2003 EC250 2 stroke What top end kit to buy?

[Hotrod460]

Are the aftermarket top end kits on ebay any good? Dumb question?
Wish BBR made a kit.
What all should i replace when re-doing the too end?
How to check of reeds are good etc?.
This bike has been extremely reliable for many years! Even has a plate.
Appreciate any advice and parts sources.
What jetting is preferred and needle? I ride in WA state above sea level 500-2000?.
