Here's a thought for anyone that has ever responded to any post with RB Designs as the subject:
* If you have the time, patience, or know how, re-jetting a stock bike for YOUR altitude, riding style, fuel, air temp etc. will make it perform better than a bike that was intentionaly jetted rich from the factory for all possible situations
* If you have the time, patience, or know how, the RB mod makes the bike a better performer for all dirt bike applications (providing you can and will fine tune jetting)
* Out of a million posts from guys who have done the mod, not one suggests putting the carb back stock
I know folks are skeptical about modifying their bike, but all the facts have been documented many, many, times before. This horse is dead unless new or original information becomes available.
