I'm all over the 117 this bikes a keeper😄

[Yellow09SERG]

Now that the 117 kit has been around for a bit has any of the builders looked at the length of the spigots compared to the 120 cyls to see if there is the possibility of using these with the 4 5/8 crank?

[HD Street Performance]

No the cylinders are too short, I would not do it.

[Snakepit]

For those that have done the kit...Is the engine mechanically any noisier in valve train or otherwise? Also would you be throwing your extended warrant out the window?

[RoadDawg]

Not sure about the noise. Maybe a tad more. Warranty should be good if you go with the street tuner, but check with your dealer to be sure.

The kit done by a dealer should be warrantied.  If done on a new bike the MoCo warranties it.  It also should not be any noisier than stock.

Now if your doing your own build with different parts than the kit, i'm sure there is no warranty.  It could also be noisier than stock depending on the cam choice.

Yesterday, the wife and I along a good friend did a group ride with some folks for a benefit. All in all we did 400 miles.

I was very stoked to see that I was getting 44 miles per gallon/265 miles per tank!!

It's amazing how good gas milage can be if you ride like "Driving Miss Dailsy" and not heavy on right hand!

What kind of exhaust is everyone running with the 117 kit? I realize the Fat Cat is the best, but I would like to stick with a dual muffler setup with the 117. I already have the Fullsac head pipe. I would like to have best performance possible without it being overbearing loud. Also, I am already running the 24D cam. Is the 259 cam that comes with the kit a better option or leave the 24D in tact? This will be going in the 2015 CVORG.

Jason, you can just buy the cylinders and pistons only and use whatever cam you'd prefer.  If you are already running the Fullsac DX, I assume you are also running their cores in your stock cans.  If so, what size baffle are you using?  May need to just orders larger baffles.

Multiple cams appear to work well with the kit, but compression will likely need to be bumped from what you are running today

I'm running the Fullsac DX head pipe on my 15 SERGU with my version of the 117.  I have the 2.25 fullsac cores, making 140 torque with a nice flat curve, and 138 HP

Dave, what all does "your version" of the 117 consist of besides just the jug and piston change? Did you have head work done? Your numbers are fantastic! Does it run well on 91 octane fuel?

I'll go with a solid "yes" regarding the noise due to the 259 cam.

[Dan_Lockwood]

Just an off the wall question.

Over the years of motoring, I've heard that smaller carbs on bigger cube motors tend to increase torque.  That is a generalized statement without any specifics to go with it.

So what if... I did the 117" jugs/pistons, but kept my 255 cam and the 50mm TB?  Would this just have a lot more grunt on the lower end with maybe just a bit more overall on the top end?

As I said, I was just wondering about it and how well it would work.

Any observations or thoughts would be greatly appreciated.

Thanks and have a great week to all...

Interesting question.  Watching for answers.

  I used the HD cylinders, then had CP make pistons with a 10cc dome, for an 11.4 compression ratio.  I am using the HPI 55mm throttle body I used on the last build rather than the 58 the kit uses.  I am using woods TW-9B-6 cam.  Don of HD street performance did my heads. 

The cam is a bit noisy but not as bad as I was expecting.  Woods are know for having noisy cams due to the aggressive ramp.  It really not bad in my opinion, and well worth the power.

I have not tried 91 octane.  It runs great on 93.  I may find out in two weeks on the 91, as I'm going to Bikes Blues and BBQ on this bike in North west AR and 93 is not always available.

I'll go with a solid "yes" regarding the noise due to the 259 cam.

When I built my king the first time it was with the 259 E and head work and 10.8 pistons.  I did not notice more noise than the stock 255 cam.
