I'm currently running a 100/90 headlight. Wanted to upgrade. Available is
130/90. Anyone running this wattage, and any problems with heat?

Todd,
I have several concerns about the 130/90 watt bulb. The main
potential problem is the wiring harness & switches on the KLR.
There have been numerous messages about the quality & capacity
of the stock setup. If you have already run heavier guage wire
from the battery to the switches AND you are using a heavy
duty headlite relay, you might be okay, safety wise. The danger
is in trying to 'push' too much amperage thru an inadequatly
sized wire. Excess heat (in the wire) is generated in this case
and you run the risk of melting the wiring harness, causing a
fire, frying you're electrical system, etc.
If you've already upgraded your electrical system, you may have
a problem with the headlite drawing too much power for the stock
charging system. The rated output for the KLR is 14 amps
(@14 volts) at 8000 rpm. This works out to 196 watts at 500 rpm
OVER redline! At 'normal' engine speeds, the alternator's output
is less. I wouldn't wanna bump start my beast because the
battery was slowly being drawn down.
Excess heat from the headlite? I don't know if this would be a
problem. Eric J. has a link from his website to "Daniel Stern
Lighting" which has in-depth info about various headlite solutions.

Does the KLR headlamp use an H4 bulb?

You can also use a 9003 bulb. I like the Sylvania Cool
Blue, much better than the stock blub IMO. It is about
14 bucks at most auto part stores.

Fred,
What is the cost of the Mikuni carb for the KLR? I bet that is one part I
can cross to the KLX with no problem. (at least I hope so)
What are some basic differences from the CV that would make having the
Mikuni desirable?

The Mikuni performance carb kit sells for about $215 and includes the 38mm
RS carb, throttle and cable. This kit includes extra main and pilot jets,
fuel line and clamps. The instructions are pretty simple but complete.
This carb kit will make a big difference in throttle response and low speed
power. I doubt that there will be much power gained on the top end but
trail riding will be much improved with this carb over the OEM CV carb. The
reason the CV is used for a street bike over most dirt bikes is because it
makes the bike respond smoother and moderates your throttle inputs so the
bike reacts slower. Good for a street bike but bad for a dirt bike when you
need power RIGHT NOW. Vacuum operated slides just don't react fast enough
at slow speeds to open quick enough to give you much power instantly.
I don't have my catalogs in front of me now but I bet there is a different
carb kit for the KLX. There is a different carb kit for the earliest KLRs
and the late model KLRs mostly because of the different throttle cable
lengths. I would imagine the carbs are the same.
I am looking forward to Devon's dyno results. If you need this Mikuni carb
kit, let me know.

Fred,
Thanks for the response. More top end speed is not what I am looking for.
Performance would be nice but my main concern in changing would be to make
the bike more dependable. If changing to the Mikuni carb would mean my
machine required any less maintenance, I would definitely be interested.
Does the Mikuni eliminate the vacuum diaphragm?
How hard is it to get the Mikuni "dialed in" ?
Thanks for all your help.

Changing to a Mikuni carb won't mean any less maintenance but it will mean
you won't ever have to worry about a diaphram tearing or leaking again,
since the Mikuni doesn't use a diaphram. The Mikuni is easier to "dial-in"
for several reasons. First the main jet is more easily accessable. There
is a big nut on the bottom of the float bowl that lets you change the main
jet without pulling the float bowl off. Changing the needle position on the
Mikuni is much easier and the rest of the adjustments are about the same.
There is even a remote choke kit so that you don't loose your handlebar
mounted choke lever. One problem just recently brought up was a vacuum port
needed for the petcock. I don't know if that has been addressed on this
list yet. I have sold a number of these carb kits and not really sure what
others have done about this.

I have a 36mm Mikuni roundslide on my '81 SR500, basically a smaller
size of the same carb in the KLR650 WHite Bros kit. The SR500 uses a
vacuum operated fuel tap, similar to the KLR, BUT the SR switch has a
PRIME setting to bypass the vacuum-operated function. The previous owner
was using PRIME as a manual fuel switch because the Mikuni didn't have a
vacuum port.
I got the correct position for the port from the newer 36mm carb on my
other SR, then drilled and tapped a hole in the body (easy, the body is
cast from a VERY soft alloy). I threaded in a fitting for the vacuum
hose, using PC-7 epoxy as threadlocker for a permanent installation.
This whole procedure took less time than removing a KLR650 carb, so if
you remember to do it BEFORE you fit the Mikuni it doesn't add much
time.
If White Bros is selling a KLR650-specific kit, I expect the carb to
have a vacuum fitting. The kit I bought two years back for my '78 SR500
was properly equipped. It was just the older 36mm that was already on my
81 SR500 which wasn't set up.
As on the other carbs, I will be replacing the bowl screws with
stainless socket-head cap screws and lockwashers (and greasing the
threads) before I install the carb.
