FMF Q4 question

If you want more passing power on the freeway 13 tooth is great, going about 65mph your 6th gear is in the sweet spot, one good full throttle pull and you are up to 85 in no time without downshifting

You will lose top end speed with a 13t counter sprocket, but you'll gain more torque. If you do mainly street I'd stick with your stock 14 or go up to a 15. I max out at 80 mph (actual) based on my mods with a 15t.

My powercore4 was pretty noisy new not awful but not quiet. I didn't feel the powerbomb (header) affected my jetting at all. Like I said I did the slip-on first without the jets and the bike was fine I didn't check the afr at that point but it was good to go. When I opened up the intake side was when I jetted it, as you could tell it was lean with just the lid off at that point. My bike is an 09 with about 6K hard miles on it and it still runs like new (only better).

For the type of riding I do a 15t is fine. I have no problem popping the front if I want to. Where I notice it is at max speed into a head wind. The bike will only do so much.
