Air filter

[Dead Eye]

Many on here (including myself previously) have an aftermarket exhaust and the K&N filter and haven't needed to re-jet. That's not to say that marginally better performance couldn't be coaxed out through jetting and dyno runs, but realistically that's possibly going a bit far...

The my bike ran fine (better than standard imo) with the aftermarket exhaust and K&N

iam with you deadeye......re-jetting with the two improvements will make a difference but will run fine with standard jets........dyno will get it spot on but good results can be achieved at home if you have the time
