixture until warm and then you shut it off? OR until it runs well enough to start closing it off.

I can smell a Pinesol thread starting.....lol.

When was the last time you were in your carb as in to clean or adjust it?

If never or a long time, or even if the gas has gone bad......search out carb cleaning.....get ready for it....use........Pinesol!!!!

On the Valk - it opens up another path for raw fuel to be dumped in. Don't yet know about the thumper.I only use it on the KLR for about the last mile to the house - to keep it from throwing me over the handlebars when I dump the throttle so's I can pick my nose....With the Vista throttle lock(25 bucks or so), you can pick your left nostril while holding the throttle - but you have to use the lock to get to the right side!...hope that's not TOO graphic....I've been riding a LOT of years - since around 1948....

The starting enricher ("choke") on KLR carburetors, when activated, uncovers TWO orifices: One for fuel (pointy end of plunger withdrawn from hole in carb body); and one AIR PASSAGE (when the plunger is withdrawn, its larger diameter moves away from an air passage). The air and fuel now combined by the starting enricher system comprise a fuel-enriched mixture introduced to the engine through the carburetor venturi.

Since the starting enricher admits both fuel and air, the device functions as a sort of mini-carburetor.

I'll try to post an image from this website, where the starting enricher (and 'most everything else) is explained:

Here's the image; you can see the air representation (arrows descending), and the fuel indicated (entering horizontally, from the left) when the "choke" is activated, or, the enricher is open, one might say:



Using the starting enricher as an alternative throttle might do no more damage than perhaps foul somewhat the spark plug, and decrease fuel mileage.

In my experience, with a warm engine on idle (ca 1200 rpm), a mere slight opening of the enricher will kill it; YMMV.

Me too. I don't think I understand the issue. It had to happen someday.

Happened to me most inconveniently, after installing something with a handlebar bracket. Whatever it was interfered with "cable wrap," choke-wise, and . . . when turning handlebars left lock, the choke plunger was slightly withdrawn, killing the engine . . .

Kinda embarrassing, killing the engine while trying to make a U-turn in a long line of traffic . . .

Re-routed the choke cable, curing this meddlesome and potentially dangerous problem . . . was difficult for me to diagnose; thought some electrical harness short or discontinuity was shutting me down, for awhile.

Mine runs

fine the last mile home, on the gravel road. Dump the throttle all the way and advance the "choke" a bit and she slowly goes thump-thump all the way home!(don't I remember hearing something like that as a child)? (or was that Wheeee-wheeee, all the way home?).
