So, if you saw my earlier thread, I test Road a 107 bike that had the 114 stage 3 installed and thought it wasn't too bad of an upgrade. Well, I have since had the stage 3 117 kit installed on my 2017 bike and have to say that I am impressed. An all HD upgrade that actually performs!

When cruising or just riding easy, the bike feels just like it did with the stock 114, but (now that I have a couple hundred miles on it) beating it, the clutch feels like it may need some help. Super aggressive throttle and letting go of the clutch while going from 1-2 and 3-4, I had the front tire bounce/bob/lift/ect off the ground. It was around 50 degrees so, I guess it could have been the rear tire losing grip. I'm sure I'll try it again when it's a bit warmer. I really think that if the clutch needs anything, an AIM SDR will probably be enough.

Hard throttle from 2-3K felt the same as stock, but 3-5500 was greatly improved. I am really surprised how well this all HD set up works.

Street Cannons with stock head pipe: They sound really nice on the 117. In fact, I could tell a difference, in sound, between the non-CVO 114 and the CVO117. They sounded better, to me on the bigger engine, but I still liked them on the non-CVO 114. I've heard they don't sound as well on a stock 107, though. Maybe it's the cam or compression that brings these to life. I would really like to hear them with a FM headpipe.

Adjustable pushrods: now, stock my bike was a lot quieter than any twin cam that I have ever had. With the adjustable pushrods and the stage 3 parts, my top end is whisper quiet.

Below, in quotations, is the money part and my reasoning for going with the stage 3 vs the stage 4-I posted it in a different thread, but thought it needed to be here too. YMMV

"All told, the ballpark was 6K. Stage 4, adjustable pushrods, new crank and cam bolts, spacer kit, tuner, high flow exhaust (header and mufflers), labor, and dyno time. Taxes here are around 9.25, also.

I ended up going with the stage 3 for two reasons: 1. I saw no real value in the stage 4. If you're chasing numbers either set of heads would need to be reworked. The high flow exhaust limits your muffler selection. The stage 4 cam is a poor choice for my riding style. 2. The stage 4 kit needed a 2 week lead time, for ordering. The stage 3 kit was shipped and at the dealer in 2 days waiting for the bike to be dropped off.

The stage 3 cost me 42xx (with a 10 inch windsplitter, so -160'ish)"

There ya go .. nice. I too question the Hydralic clutch, I am not familiar w what you mention (AIM SDR) .. What is this you speak of?

 

Here you go.

BTW, I ran one of these on my last bike and it worked flawlessly with no slipping. It was a 2013 CVO RK with S&S HC124, Baker DD7, and the stock CVO clutch with and SDR on it.

 

Huh.. interesting, could have used this in my 2012 CVO Ultra, slipping Hydro clutch you say worked great. I assume you didn't have a hard hit like cable clutch but worked better than stock for sure?? .. I thank you for this.

 

I ran it behind a 113 that put out 122/126.

Then on the 124 (137/132 with the Dragula and 132/136 with Power Duals and S&S mufflers)

No slipping felt or seen on the dyno.

 

I have too felt the front tire lift as well as the rear tire break loose when grabbing gears. I have the same set-up, only diff I am running an aftermarket tune which certainly ads to performance.. Next week the FM 2-1-2 M8 header gets installed so I am sure to be paying attention to the clutch performance and have already inquired regarding the AIM SDR. If you order be sure you inform them its for the M8 motor, they use different bolting for clearance with the narrow primaries...

 

The Slip and Assist clutch in the 17's is weaker than the ones in the 13 through 16's.

On my 13 CVO I was able to run a stock Slip and Assist with a 121HP and 122 torque motor. Those number will make the 17 slip.

The AIM VP-SDR Performance Kit for A&S Clutch, 3 Studs Style is a very good product.

I have it in my 13 CVO King with the heaviest spring. Its not slipping at all with 138 HP and 140 Torque.

 

Im really liking what you guys are saying, other than one small detail and it is my fault for not just asking it.. Does it slip on a speed shift? down right bang 2nd and it grabs?
