Going to talk to the dealer about a 18 SG Saturday. Don't have much time to sort thru all the threads. People that have done the stage 4 what do you think about it. what kind of numbers are you making? And I'm talking about the Harley stage 4 not aftermarket. I realize aftermarket makes better numbers but this will be included in the deal. Thanks

 

Rode my buddies 117 cvo stage 4. Ran good I thought. Gets up to 100 quick. It was quite a bit faster than my stage 2 when we raced. He did stage 4 with stage 3 cam.

 

I rode my bike with the stock motor for about a month while I waited for the 114" Stage IV Kit to come in and get installed on my 17 RK, so I got to experience both motors. I am definitely glad that I installed the Kit!!! Full SE Stage IV with the SE Pro Street Tuner and RC 4.5 Slip-ons installed by the dealer as part of the purchase so it all stays on the warranty.
