diaphram?

My 96 klr started acting up last summer. On a hard excelleration from full stop rpms going
up and bike lost power. It would run under 20mph I had to choke it to ride it home at
40mph. I though jets plugged I rejeted carb and it seemed ok. Running rough this fall had
valves adjusted tech looked at carb and said it looked ok. This week same thing accelerated
and bike lost power had to run on choke to get home. I saw a reference in this list to a
diaphram problem any other input. It has also happened one other time and bike
mysteriously got better overnight. Now the bike seems to be running ok but don't want to
take it far until I can right the problem. I have limited skills and this doesn't seem to happen
when I am near a bike shop. Brian A

Maybe carb ice?
Was it humid and freezing +/- about 5F?
If so, that's my guess.

Brian, I experienced the poor running at the end of last season, and
it was the diaphram, but it was not intermittent. If you do find that
it is the diaphram, be sure to go to the" Charlie- David's son" dealer
to get the carb parts. Mine was the same carb used on the big v-twin,
and the part cost less than half of what Kawasaki wanted.

Brian,
A couple of other things to check, besides what others have suggested:
1. If the bike has an aftermarket fuel filter installed, it might be plugged.
2.
If the bike has a vacuum actuated fuel petcock, it may be faulty. You
can check it by disconnecting the lines to it, connecting a piece of
tubing to the vacuum port and use a MityVac or your mouth to determine
whether the port will hold a vacuum once it is applied. Of course,
fuel should flow while the vacuum is applied.

Mike,
I don't know if this is according to the Hoyle--but,
you can check the fuel flow/petcock diaphragm for operation by
draining the bowl, and then leaving the drain/screw out for a moment.
then,
Crank the bike.
When I was draining my fuel bowl due to the contaminated fuel in
Midland, SD last summer--I cranked the bike with the bowl drain plug
removed to see if it was pumping fuel.
because,
If the petcock diaphragm is intact, every time the piston draws a
vaccum, you will get a squirt of fuel. It will look like an
aortic 'bleeder'--SQUIRT-SQUIRT-SQUIRT with every revolution of the
piston. Pretty neat, actually. Might be something someone else has
seen, but I didn't remember anyone ever saying that is how they could
check the integrity of their petcock diaphragm.
What did I learn?
DON'T have your face to close, cause if it is all working as it
should, =according to Hoyle, you will see fuel come out like it was
on a fuel pump. Eliminated all doubt if the petcock was working
correctly....
revmaaatin. who prefers water to fuel for bathing...ah, and so will
you.

It's even easier just to pull the fuel line off the petcock and crank.
