Modern Carb's-Keihin PWK

[burnone]

I've been out of the sport for many years and now re-entering and looking to purchase a new bike. Steering towards an 06' YZ250.

Question for the group is regarding the modern Keihin PWK carb that are a powerjet carb with TPS.

Are these easier to setup/rejet than non TPS older carb's.

I understand all the newer 250cc two-stoke bikes have this carb setup.

Thanks in advance.
