Do you happen to have a sound clip of the exhaust? I had a streetslayer slip on and i damaged it.. (long story) now looking for another exhaust and I think I might as well go full...
I'd get it dyno tuned simply to squeeze out every bit of power out of the bike as possible. Sure, I can get the Bazzaz to give the correct amount of gas that I tell it to, but how do I know if that's the most efficient AFR the bike? 4krpm at 40% throttle might need 12.6 AFR, where 8krpm at 70% AFR might need 12.9 AFR. I don't know. It's a guessing game, cause I don't know what kind of power its putting out. You can't go off "feel." For all I know, my bike's power curve could be taking a nose dive. A dyno tune is the only way to get the power curve correct, most efficient, strongest, etc...2 questions
1) Which Arrow header are you referring to cause the one for your bike has been out for years, same one as the 09
2) Why would you get a dyno tune if you already have a Z-AFM? It will only give you some arbitrary number unless you have a base run when it was stock.
To the OP good job, interested to hear how you make out.
