696 Ehaust Sound Change?

[DucatiTorrey]

I have a 696 with termis, DB killers removed. love it. anyways, we've talked about it on here before, how we love to decel and let the engine pop and rattle and scare the shi& out of people. It's wonderful fun.


But my question is this. Does yours still have the same thunder after about 3000 miles? Mine seems to have settled down a bit, no more popping (well, a little, but a severe drop) and rattling, back firing when i engine break anymore. its kind of worrying me. The shop here said its just everything is working in sinc now, and is all broken in. If that's the case, i liked th sound way more when it was brand spankin new.

anyone else? Broken in wrong? i thought i followed the rules.


on a side note, i had a bad oil filter from ducati (didn't know they made them, unless i was fed BS) took two visits and  days to figure out where the leak was coming from

anyone else here?

Backfiring and popping on decel, isn't generally a good thing. Be glad it has cleared up. 

[DucatiTorrey]

well, it wasn't a problem thing i guess, it was that split second i think there was slack in the chain maybe? anyways, just added rumble i guess you could call it

thanks though for the reply

Popping like is a common symptom of a leak in an exhaust connection  - so it sounds like you might have had one that cured itself

[ArguZ]

You could fire a shotgun while riding..
Or drag a sledge hammer behind you for sparks
That would also give a nice rumble when breaking hard, maybe even popping something 

No seriously, its good its gone...people will not throw beer cans after you in the morning and you system will last longer.

i have a 695 with the same setup, and after awhile i felt like it didn't sound as mean as it first did. After some deliberation i realized that i had just  gotten used to it.

i kinda noticed the difference. i mean i really have to chop the throttle to hear the pop. (when coming into a town after a few kilometers sprint)
i figured the motor is smoothing out with use. not a problem for me.

agreed, thanks guys (and gals?)

its probably a good thing, as long its not me going def...

My S4Rs is as raucous now as it was when I had the full Termis installed along w, an Open Air Box 3,000 miles ago.

The 1098 R has the Full on Race Termis and it still after 3941 miles sounds like it did when it was new.

At a certain RPM  in 2nd gear it sounds like several hammers beating the inside of a 50 gallon drum. Most noticeable when going through small towns at about 25 mph.

No Backfiring.

If I don't have my Earplugs sealed in my ears when riding either of the 2 bikes I can't take the sound. It's loud but not Harley drag pipe loud. No noise killers in either.

I don't set off car alarms like I used to w, the Harleys and the Vance & Hines Long Shots w,out Baffles.

You left out "at 2 in the morning."

I'm at just under 3k, with about 2500 on the termi's and mine is as loud as it was before, pops & everything else. I love it, very hooliganish.  High RPM's & Off throttle are the best noise they make.

the word you guys are looking for is "overrun" and it's perfectly fine for the engine to sound nasty on overrun. It's actually a function of fuel mapping (that's why pure race engines do it more than street engines) and silencers. If you remove the baffles, install aggressive pipes, or anything that exposes more engine noise - you will hear some. If it's truly changing on non-changing set of exhaust, then it's probably driving habits or fuel mapping. Most modern ECUs are adaptive. If the Monster's ECU is adaptive, then it will run more tame if you ride more tame. The other side of that is even at a given set of fuel mapping, the way you come off throttle and go into overrun will affect how much of that sound you get.

i find this "overrun" happens more if the bike hasn't been driven in a couple days too. Also, its more "tame" and a jaunt on some slab. this is interesting though, i wonder if it is adapting to my city riding, etc...  i do more around town riding i guess. then get on it hard in the country.

it has the Termi ecu btw, anyone know if it is adaptive?
