My jet kit is here, but exhaust isn't. What to do?

Well, my new JD jet kit is here, but my exhaust won't be here until next week.

Do I:
A) Install the jet kit with the proper jet for the stock exhaust?
B) Install the jet kit with the jet for the new exhaust?
C) Cool my jets, and wait for the exhaust?

The temperatures are reasonable today, but looking at the forecast, probably won't stay that way. And I have some extra time today...

What would you do?

You asked, "What would you [I] do?"

Unless I really ENJOYED repeated frustration, I WOULD NOT TOUCH THE CARB 'TIL I WAS READY TO COMPLETE THE JOB.

That is, wait 'til all the add-on exhaust parts are installed, etc.

Otherwise, you must wrestle with your carburetor at least TWICE; tackle that miserable, troublesome "choke" cable connection to the carb body; drop the float bowl, etc., etc. Not to mention, removal-and-insertion of the carb into the "hoses" connecting it to the head and to the airbox; loosening/tightening/loosening the hose clamps, and so on . . .

Glutton for punishment? Do it now, and then, when you get your exhaust, do MOST of it all over again.

Also, I have LIMITED expecations for the effect of re-jetting; beyond the 22-cent mod, I think Kawasaki did a fair job, developing air/fuel mixtures for the KLR650.

The new exhaust may justify re-jetting, but . . . what are your expectations for the new exhaust?

LOUDER?

An achievable goal, certainly!

Lighter and out of the way of the rear tire as much as anything, although a wee bit more power would be a nice added benefit. I also have some rust going on on the heat shield and the midpipe of the stock exhaust.

Table,
I agree with Lonerider- wouldn't do it twice. As for results, James from JD Jetting rides a KLR and posted a bunch of test results. He is also good about responding to questions and assisting- seemingly a really nice guy.

test results & such

I'm on a similar track as LoneRider.

Just an opinion on power vs. noise on aftermarket exhausts.
They only make a difference at high rpms and don't add much
power even then. Bikers as a whole can get killer performance
just by the power to weight ratio alone compared to any car.
There are mods to defeat the EPA crap bolted on, airflow and
mixture upgrades we do Cheap or free that the stock exhaust
can easily handle.

That being said (typed), I also understand that loud pipes are
just plain fun at times. Loud bikes, from HD's, to rockets, to
thumpers can be ridden very sedately and in a non annoying
fashion when other ears are around. Being loud just for the sake
of being loud makes us all look/ sound bad. Having riders' rights
stripped away is easier to do when we give them reasons. I.E.:
No more motorcycles along the "gold coast" Lake Shore Drive in
Chicago comes to mind. The Yups are making their own noise with
lawyers.

I cored/ removed the baffle and did the standard intake increases
for an evenly matched system. It's got a little bark when I get on
the go cable but otherwise sounds stock.

That was nothing more than another angle to see this from. I don't
wish anything negative to get started here, and your choices are fine.
Please use a little common sense and go have some fun.

So nobody is going to browbeat me about killing the environment too by removing the catalytic converter? I didn't ask which exhaust was the loudest, or how to put on a megaphone muffler, I wanted to know whether you would wait to install the jet kit before or during.

The weather has gone to crap now, so I'll wait for the exhaust. In the mean time, I'll keep flying my sticker: Stock Pipes Kill People

As to power to weight ratios, the stock 08+ KLR has less power to weight than a stock base model F150 if you include a 200lb rider in the numbers.

Point taken on the power to weight ratios.
I should have said most vehicles.

My apologies.

Loud horns and paying attention save lives.

Browbeat ya? Never. Just differing opinions.
I whacked every EPA add on in the first few miles,
and plugged it all off, down to using a full flow petcock.
Nothing is vacuumm operated other than the cylinder.

A bonus for the KLR crowd is that many of us
are old cheap farts having a third or fourth childhood
and the law doesn't "pick" on us like the rocketeers
and muscle cruiser crowd. They treat us like underemployed
Goldwingers. LOL

Ride on,
CheapMark

I understand the troubles that come with the ridiculous pipes that people seem to want to put on their bikes. My second home (figuratively) is Deal's Gap where you can rarely carry on a conversation without waiting for some group of Slayers to leave the parking lot. I also have a buddy, I don't ride with much because his bike sounds like an oversized chainsaw, and I'm trying to keep from pissing off the neighbors on my regular routes.

My stock setup wasn't treated particularly nice by last seasons road salt, and both my favorite tires (T63 and MT21) keep rubbing on the inside of the muffler if I'm riding aggressively. Also the smell of catalytic converter exhaust makes me a little sick inside.

A washer or two on the exhaust bracket hanger bolt will move your muffler outboard, providing clearance for your tires.

I use an "oversize" 5.10 X 17 rear tire on my KLR250; one thick washer insured its exhaust system clearance.
