Lite intressant info saxat från TY.
"-...I had a set of the CPR's for part of a season on my 2002 along with a Speedwerx head to level out the compression. (during the 2003-2004 season). I popped the motor (my fault) and went back to stock. They had awesome top end IF the temperature outside was perfect. If it was warm ,around 32 deg. F ,it ran like a pig, drank alot of fuel and could only top out our other stocker. Otherwise ,on a day like that ,the stocker gave me fits in the low end and midrange. On a cool day it was completely opposite. I guess my point is, they seemed a bit flat in the low/midrange, but came on like crazy on top end. If I were to do it over again, I would choose Bender or SLP for all around trail riding. If I wanted to race, I'd go with these pipes for sure. My buddy has a BB780 that's stretched out to 136", AD Boiven skid, 1.5" Camo, , Mega power heads, etc. w/ CPR pipes and that thing is very impressive. No dead spots there. The Viper with pipes just performs better all around with the BB kit. Go figure. From what I have heard, they tend to be more reliable too."
Dessutom står det massor att läsa om att bestyckningen är synnerligen känslig och att göra luftboxmodifieringen är riskabelt pga att den pendlar i att gå fett/magert när det skumpar mkt. De flesta avråder från luftboxmodden och att man därför tappar 3-4 hästar, men vinner i driftsäkerhet.
