Where can I find a big bore kit for a 87 250x? Will the 300ex kits interchange?
Thanks guys

Would this kit work on my 250x?

Looks like the link is gone. Look around on the internet, they are out there. The 300ex kit will work with the 250x. If your keeping the stock stroke of the 250x you will only be at 288cc's. However this gives you an increased bore stroke ratio, and a nice snappy motor. If your not running the higher stroke, get the Sparks CDI box. 1000 more revs.

Check out Powroll.com

They have a kit, but it requires someone to do the machine work.
