A "Mild" 117

[DaFrankster]

I'm having a 117 inch motor built on the "Mild" side to keep from having to worry so much about bad fuel and running hot in the summer.

Question #1

With compression set around 9.8, will I still see HP numbers near 120 and Torque numbers around 125? Pipe dream? More like 115 HP and 120 Torque?

Question #2

Will an Andrews 54H cam with a 4 degree key produce lots of usable Torque down-low and through the mid-range? I've run a TW6H Cam with a 95" build, and that puppy was fricking noisey...trying to go with a cam that's strong on Torque and "Quiet" on my ears.

Question #3

What pipe (or pipes) can I run that produce good numbers, nice sound, and not TOO loud? I'm currently running a Road-Rage 2-1 with the "Supposed" quiet baffle. It's fricking LOUD with the 95" motor, how much louder will it be with a 117? Is there an alternative that will produce good numbers and not cause the folks on sidewalks to plug their ears as I ride by?

Trouble is, there's a pretty large-scale movement to "Ticket" loud bikes in my neighborhood. I've managed to stay under the radar with the 95" motor, I'm thinking I won't have as much luck with the bigger 117.

Thanks for your input....

See GMR's website with 117/54's. A super trapp and tuning and you'd be good to go.

Don't know why my last response was deleted, but I'll try again.

I think that's reasonable. My 103 is at 10.5:1, and I'm making 116/116. With the additional displacement, you should be able to see those numbers, even with the lower compression.

That's a common complaint with Woods cams, and the reason I chose not to use them. I'm running T-Man 625s, and they're quiet as can be.

I'm running a D&D LowCat with a quiet baffle. It sounds downright mean, but at idle and low rpms, it's reasonably civilized. I'm sure I'm leaving some peak numbers on the table, but it's more important to me not to piss off the neighbors. My opinion is that the quiet baffle will choke a 117. That said, it should also give you sick low-end torque while sacrificing top-end power.

But that's just my opinion.

There is always the Big bore quiet muffler, that will slip onto the fat cat head pipes.

Here is my 117" and I would consider this a Mild build, I built it to be reliable but yet fun and fast. 10.25-1 compression TW9 I think they are quiet. A Fat Cat which is the quiest in the group I ride with but yet the quickest. It never runs hot and no problems with any gas I run. The only thing I would have done different is balance the crank.

Low End Torque is THE BEST, I wanted it to make make peak power where I ride it not at 5000 RPM JMO.

A 117" with any of the several low lift cams that are out there, would, if fact, exceed your torque expectations.

THe hp number will vary on the t/b that is in use. Really the need for high hp when you have massive amounts of tq does not mean much.

A 9.8 compression 117 with a stock t/b, true dual pipes will make in the 110+ hp level tq 130+ . We like the 54 cam in that package and have two more going together now. No need for a + gear at all....In fact one will hit the dyno soon. This one will have a bored t/b should be intresting to see how it turns out.

The usable tq in a 117 that you have is amazing. The use of a supertrap 2-1 would drop the noise level way down. We just tuned a 117 with this pipe. I tested the bike with 20 disc closed cap, 20 open and no discs at all. End result was less than 1 full hp or tq gain either way , however the bike was extremely loud.

I am testing the D&D with the new concentric baffle but at this point I do not know who it will work with a 117. In smaller engines it works great and is very quiet, I feel on a larger engine it will rob a fair amount of power. But only time will tell on that. The QB for the fatcat does not hurt the milder 117 in any way. Has a nice tone but louder than the Supertrap.

I believe that you have a solid plan with realistic expectations. My suggestions for best torque would include the R&R stage 4 head work, the Andrews 67 cam, and Bassani Road Rage pipes. The 54 cam may work very well for this with the 1.725 roller rockers also.

[sublime]

I have seen a 117" with a Woods 6, larger injectors and a D&D Boarzilla busting 120HP and 130 ft. lbs. of torque... I imagine the 54 would perform about the same.

[HDWRENCH]

The t/b becomes the stumbling block on the big inch small cam engines, as well the smaller cams dont have the lift nor the duration to give you that huge big end power.

We did a 117 with a woods 6 45 mik and 2-2 pipes it made a bit less than the same kit with a 54 cam. So what you are seeing is that finding the middle of the road cam is important. The 54 seems to be that cam. Looking forward to the next tune here with a bored t/b .

If you keep going I feel it turns into a much bigger money deal than when you started. And the gains are in the upper rpm range only say 4500+ .. have not had any one with a mild low compression 117 complain about lack of power .

I have said this before but a 124" with R&R 615 cam and 1.725 rockers would be a killer combination.

randy, hwe wanted quiet man!

[Hillside]

Have witnessed several 55 HPI t/bodys on 117" with Wood 6 cams, set at 9.8-10.0 cr, and a D&D Fatcat POUND the torque imediately off idle, and flatline until it runs out of cam about 4700, as early as 12/06.
Rock solid combo as long as big hp is not a priority.
Makes for a fun touring bike.

Here's what I have on order, or already in hand...Starting with a 2005 FLSTN shown in my signature

1. Andrews 54 H and a 4 degree key
2. Stock Throttle-Body bored by Baisley
3. 2-1 Road Rage pipe with "Quiet" baffle (ha-ha)
4. Baisley Street-Ported-Heads
5. Roller Conversion Chain set-up (hydraulic Tensioners) with 07 pump and Latus Spring
6. S & S Crank (Sending to Darkhorse)
7. Doherty Power Pac Air Cleaner Assembly and Myst-Free
8. Stock 5 Speed Tranny
9. VPC 84 with the SE Spring (might need an upgrade here) Thoughts?

[Hillside]

Use all your existing parts, bore your cases, send Hoban your crank, convert to Timken, and get an Axtell cylinder kit. They offer a -10cc piston. That simple.
Tune it, and your done.
