Thanks guys! I really like the way this one turned out, and it runs even
better than it looks.

I still sure wish you would reconsider using it and keep it in your private collection of 100 point perfection.
No more dust collectors! Actually, I have just about eveything needed
to make the bike showroom. But first, I'm going to race the you-know-
what out of it

what year can I take a white air box from that will fit mine?
92 to 94 CR250 or 500

1992 cr250 and do something similar
Look forward to seeing the results

Why did you choose the Pro Circuit pipe and silencer over stock/FMF/alternative?
After years of trying just about every combo out there, I like the PC or
Bills Pipe the best for "built" HPP valve 250s.

Why did you choose the V-Force 3 reed valve over a Boyesen/stock setup?
Same as above, the Vforce works best to compliment my engine work and
riding style. I like the Rad Valve for 125s but not 250 or 500s.
Quote:
interested in how it compares to newer machines you've ridden recently.
This 93 compares very favorably with any subsequent CR and is better
than most. Plusses: The motor is as stout as the baddest CR motors I
ever had. The handling is better than any CR I owned since. The bike
is lighter, more forgiving and better balanced than any gen 1,2 or 3 CR.
The minuses: The suspension is pretty good but not as good as the
stuff on the 02 and later bikes. The brakes are not as powerful as the
bigger rotor models on later models (but there will be less fade in the rear
of the 93 because of the larger caliper). The bike is not as slim in the middle
as an 02 and later CR and finally the razor sharp handling also comes with
headshake.

The only minus I can't easily fix is the bulkiness in the middle. I will tell
you, this bike is a hoot to ride and hauls @$$. Best build decision I ever
made.

I want one of those steel CR250s so bad.

Can you share what kind of special engine work you did to it? You refer to it as "built"... and I dont normally associate that with bolt ons, so I presume there's some trick stuff on the inside too.

Ok, something was wrong when I looked because the full bike pics didn't show up... Odd.

Sorry about that. VERY nice looking ride.

I would love to hear that thing run. IMOP, their is no sound that sounds quite as good as a finely tuned 2-stroke.

Be happy to. On the bottom, the crank was balanced by Crankworks,
the cases were surfaced to ensure a good seal, the tranny gears and
shifter assemblies were slick coated to reduce friction and heat, and a
Hinson clutch outer, inner and pressure plate along with akadised friction
disc were installed, a Boyesen water pump impeller along with Redline water
wetter and a high pressure radiator cap. Up top, the cylinder (a '96) was
ported by Pro Circuit, the head (also a '96) was milled, indexed and reshaped
also by Pro Circuit, VForce 3 reed, Keihin 38mm quad vent air striker carb
and a Pro Circuit pipe and silencer complete the package. This combination
is usually good for around 50 hp with a nice (easy to tune) broad powerband.

Due to the jump in compression and to ensure repeatability, I have to run
race gas, VP C-12 in this case. I used Kawasaki break in oil for the first
hour and switched to Redline at 32:1 from here on out.

I've had engines that produce more peak hp (my 2000 and 2001 were
supposed to be in the 54-55 hp range) but they were both more temper-
mental and harder to tune to conditions.

I just ordered the first parts to start building a killer CR500 engine. I will
use pretty much the same "recipe" as above to build it.

I'm working on that. Currently, I am without any kind of video or audio
recording device. I keep dumping so much money into these builds, there
is very little left in my MX budget. I want to buy one of those small video
cameras that can be mounted on your helmet. Once I get one, I will take
the bike out and tape some laps.

I started the project last Summer.

I just bought a MD80 sports camera off ebay for $14.50 shipped. You can check out videos those things have made on youtube, I was pretty impressed. There's tons of them on ebay and they sell for really cheap.


Not bad for $15...

Dogger, I am very excited to see the workings of the CR500 build. Are you scratch building the motor from OEM parts, such as buying everything or are you rebuilding a existing 500 motor? Which year motor are you choosing?

Also, what is Kawasaki break in oil? Im not sure if I have ever seen it. What does it do?

Thanks for all of the info on these rebuilds, sorry about all of the questions!
-Derek

Dogger, I found a set of forks I forgot I had. Forty three mm showas from the 93 frame I have. Forgot all about them earlier, actually thought I gave them away to a friend who has a cr500. Don't know that I was thinking.
