XR600 Stock HP?
--SINGLE BUT SANE--
makes? what's the difference between it, and an xr400? one last thing, how
'bout an xr650l too? i know it has 50cc more, but i think the engine is a
bit milder than an xr600's.

The 650 is street oriented, I think, so is a big pig like other street
oriented bikes.
The XR600 makes "lots" of power. It varies depending on whether you
live in the USA or not. Those of us lucky enough to not live in the
USA get models with much more horsepower.
If you're ever curious, you can hit the Japanese websites which often
show HP and torque specs. The US sites almost never do this because the
numbers are lame in comparison, I figure ;-).
Honda's site is english-impaired though, and doesn't show specs
for the XR600 and XR400. So, this answers nothing, I know, sorry :-).

Whoaaaa, wait a minute here. I can believe this for street legal

XR-600 is going to have the same power as the US model (California
doesn't count :-)

Yeah, I agree Jeff. I've never seen or heard of any non U.S. spec's or
parts or the XR's.
As for the street bike stuff, I thought I heard one time that anything over
750 cc's was a U.S. market only bike because they were illegal overseas. I
dunno...just something I thought I heard one time.

Seems to me that Dirt Bike did a dyno shoot out on aftermarket pipes for the
six-honey.
I believe the stock engine (restrictors and baffles in place) was in the
high 30's and a "tuned" engine with a free flowing exhaust was in the mid
40's.
Basically the same numbers as a good 250 MX'er...but the dyno don't live in
the woods!!!

Not sure but I think some countries have a horsepower (100?) limit. They
probably still sell detuned superbikes.

I reasonably sure there is some kind of law or regulation in place, but my
point being I can't imagine why we'd get "detuned" dirt bikes (Calif
excluded of course) and full tilt street bikes...then again.....

I think it's around 30-35 HP stock.

The a dirtrider mag it says the xr400 puts out 34 horses with the baffle
removed.

Not so, Dyno breath.
A good XL-600/650, of which I am an owner, will show around 35-40
horsepower. MAX. Yes, you can get more.
My Yamaha SR-500 (single-cylinder 4-stroke street bike) will produce about
28 HP.
Horsepower is real. It can be measured. "1 HP" has a real definition in
kilowatt/hours of electricity that can be produced.
I figure a good Yamaha YZ-400 Thumper can show about 40-45 HP, with usable
bottom-end and a good overrun on top.

My shop manual says 27hp US version, 33hp Canadian. The fuel and
exhaust systems are different on the bikes.
Notable: the USA version has a spark arrestor, which is legally required
for some riding conditions, and this is not present on the Canadian
model. There are other things that are different...

OK, I can understand the spark arrestor issue, but what's different with the
fuel systems? Jetting? Bigger carb?

Wrong. I have been riding XL's/XR's for many years and from
my experience in XR/XL rentals in Greece I have found that the European
models are _WAY_ faster than U.S.. Someone told me it is because the
compression ratio is higher on the Euro models. I don't know what it is but
the difference can be definately noticed, there is no mistake. It is noticed
immediately SEAT-OF- PANTS. My most recent experience was on an NX 250 which
has the same engine as XR/XL 250 , I understand it has slightly different
gearing but the bike felt like a 600!.

reports from their very accurate Kerker Dyno, they pussied out of the Dyno
reports for some unknown reason, ( that's why I switched to Dirt Bike Mag.)
I remember that the 1985 XR 600R was producing 35.8 Horsepower according to
the Kerker Dyno, on other dynos it varies and usually higher than that
figure, more like 45 H.P. but the Kerker was/is renowned for it's accuracy.

I thought the NX250 motor was quite a bit different than the XR motor, water
cooled, counter-balancers, a bunch of things...

Yup.
: The NX250 I rode was air cooled.
Hmm. Did someone pull a fast one on ya by sliding an XR500 engine into
that NX250 frame? :-)
Good ridin' to ya,

My memory is too fuzzy on this. It has something to do with how the
crankcase vapors are routed back into the intake. If you get a breather
kit from Stroker, you can get a half-a-pony back. This isn't necessary
on the international versions...
The carb is the same. I know mine arrived jetted very rich. I don't
know how they arrive in the USA.
The US version also has a removable baffle, and the Canadian version
doesn't have this. Not sure what noise restrictions are on the two
models either. There's a chance that the airboxes could be much
different too, Stroker recommends a KX500 air filter. Looking at
what I have, I don't see that anything is going to be a huge improvement.
Then again, I could be wrong.
That's pretty much the extent of my knowledge on this.

My crankcase vent tube (on both XR's) is routed up beside the carb and on
top of the airbox...it does not recirculate at all. It would seem to me
that if it were routed into the airbox somehow it would just tend to try to
vaccuum the oil into the carb. Not a good thing?

>know how they arrive in the USA.
I don't remember what the stock jetting was, but I could go look if anyone
cares. When I installed the Yoshimura pipe and the K&N filter I went to a
168 main and a 68 pilot, with the stock needle moved one postition lower.
Works like a charm!!!
>There's a chance that the airboxes could be much different too,
Man, I don't see how, the blasted thing just does fit now! How they could
change anything other than the size of the fresh air intake is beyond me.
> Stroker recommends a KX500 air filter.
No kidding? Over an aftermarket replacement elelment? Wonder why?
> Looking at what I have, I don't see that anything is going to be a huge

>Then again, I could be wrong.
I agree, which is why I was curious about the different hp numbers. I know
that the simple mods I've made to mine made a HUGE improvement in seat of
the pants
type tests, the bike just feels crisper and has more snap to it.
>That's pretty much the extent of my knowledge on this.
Well I do appreciate you participating in what has been for me a very
interesting thread. Thanks!!!
