I would love to hear about how it goes for you. Where did you find that bad boy?
The Shop
Servicing suspension this week ..just because I want to. Power wise, she rips. I have a set of SS forks if I can't get the 03s dialed in.
Handling? With a good front tire and sag, it works very well. I'm a vet rider who prides himself on being in moto-shape..I am going to embarras some guys on 9 k bikes. As far as starts...if you get beat to the first corner on this bike..you may want to look at taking up tennis real hard.
Nice find
The forks can be fixed...or I will put a set of SS that I have on it. It does hit hard, but I have a CR smoker that was a HOT bike that hits harder to train on! I still have my notes and set up tricks for it. Will keep you guys updated. Racing it this weekend.

We have an old '03 450 Honda and it is scary fast and a bloody handful!
Pit Row
The Yamaha was full on moto, the Honda was more for the masses.
Bike works good, new INT tries on it now. Have 49 tooth coming for the rear.
I had a top clamp for it and put my stock O7 450 bars on it. Ridding it back to back
with a 07 and a 14 it hits hard! like a 2 stroke. Pulls like hell, feels really light and with
correct sag turns good. It wants to be ridden hard! I dig the shit out of it.
I pulled 2 starts on it and did the math, beat about 70 K worth of bikes. Now that's Moto!
Question, I have a set of SS forks off a 07 YZ that I may fit on the 03? see any issues with that? Other than
uses clamps from O7 the specs look the same. I know I can work on the 03 forks and make then better, but they will
never bee as good as the SS.

You'll have to get a set of triple clamps from a SSS equipped bike. Not only are the fork tubes larger where the clamps grab them, the centerline distance from fork tube to fork tube changed on the SSS bikes. You may have to do some work to the steering stops on the lower clamp, or on the frame to make them work properly. The steel frame has a slightly different steering stop.
The steering stem lengths vary from YZ's and YZF's, but you should be able to press your original steering stem into any set of SSS clamps to make them fit the bike. I think if you stick to a 450F clamp it will have the correct length stem.
Another thing to note is that the 2007 and later four strokes as well as the 2008 and later two strokes have a more modern version of the SSS fork. The difference is in the lower tubes, especially the axle lug.
So if you have the '07 Two-Stroke forks, you have a set of the earlier fork lugs. I believe those are something like 5mm or 6mm longer tubes than the later version of SSS components. The good thing is that your 2003 brake caliper bracket should bolt right onto those early forks. If you have the later style SSS, you'll have to find a caliper bracket from a later bike. The later SSS fork axle lug has less distance between the caliper bracket bolts.
Here are some rough measurements so you can confirm what you have:
2007+ four strokes and 2008+ two strokes:
=================================
-Distance between caliper mount bolts center to center = 78mm (3.07")
2002 - 2007 YZ's and 2002 - 2006 YZ-F's (Measured my 2002 YZ250):
===========================================
-Distance between caliper mount bolts center to center = 102mm (4.02")
Thanks Man. I have a set of SS clamps off a 07 and complete front wheel unit.
I see the issue with the stop, but should not be a game changer.
I appreciate the response.

I'm betting you're going to want stiffer springs in those babies. If my memory is correct, the YZ250 smoker has a .44 fork spring rate and 4.9 spring on the shock. (I'm basing that on memory of the stock stuff for my 2010 model. I stayed with the stock rear spring and installed .47 fork springs from a 2009 YZ450F.
Thanks for the responses, I and going to try both the stockers and the SS. I have another set of 04 forks that
I get set up and do some trackside testing, I found a set of tanks that I can use that are trick of the 04s.
There is all kind of trick stuff for the 03 out there that is cheap now, this is fun, never really been into the
high $ parts but for what I can do for the price I will have some bling.
I will do the carb mod, she is a little to easy to flame out, but she hits like Tyson in 88 and pulls hard.
Again, Thanks for the feedback.
