Hi all,

Been on a bat wing for a few years and then got my senses back and just got back into the tank with a 19 RGU. So far, I am impressed with the M8 and am amazed the MoCo allows us to do the upgrade and still cover them under warranty. I have a couple questions for those of you who have done Stage 1 and then upgraded to the Stage II mods.

My riding consists of true touring (rides across the country), local highway riding and probably about 10% city riding.

My questions are...

- Is the upgrade from the Stage 1 to the Stage II mod worth the additional cost over and above the Stage 1 mod? Please explain why it is better.
- If so, the SE8-447 cam looks to fit my needs much better than the SE8-498 cam. I'm not a revver. Likes/dislikes with the SE8-447cam?

Thanks in advance!!

I did the Stage 2 on my 107.....went with the torque cam, a full V&H exhaust, Harley's tuner plus the auto-tune module to keep the warranty. I love the Tq cam....pulls like a freight train until about 4 grand. Prior to this I had a 110 CVO with cams, exhaust, air cleaner and a dyno tune. The 107 runs way better than the 110 ever did. Go for it with the Tq cam.....you won't be dissapointed.

I very very rarely go above 4000 RPMs. Even with the stock 107 with stock exhaust the bike's acceleration matches up with the noise it puts out nicely.

We were sitting on a porch in the Smokies one day and watch and listened to this Harley cruiser take off. It sure sounded like he was moving but we all laughed at how slow he was accelerating!

So, if I were to go for a stage II it would be the torque cam to increase acceleration instead of top end HP. Save that cam for the dyno shootouts. LOL!

First let me say that from what the OP is describing about his riding style I would also recommend the Tq cam. It will increase responsiveness and just be a much better performer over the stock cam.

To your last statement... The Hp cam is not at all just about top peak Hp. I hesitantly installed it in my bike thinking I would just swap it out after a short while but I decided to give it a go based on recommendations from people I trusted. Plus I put the Tq cam in my Fat Bob and wanted to see if I could compare how different they perform. I was pleasantly surprised at how well I actually love the Hp cam. I do a lot of riding on the slab and like to cruise at 80mph or above. With the Fat Bob and Tq cam I thought it did a great job because it was quick off the like and so responsive to the throttle twist but when cruising at 80-85mph it seemed to run out of juice fast if I accelerated from that point if I wanted to get passed a line of semi's or get out of the traffic if there was an opening up ahead. With the Hp cam cruising at those speeds seems effortless and acceleration from there sets you back in the seat and pulls hard all the way to the speed limiter. Actually hits the speed limiter like a brick wall. The Tq cam just wasn't like that. Now as far as the riding lower in the rpm range it is no where near as bad as what people might think. No it's not the Tq cam but it is really not far behind. I would gladly ride with the most spirited rider you could find running the Tq cam and let them just try and leave me. They would be surprised.

Not explaining all of this to sell the OP on the Hp cam. Just wanted to say that the Hp cam is a great choice for many riders and is not the sluggish thing off the line some like to think and is a better choice for those that like to ride higher in the rpm range.

Thanks for sharing your experience with the HP Cam.

Question: What would the difference be between the 2 cams if you downshifted to 5th to perform that pass instead of rolling on in 6th?

The reason I ask is because every automatic vehicle I own will downshift a gear during an aggressive pass so I just reasoned that this is what I should do with a manual transmission.

Every bike I have owned has a higher top speed when running one gear down from whatever top gear is. Something about overcoming wind drag but I have never done a power mod on a bike or changed gearing except on dual sport bikes. I haven't tried to find top speed on the Road Glide. Just doesn't seem prudent. Not gonna do it.

Unlike RGKen, I haven't had the opportunity to ride a HP cam. What I do know is that the TQ cam pulls like a son of a gun on the low end RPMs, especially in 1st, 2nd and 3rd gears.

I do a lot of highway riding, so comments like RGKen's really makes me wonder if the HP cam would have been better for my riding style... I'll find out someday...

One thing I do think is that any HD stage 2 is worth the money, and the best bang-for-buck upgrade.. I did stop there though. It would have been at least another $1k to bump to a stage 3, and according to HDs own dyno charts, I would have just picked up a couple ft-lbs of torque (and it would have just bumped my 2019 from a 114 to a 117). So, at least for now, I decided to stop at Stage 2.

I did stick with all SE parts and upgrades, because I got the ESP and want to make sure that if anything hits the fan when I'm on a road trip, the nearest HD dealership will cover it under warranty. Just my 2 cents.

To me the Hp cam is better if you do downshift which I like to do anyway. When you are already going at 3k rpms and roll on the throttle the Tq cam will pick up a little better right off the bat but will level out soon after. You will continue to gain speed but at a gradually slower rate. The Hp cam just starts pulling and pulling harder from there. If you downshift from there the Tq cam will be even closer to falling off its peak power and the Hp cam will be more in its meat so I like the Hp cam better there. I can understand why people say they want a cam that they don't have to downshift on but when I am going to pass I know it ahead of time and am already timing my shift and getting the bike in it's range rpm wise to accelerate how I need it to. Downshifting really takes no time for me to do and I don't see it as an issue. All in ones riding style and what you want.

I say ride the bike this summer as-is and pay close attention to what area of the torque curve you want to improve.

There are plenty of dyno sheets flying around to compare with.

I've been very satisfied with the engine management system on my 107 and have spent money on items that will be used for touring comfort/functionality.

Be aware that a cam isn't really a magical solution to "power" by itself.
It merely changes intake and exhaust opening and closing, which changes the way your engine behaves, and effects other areas of the torque curve.

Your stock 114 has 122 FPT .......so you are covered there - Power Cam balances the motor out and gives great pull all the way through the Rs - You say Coast to Coast Riding so I am guessing loaded up and running is how you roll.....power cam all day for better hwy performance - If you have a tuner you trust, ask them to show you some pull sheets and you'll see what I mean

It doesn't really work that way when you change cams. What you had with one cam is thrown out the door when you change cams.

Maybe I'm misunderstanding what you're saying though.
