03 Yz 450 ?

14 posts in this topic

whats up guys, wondering if someone can answer some questions I had about yammies. I know someone selling a 03 yz 450(don't know if it is) for parts. how do you tell between the 426 and the 450? it has a steel frame and alum. subframe. did it come with a 39mm fcr carb? heres the numbers- 5TA1 00QH21 the carb has a TPS, but no hot start. it runs but I have no info on the bike. will any of these parts fit on a 2000 WR 400? because I have a plate on that to ride the streets. don't have a digital camera or I would have taken pics. any help would be great. thanks, Dave

The Left Side of the Engine is a giveaway. The ignition cover is unique to the YZ450.

All '03's are 450's. Both the 426 and the 450 have aluminum subs, but the 426 had it painted. Wheels, handlebars, air and oil filters, and springs are about the only things that will fit your 400.

also look at where the oil level check is at the front of the bike. if it's small (dime size) and a little off to the left of the steering head it's a 450. if it right in front of the tank its a 426 and a bit larger (quarter size).
