Default Confused...

Hey ,How's everyone. Just signed up with the forum., if I make a mistake don't shoot me.
I got a 07 RK. Bored out to a 103 , stainless steel springs and a 570 cams.
and it still feels like I need some more Giddy-up. . should I go 6 speed or pump the engine up ? There is to many ways to beef it up , I can't figure which way to go ...

HELP.... HUNGRY 4 MORE GIDDY-UP..

If you have an '07 RK, you already have a six speed. Try shifting up one more time.

Your '07 should already have a 6 speed...

Maybe you need a Gold Wing?

You probably have the 66 tooth rear sprocket (pulley) and many are going to the 68 tooth pulley and are happy with the results.

welcome to the forum from York Pa. There are a few threads here on the 120 vs the 124 SS that you may want to check out if you are looking for more.

I don't know, but maybe your tune is bad. Did they dyno it after the build.

570 cam? Is that a high lift cam for HP? Maybe you need a cam focused more on torque...
