carb diaphragm question

See message 151210 for the gory detail but basically the mechanic pinched
the edge of the diaphragm (had it sticking out of the edge of the carb on
the right side rather than seated in the groove).
Previously I just lifted the carb cap 1/2" and seated it but since I had the
bike apart again I thought I'd check it thoroughly because of the lean spot.
There are 2 tears in the edge where it was sticking out. One worse than the
other. But both in the very outer portion that normally seats in the groove.

Question is are these serious enough to require replacement of the diaphragm.
I tend to think NOT, as it's just torn in the portion which sits in the groove
of the carb body. Anyone disagree.
If it needs replacing I'm gonna be tempted to go tear some mechanic ass, but
last time I called him, he didn't seem remotely interested.

They look fine to me. If you do replace it there is a Harly part # that is
about half the price of the KLR part # . It's in the FAQ

If it were mine I would not replace it, both tears are in the area
that seal and I've seen worse that still worked ok

Tony,
If that was on my bike I'd be replacing it. The tears might not affect
anything but then again they might. Since it's your money you'll have to
decide how much it's worth to not wonder about whether they are causing
you problems. : )
If I was replacing it I'd first try the Harley part from the 883 engine.
Best,

Jeff, somehow I figured you'd be on the replace it side of the fence
If I replace it, I'm gonna feel obliged to stand up for myself and go stick it
in the mechanics face ... and I really don't feel particularly confrontational
right now. Sick of the whole thing.
Wondering if some form of rubber cement might prevent it spreading further.
If the damage was further in I'd say no way, but where it's located, it's
possible.

Yup there is shade tree fix, Tony. It's worked for me for about 4 years.
The diaphragm and slide for a klr are only sold as a unit and cost over
$ 150. I'm told Harley sells the diaphragm separately but I couldn't find
the Harley part locally. I was in a hurry as I was on the eve of a trip to
Mexico. Planned on finding it when I got back but since the fix has worked
so well I haven't bothered. In case anyone is interested: The diaphragm had
a small tear at the bottom near were it fits over the rim of the slide. I
think I tore it by letting it fold over on itself when re-installing the
cover after inspecting the carb. A friend was helping me ( some of you know
Rex ). He got on his computer and wrote to the lists he was on and accessed
the various archives Someone ( wish I could give him credit, not a klr
lister ) posted a fix that sounded good; He described a specific Napa
product and he advised spraying the entire diaphragm. I used the product but
I did something different. I went to Napa and bought the recommended Plastic
Dip #756-2527. I removed the diaphragm and slide from the carb still
attached in one piece and left them that way. I cleaned the diaphragm with
some alcohol. I sprayed some of the Dip into its cap. I then took a flat
toothpick and with that handy tool applied it to the tear. I let it dry for
about 1/2 hour and repeated the procedure. I let it cure for 4 hours and
installed it onto the carb. Putting the carb cap back on is the tricky
part of the job; take your time, be careful and use common sense.
The carb has worked well for 23k miles. I don't know if it will work on your
wife's diaphragm.

FYI It's 7652527 (you swapped 56 and no -)
I was thinking whether something simple like rubber cement would work, the
kind of stuff you use to patch a tube -- as I already have some of that.
Never having seen the NAPA stuff, I guess it's what you use to put a rubber
coating onto tool handles etc, not sure whether it would work better.

Tony,
I tried rubber cement on a 4 wheeler I have. It worked for a couple
of
months, but the fuel fumes dissolved it. I ended up replacing the
slide/diaphragm on it. I wasn't lucky enough to find a Harley part
that
would interchange and had to pay RonAyers price on the replacement.

Sorry about that. Thanks for the correction. I like rubber cement but not
for this application. I'd be afraid that, without something on top of it,
the rubber cement would come off - but who knows. I do know that the Napa
stuff worked for me.

Carb. Diaphragm Repair link:

Although I'm no artist, I have a selection of palette knives that I
use for all sorts of larger spreading tasks(glues, sealers, fillers,
etc.), and they are time savers and give great results. I still use
toothpicks, cotton swab shafts, and small dowels for the small jobs.
