Hi Joe, I've forwarded this to the list. Someone there will be glad to
offer you the correct advice, as opposed to what I might say to make matters
worse.
Listers - if you reply to the list address, make sure to include Joe's
address as well.

The tube at the top of the carberetor for excess fuel is leaking - why is
this happening and how can I stop the leak? Thanks, Joe Otto

I have a 1987 klr650 with stage 1 dynojet, k and n filter and produro
silencer. The problem is, it starts and idles ok but when i rev it over 2,500
revs approx, the carb coughs and the bike dies, hence i can't get it to ride.
I'm not a mechanic but what can i check for? cheers.

Did you install the dynojet kit?
Did you drill the slide?
Is the needle in the 3rd or 4th groove?
Are the 2 spacers fitted?
Fuel tank vent clogged?
Fuel supply OK?
Float height OK?
Vacum leak?
A few suggestions of the top of head, good luck.

Guys, I am having a real problem this week with the carburetor on
my '98 KLR. It ran just fine last Sunday on a dual sport ride and it
ran well when my son rode it to school on Monday. But when he got on
the bike to ride home, it started running very rough. I have played
with it all week: cleaned the carb body and all the internals twice;
played with the choke cable, adjustment, spring, etc; and set the
float height, all to no avail. Here are the symptoms: It starts fine
and idles fine; it runs on 3/4 to full throttle just fine; but from
about 1/8th to 1/4 throttle it acts like it is running very rich. On
a 2-stroke we would say it is "four-stroking", firing every other
time and belching lots of black smoke. I guess you would say it is 8-
stroking, firing every other power stroke. The plug was very black
and the back of the exhaust pipe is very black. If I run it up the
street WFO it runs great, but when I try to ease off the line it cuts
out, pops out the exhaust (not the air cleaner) and will hardly run.
Could the choke valve be not sealing correctly? What would cause it
to run well in the morning and mess up this badly 2 hours later? Any
thoughts or suggestions would be very welcome. Thanks.

I'm cleaning and rebuilding the CVK40 on a friends KLR.
The bike has been sitting for a long time and the crud is thick and everywhere.
The problem is I cannot remove the choke plunger from the carb body.
It has soaked in carb cleaner for hours, even tried rust remover, nothing has worked.
I will let it soak again tomorrow while at work..
Any ideas on how to get this thing out would be greatly appreciated
TIA.............

I'd soak it in Liquid Wrench if you're going to soak it. Otherwise,
I'd heat it carefully with a heavy duty soldering iron or pencil
torch.

WV,
Maybe try using a bit of compressed air from the "other side" of the
plunger. I think you could look at the bottom of the carb body with the
engine side of the carb to your left. From the right (air cleaner) to
the left (engine) side... first comes the float valve seat, then is the
main jet, just past that and slightly out of line and deep in the body is
the pilot jet. Finally you get to the starter jet. I think if you apply
air to this passage it would help remove the plunger.
If that doesn't work I'd probably try soaking the carb body in almost
boiling water for a few minutes and then try to remove the plunger.
Good luck,

+1 on the heat idea. I have freed up varnished carb slides by putting the carb in the oven
at 200F. Might work on the choke plunger, too.

I'd like to wish the other denizens of the DSN group a happy
Thanksgiving Day. Celebrated here since 1536 and still going strong.
On a slightly different note, I understand that since the financial
bailout, the Wall St executives are celebrating a happy Thanksgetting
Day, celebrated annually since 2008.
Have a good one.
