So, I recently received and installed a ported intake from JRK5892. I gotta be honest, I'm not at all dissapointed. I'm very critical of performance mods. so with that in mind you should know that I definately noticed a difference in the way the bike idled. the volume of the air getting pulled through the aircleaner seemed to have an audible increase to it, and the throttle response was very crisp. The bike ran much better. All in all, money well spent. Highly recommended!!

 

The one thing that comes to mind is are these bench tested? Do you guys actually do these the right way or do you just start grinding and polishing?

 

What's the cost?

 

Do you always bench test heads that are ported? Trust me man. Its quality work
