Did you zip tie clutch handle before removing slave? It sound like you need to rebleed. Try this first zip tie the clutch handle bar overnight and remove screws to oil resovoir for air to move up.

The original question was asked and answered incorrectly. Either way the original poster was concerned about spending more money on a wideband with the RB. If you take either the PC5 or the RB racing and put them on a dyno and CUSTOM tune them while spending a ton a money for a couple horsepower its not money well spent. If I remember correctly 800 bucks from Attack for the header dyno. Either way in Mohawk's case it is not because his bike is not stock. Original poster has a stock bike with a header and probably a air filter and block off plate etc nothing major. Mohawk has cams velocity stack etc. He is extrapolating every bit of power for his mods. Keep in mind dyno number will change day to day and month to month ie humidity temperature etc you cannot compare apples to oranges. If you are going to compare anything dyno runs should be on the same day with both systems.

I contacted the experts at rapid bikes

For one you cannot increase the timing on PV5 which help quite a bit on the Gen 6 two I was under the assumption per the the Rapid Bike web site that : "The Racing module’s most important benefit is, the so-called Auto-adaptive feature, that is the ability to correct automatically the injection map adjustment by reading the signal of the stock O2 sensor (lambda) while riding the bike." And I see the O2 compensating in the software. Honestly in my humble opinion I love my sixth gen track bike which has a RB racing previously a PC3 I noticed a major difference in the entire rev range with the RB nevertheless a few horsepower on top in not going to make a difference in everyday scenarios even when you use a wideband O2 which is faster and more precise.
