Roughness between 3K and 4k RPM and other issues

agsurf5 · Mar 22, 2015

I have a 2013 Hyperstrada. Recently got it and love it.

When I am cruising at low speed, 55/60mph, between 3000 and 4000 rpm in high gear, bike is rough. Almost sounds like it is missing and recovering. That happens at any mode. As soon as I am above 4000/4500 engine is smoother again. Do you guys experience the same?

Based on the bike history, both clutch and throttle body were replaced already by the previous owner. Bike has not much warranty left, so I was wondering what else I should look into as for '13 failures.

Try a lower gear....

I love that there is always some smart a$$. Who is going to tell me to go faster?

Point is that an engine for a 14K bike should be smooth at any rpm range, and 3-4k is quite a normal range for a 2 cylinder engine. I shouldn't have to go faster or change gear.....

Does not sound right. I would have the dealer check it out, see if they find the same roughness that you do. I have a '13 and don't have that problem. If I am coming off the gas there is some hunting before it settles in to an rpm, but no roughness or missing or flat spots. I only use sport mode and really like the quick response.

The bike does naturally chug below 4K in the lower gears. There was an ECU update that somewhat addressed it and throttle response a while back. Check that it's had all it's software updates.

Any details on why clutch and TB were replaced? I haven't heard of any replaced for age or wear.

What type of gas do you use? 31 and + right?

agsurf5 · Mar 22, 2015

Yep, using good gas.
I just saw the ECU update on another post. I'll have it checked by the dealer this week and see if that address the issue.

PS previous owner complained about clutch and had it replaced, and also apparently had the issue where the throttle remained open instead of closing. I read around and I understood it happened to few people.

If your EVAP canister is installed.. Make sure the vent line isn't kinked..

@agsurf5

that normal for some Ducati Bikes the Monster 1100 EVO is even worse!
Software update will not help you! Maybe a 14 sprocket or Rexxer ECU tuning this will shift your problem to a lower RPM 2000 to 3000rpm. Coming from the Monster 1100Evo I have no problem at all with that!

Is this your first Ducati?

All 2-cylinder bikes have this problem more or less. The leaner it runs the worser it is, basically.
I had a Guzzi Stelvio befoe the HS and there this occured below 3000 in 6th gear.
Have you ever driven a KTM SMT ? You would not complain about the HS.

I am surprised that it runs quite smooth at about 3000 in lower gears, even i feel a little surging there, but not bad and acctepable. And above 3500, better above 4000, the HS runs really smooth.
My guzzi had this much worser until i deactivated lambda sensors.
Actually i have to drive my HS 1000 rpm higher than i did my Stelvio

Unfortunatly former DucatiDiag (now JPDiag) - http://jpdiag.akress.com/ - does not work with our new 7SM ECUs. With that you could deactivate Lambda sensors and bike ran in open loop via internal mapping all the time. No closed loop any more. Most bikes were not recognized after this little "SW surgery" so smooth they run without lambda regulation.

Thats the reason for Fuel Controllers like Rapidbike, PC5+WB2, SW like Rexxer, .....
The simplest way, if possible, is to deactivate Lambda and fully run over the map directly.

No one is telling you to go faster-the suggestion is to keep the revs up.

Point is -14k or not 14k you might have to shift. It's easy -pull clutch- push lever - release clutch. Part of your 14k went towards this fantastic feature.

There is no Point with the Engine, for you it's better to sell the bike and the only smart a$$ are you!

Calm down, guys. It was a sane question. Having owned I-4's my whole life, all I heard about twins was the "insane low range torque". So, I naturally assumed that twins just live down low. I was surprised how the 821 was grumpy down low and actually liked being wound out.

I can vouch for this, only had I4's and V4's myself - I've never like V-Twin's having only rode 1000cc plus ones before. That's why the 821 shocked me - it actually felt lively!

Still, I second the fact that it doesn't really enjoy being below 4000rpm...

And I didn't understand the difference between I4s, V4s and twins....just know that at lower revs, in the higher gears, the Hyper tends to get rough...so I select a lower gear.

Now....I wasn't taking the 'piss out' of agsurf5 and agree that the question is valid and my respose could have been taken the wrong way.

What I recongised after reading all the responses is that we have many riders from different parts of the world.....some with English not being the mother tongue...so it pays to be careful in how you respond and not quickly during a break at lunch, like I did.

And agsurf5....I'm not suggesting you can't speak English...just so we're clear on that

(now this is taking 'the piss'

are Australians speaking some kind of english ?

Very interesting conversations on differences between similar engine configurations. I grew up riding air cooled Honda 4 stroke air cooled dirt bikes and switched to the modern 4 stroke motocross bikes. Even though they are both single cylinder 4 stroke engines, compression levels and piston strokes are completely different making them have totally different power characteristics at different RPM's. Old air cooled 4 strokes were called "thumpers" because they liked to be lugged and made a most of their torque at low rpms and didn't rev that high in relation to the new liquid cooled ones. Modern 4 strokes make power from the mid range all the way up to the much higher rpm range. I've owned and ridden many twins and the Hyperstrada is not a happy lugger. It reminds me of a modern motocross bike. It is happy and smoother in the mid range (5k-6k) and simply screams as you rev it out. I am still amazed every time I ride the bike at the sound and power this 821 puts out when you wring it out. Ride your Hyperstrada after hopping off a Sportster 883. Same number of pistons in a "V" (90 vs 45) configuration with roughly the same displacement but yet 2 totally different animals.

@AussieHyper
Thanks for the clarification. 15 years in NY make me understand english well enough, but biased towards the insulting side of it. I hope California will reverse the tendency....

And for @Appliance821, yes, I bought the HS thinking it had an automatic transmission. I used to ride Cadillacs and I did not realize motorcycles had to shift. So I am having issues with gears. Can you please write a detailed post on when to use 1st, 2nd, ...6th gear and how to shift? The 14k manual does not cover it enough that amazing feature.

After the "piss out"....
So basically most of you are having the same issue? With the bike in 6th gear and cruising without changing throttle at 3500RPM, the bike misses and sputters.
I have ridden many other Ducati in the past of older and newer generations. Never the smoother engines, but never so rough.
I also have a triumph, and that twin is smooth at any rev.

no, no misses and sputters, just the feelling that bike wants more revs

BlueSwede · Mar 25, 2015

No, it does not miss or sputter. I still think you need to have your bike closely checked by a good Ducati mechanic, and make sure you have all updates. Lots of folks reported better smoothness after ECU updates.
