Not altogether in order:
Set your sag (with the correct spring).
Jet the carb you got.
Service your rear suspension.
Get a damper, then a dampner, then a dampener.
One piece top bar clamp.
DF3 reeds.
High(er) output light coil....not just for lights. It will improve your spark, too.
An -EG plug gapped to about .030".
Jet the carb you got.
KX forks.
Have fun!!!
