Project Clapped out 1998 KX250... what works?
umberto:
It looks like it has aftermarket clamps too and at least one excel rim. Somebody must have loved it at one time. Do you guys know much about the bike?
sandblaster:
Jason bought the bike from me 17 years ago?
He used it for racing and went Expert on it.
But time went on and it became a back up bike...
Then it became a bike for friends to ride.
Then it sat for the last 5 years or so buried deep in the stack of bikes Jason owns.
The amazing thing is that it started up after the second kick...
Jason does own another 98 KX250 that is pristine but that is not what this build is about.
For me, it will be a bit of exploration...
For Jason, he will have a nice engine when it's done :-D
And some of us will learn new things 8-)

any chance you want to part ways with the rear shock ? I got a spare I could trade + cash your way. if there is anything you want to know about this bike I pretty much know everything I have built 2 1997 / 1998 now within the last year.
such as the LHS sub exhaust valve that is now obsolete..... wears out on the alloy teeth but if it has the 1998 cylinder you can use the 1999 power valve with a slightly different part number that is still available and all measurements are exactly the same. I have the part numbers stashed away on my phone somewhere so let me know if you need them.
also I have a complete bike broken down for parts if you get stuck for anything at all.

This bike belongs to Jason Tanner from JT Engine Works and I can assure you that there is no way he will part with anything from this bike except maybe the seat :-D

Sweet. If you see anything that you would like to contribute, please feel free to post away.
I'm always interested in other helpful opinions.

I appreciate your willingness to get the numbers but I have all the parts numbers stashed away here:

I'm pretty flush on parts for the project but if something comes up I will hit you up.
Thanks again for your willingness to chip in.
That's what makes these forums work 8-)

The bike started on the second kick..
Amazing that it sat for 5 years in such rough condition and started right up..
After the clean up and start up, Jason decided that he wanted to use a different wheel and tire for the build...
I guess he was concerned about the extra weight..
After installing the tire he discovered that the bearings were junk.
I just happened to have some new mid 90's Yamaha YZ bearings which fit perfectly..
But, he will have to re-use his seals because the YZ seals are a larger diameter then the Kawi seals..
Just for grins I looked up the Rear Wheel HP for the 2018 KTM 250 SX and thought it was a blistering 37.8 hp.
BUt then I saw that it was for the 4T... :-(
