i have a 97 mm 600 with smart carbs. its jetted with 157.3 main i belive. stock jets are 160. it ran fine with the stock can. after i put the mbrp on, it seems to run fine for about 5 min and then looses all power and will bog all the way threw. max rpm that it will hit is 7000. i know aftermarket cans will lean it out, but it has always seemed to run on the rich side. is this can making it lean out that far?
