Static CR is just number; doesn't mean anything. Corrected or dynamic compression is what the motor sees as well as CCP. Scott knows how far to push the envelope with the 57 or any other cam to get the most out of the cam. Don't worry, you will like the 57; a nice cam for your motor.

What is the stock drive pulley the 2013 Breakout comes out with?
Primary Drive Chain, 34/46 ratio I guess that means its a 34 tooth?

I was talking about the final drive pulley. Yes,the primary i beleive is a 34/46. That can be changed also,to a 49 tooth Evo industries clutch basket. Probably a better way to go, but it isn't cheap.i opted to go for a Baker DD7 in my RK. Three options to change your gearing..........

Trans pulley is 32T. If you drop to a 30T, you will likely need a shorter belt. You can drop one and retain the OEM belt and some have said that they were able to keep the OEM belt with 30T but most run out of adjustment and need the shorter belt. You will also need a speedo recalibration with any changes to the secondary drive.

Andrews 30 tooth $120 or Baker 30 Tooth $160
139 Tooth Drive belt $ 120 - $200
Power Vision allows the adjustment of the speedo

Trans pulley will run about $100 and belt about $200, plus cost of primary fluid, gasket, etc. Labor intensive outer and inner primary must come off to replace swap the trans pulley; guessing shop rate to R/R to change pulley would be about 4 hours, so what? another $350-$400 depending on book rate. So, I am guessing $475-$525 to swap pulleys.
If belt has to be changed, rear wheel has to come off and swing arm dropped; so what? another 4 hours, plus new belt at $200. So, I am guessing another $550-$650 to swap belts.
Conservatively, say $1300-$1400 to swap pulley and belt, but that's just a guess.

Than djl, I should have been more clear. Pricy but probably a nice mod. esp. if a guy did him himself.

Can't have it both ways, stock compression will make a loopy cam a bottom end turd. Loopy cams need compression because of the larger cam overlap to perform right. Not possible to create a carbed style sound on the efi bikes so taking the advice on the stock compression cams in previous posts is the best move. Or you could drop a high overlap cam in your stock motor and have erratic crappy throttle response until about 4000 rpms, but will sound cooler at the red lights.
Should have built one like this:
Nice bike by the way ntraindavef love the sound

The link posted in his above post is to a dyno sheet showing a 103 Stage IV kit making 116HP/116TQ; total nonsense and might happen in a parallel universe but not ours.
There is the "rest of the story" missing and we will never know what it is but there is no HD Stage IV kit that will make that kind of power in a 103; not happening. Either the motor is larger than 103; the dyno is one of those "happy" dynos or the Stage IV kit has been supplemented with non kit components.Furthermore, there is not HD cam that will produce equal TQ/HP numbers; the profiles are such that it just won't happen.
As for all these many happy 103 Stage IV owners that mirrmu keeps referring to, I wonder where they are and why they aren't chiming in to support his claim of the superiority of a MoCo kit over the options available in the aftermarket.
mirrmu just doesn't know what he doesn't know but you gotta love his persistence in spreading inaccurate information.
