Hello all


I am doing a kx500 engine swap out and I am looking for my kx500 motor.  What is the differences from a 2003 to a 2004.

Thanks you

Hello and welcome to the forum lordofhurley.
There is little difference between 89-04.
Some stator/flywheel changes in the early 90's but can run any year of stator/flywheel as long as the stator/flywheel match.
The 93 and older engines used a smaller spline on the end of the shift shaft, and a smaller spline on the shift lever to match. But there again you can run the newer or older shaft as long as you use the matching lever.
Other then that, they are the same from 89-04

I think the last half significant changes to the motor was the stator in about 92.
Between 03 and 04 its just possible that they changed the stickers on the shroud?

a true testament of how good these bikes are. they withstood the years unchanged, perfection!!!!
just like the old VW beetle, only time will tell how good a machine really is...
sorry, I'm a VW guy ( manx buggy) as well as a KX 500 rider, go figure???

Another way to look at it...I just replaced the ENTIRE bottom end of my 95, minus the flywheel/stator plate and engine cases. When I ordered everything, I just used the 04 to get all my part#'s/parts.

I always do the same. Unless I'm looking for older parts like the older kips arm I run.

Older KIPS arm you say?  What's the difference and what year bike is it off?
How is it more suited to your needs?

Just wondering like...

there's a thread that shows the arm he's talking about...if I get time I'll try to find it and post it....if I remember correctly, it's in the Jeff Ward Motor Round 2 thread.
