New 2018 Heritage Classic 114 FLHCS

[DiverRay]

Scott, The PCH is ONLY open to 49! The slide will not be open for a LONG while! You CAN catch 101 at 49 and ride through to Salinas, though. Looking forward to seeing you and the bike Sunday!

[3Phase]

Congrats Scott, I figured it was just a matter of time and money until you got a new ride, and cure the cross country" do I make it all the way and back without issues" on our ol Ymmies. Sounds like HD got a great engine and cured all the issues over the last few years,,,so Congrats again, like the Wiz, used to say,,,,if it feels good between your legs, ride the heck out of it and enjoy the ride

Mike in Sun Diego

Thanks, Mike! "The Faithful" hate it, I plan to ride the wheels off it.

Hi Scott,
Congratulations on the new ride. Hope to see it in person next year.

Phil, I'm hoping to ride up to TGWN after I get my passport renewed, might see y'all next Spring or thereabout.

Well, it's a ride to visit, put miles on the engine, and test the seat while varying the RPM as much as possible so I'll take PCH as far as I can before hitting the slab. See you on Sunday!

Hmm, I wonder what Roo's been up to.

[ekim]

You guys doing anything of interest on Sunday for an older guy on a newer Yamaha? A ride perhaps? The FJR refuses to make starchy vegetable sounds though.

[DiverRay]

Yes we are! give me a call later today, or just ride over about 11:00am Sunday.

[3Phase]

Well, I'm in Salinas having dinner at the motel restaraunt. I just spoke with DiverRay and we're meeting at his place around 11AM tomorrow. Ride what ya brung!

Late to the party on seeing your new ride! Nice purchase. They put on new heads, is that to accommodate a taller piston so you don’t have to do anything to the bottom end when increasing displacement?

Thanks, Bones!

The Stage IV kit is an in-frame bolt-on with better heads, fueling, raised pistons and bigger jugs but no change to the bottom end, just a better inner cam bearing.

Unfortunately, I didn't get to the shop in time to take pictures of the SE kit before it was mostly installed and the new heads were on.

SE Upgraded Heritage 117 is 11:1 with coated raised-top pistons
Stock Heritage 114 is 10.5:1 with coated flat-top pistons

Hi Scott,
Do you have to run Premium gas before and after conversion?
What is the horsepower and toque gain?

It's supposed to use 91 Octane right off the showroom floor. The M8 does have real knock sensors to dial back the timing instead of the older ion spark detection system but playing with regular or midgrade isn't recommended.

The upgrade? It's totally awesome! I haven't put it on a dyno yet but it's a US model, not Canadian.
I can't really tell what kind of horsepower it has now but I just checked the garage and there has been no apparent toque gain.




Here's Harley's optimistic marketing 114 to 117 ci numbers from their web store.
The horsepower down in the sane band where I ride (80 MPH is below 3,000 RPM) is close to stock but it has enough ponies to keep doing that... for a long time.
Torque stays above 100 lb-ft across the board to redline until the rev limiter kicks in or it trips over the 107 MPH speed limiter.

[MaximPhil]

Hi Scott,
Left myself wide open to that one
Wow no wonder you went for the 117.
Interesting that they had to sacrifice low end torque for a very impressive gain in both HP and Torque.
5200 rpm looks like a wild ride.

Hey, Phil! Couldn't resist.

I still haven't really jumped on it and bounced it off either one of the limiters yet but it climbs right up close to the ton with absolutely no effort.
"Go directly to jail. Do not pass Go, do not collect $200."

From my bad memory, I think the loss is around 10 lb-ft. at the rear wheel but I'm almost halfway around the goldfish bowl so it's almost time to meet a new batch of friends -- and stop following me! (/Dory)

I'd worry about the loss if I had one of the heavy cruisers but it's a relatively light machine. On paper, it was about 80 lbs. heavier than my XS/XJ but it may be even less now. I ditched the heavy steel spoked wheels and solid rotors, then put on some aluminum wheels with lighter 2-piece rotors. I'll have to find a scale somewhere, it's something I really should know and write down in the manual.

The slight loss down low is from the increased cam duration, overlap and valve lift coupled with a larger 64mm intake and larger fuel injectors. It's almost too big to move fuel and air at low RPM but not quite.

There's no noticeable difference to me at low speed other than it's a little lumpy in parking lots instead of silky-smooth but that goes away the instant I touch the throttle. The biggest problem so far is keeping both wheels on the ground and watching for wet stuff so we both stay shiny side up!

Looks like it’s only about 5 ft/lbs down from 2500 RPM-3000 RPM. The time that may be a small hindrance is in top gear moseying along when you roll on. As if a guys butt can tell 5 ft/lbs when talking 100 vs 105 ft/lbs or 105 vs 110 ft/lbs... Drop it down a gear on back roads or through the city and get it above 3000 rpm and the “new” 117 will absolutely mop the floor with the “old” 114.

That is a serious power curve for the increase you get for just over $2500.

[DiverRay]

Scott,
You didn't mention the "floating" handlebars! I know after I was looking at your new ride I'd probably need some time to get used to the bars feeling like rubber bands. It does keep the hands from going numb, but I guess I'm just used to bars that are solid to the machine.
And guys, It DOES pull very well! 3Phase, ekim and I had a good time on the PCH a couple of weeks ago.

Yep, that's why I had the dealer do the install and roll it into the extended warranty. It doesn't smoke tires in every gear and break loose at 100 MPH on the highway or flip over on its back taking off from an intersection but it's got more than enough power for street riding.

The mufflers are showing a little black instead of the nice tan on the stock 114 so it's running a little rich. The gas mileage is pretty good so far, it's around 39 to 42 MPG without being overly conservative around town and it can cruise at 70/80 MPH out on the road.

I may or may not be able to get the dealer to tweak/update the ECU map but taking it to a 3rd party would be shooting myself in the foot (wrist?) and instantly void the factory warranty. From what I've read in a few tech forums, the new ECUs have a permanent section in their memory that keeps track of flash updates. Flashing in a performance tune and flogging the tips off it, then flashing it back to factory before taking the bike to the dealer won't fly any more.

Harley got taken to the cleaner by the EPA and I believe their dealers' diagnostic equipment beams everything up to the mothership when it's connected to the bike so you can bet your sweet bippy they can drop/decline warranty coverage even if nothing's wrong during a routine service. If there are any problems you'll have a new brick that you can put in the front yard to plant geraniums.

Overall, I bought this bike to run around town, cruise, tour, and generally slow the heck down now that my legendary imaginary skills and catlike reflexes are gone. There's enough power to get out of or into trouble and it'll pass cars going up steep hills but the floorboards, speed and rev limiters help reign in the more suicidal tendencies.


What an M8 looks like when the balancer grenades the case during a dyno run:-

The picture's from a 1st Gen M8 with the single balancer, Nanuk has two so I may get to enjoy her kisses:

It's two! Two! Two mints in one!

Ray, the rubber mounts on the bars are really stiff, I don't think you'd notice them. They don't do the rubbery thing for me unless I play horsey on it and try to push/pull the bars while kicking my heels forward and backward rodeo style.

The real annoying floating handlebar trick is accelerating and using the front 130/90-16 as an isolated vibration damper on the wheel and general direction suggestion indicator at speed for the bike while it floats over the road.

[Bonz]

Scott, is a reflash part of the upgrade to the 117? Meaning, would there already have been one? Take it back to them and tell them you don’t like the black exhaust color, that you preferred the tan from the stock set up. See what they say.
