RB-Designs carb mod or PowerNow?

[AZRickD]

Bike: 2005 DE 250 (12 oz FWW), LTR carb kit and LTR PV extender, FMF pipe and silencer

This summer I'm going to do a top end R&R and send the head to RB-Designs for a squish mod. I'm also considering sending in the carb (even though I have PowerNow on both sides).

I asked Ron that given my PowerNow, would it be worthwhile to ditch them and go with his mods. He kinda blanched at me ditching $100 worth of P-Now (even though the former owner bought it). I feel that the PNow in front makes the throat smaller and the PNow in back is kind of a slop-fest.

Any thoughts on the RB stuff squish and carb ?

Thanks,

Rick
