Hyper S... Termis and Cams - Ducati.ms

breakdown · Jul 7th, 2008, 12:05 am

Hey,

I'm trading my 848 in on a Hyper S tomorrow. After putting about 3,000 kms on the 848, I decided that it just wasn't the bike for me. I test rode a Hyper S and had an absolute blast on it. It reminded me of why I got into street riding in the first place. Since I do about 70% of my riding around town, I think I'm going to fall in love with the Hyper S; I can't wait.

I'm just wondering though, I found the throttle response a bit sluggish compared to my 848. The Hyper S was stock so I'm wondering if the full Termi system, cams and ECU will liven it up a bit. My 848 had a full Termi system as well and it just seemed so much snappier in response to throttle inputs. The Hyper S had great power but it just felt like it came on in a much lazier fashion. Not really a big deal, I'm just hoping that I can make it a bit snappier with a pipe and cams.

Thanks

I've fitted termi full system, cams & lightweight flywheel and it has livened the bike up. Haven't ridden an 848 yet so can't offer a comparison.

The cams won`t liven anything but your top end. Get the full system and lightened flywheel for sure. I actually thought about taking my dp cams out after I installed them. Lost some grunt to the tune of about 4 ft pds on the dyno. Got it all back and some after installing the high comp pistons. IMO do the pipe and flywheel since you`re mostly around town and see how you like it. BIG difference. You can always do the cams later...

+1 to friques comments. All the data we have seen so far about the cams is that you end up with less torque and a flat spot on your torque curve that is not there until after you put them in. If you want cams then make sure to do some piston work or at least a PCIII to get it set up properly and then it will be good to go. I had a 1098 and the Hyper was just as smooth and crisp on the throttle with the full exhaust system. I had it stock for about 500 miles and it made a notable difference in that area after install. Seems like that is what you are going for so my advice get the full exhaust or a comparable set up.

Interesting that my total stock hyper S has a very uncomfortable, twichie,surge off idle throttle response. This makes the bike hard to have fun with coming out of corners ride fast etc. Others have agreed and say a new exhust system will help a little.
Now you report a sluggish response the opposite of my experience.
I wonder if my October delivered machine has a different mapping/ECU.
If newer machine have made adjustments. If so, I want it as a recall item.
Honest this machine at 2000K is a lot of work to enjoy and it is unacceptable that Ducati has not offered a fix for free for us who leave are machines stock.

If you are set on keeping the stock exhaust, here are couple of things for you to try to address some of the snatchiness... Try adjusting out the slack in your throttle cables, leave just enough slack so that your idle speed does not increase when the handle bars are turned full lock in either direction. You can also try removing the cables from your exhaust valve but leave the servo motor connected. You may get an error code but your bike should run a little better.

I would agree that a less restrictive exhaust and intake along with some fuel mapping adjustments is the path to really improve the way your bike runs.

I'm pretty darn sure there is something on page 4 or 5 of the U.S. Constitution that all Ducati's must have the stock exhaust replaced

But they shouldn't have to just to run correctly.

Thanks for the advice on the cams; saved me some money there.

I can't wait to get the full system on. It just doesn't sound like a Ducati should with the stock mufflers on there.

The lightened flywheel is a great idea. I never thought of that.

Has anyone re-geared yet? I haven't had a ton of seat time yet but I'm hardly ever out of 3rd gear around town.

The only other thing I think I'm going to do for now is the 20mm shorter seat. Would that be a good choice or should I get the race seat? I definately would like a slightly lower seat height.

I'm also going to see if the dealer can lower the bike by 10mm by adjusting the suspension height without messing up the handling. If rear ride height is lower by 10mm and the forks are raised by 10mm in the triple clamps, will those changes balance each other out and not affect the handling adversely?

The bike is an absolute blast so far! I'm so happy that I traded in the 848 for my new Hyper S. I do most of my riding around town with the occasional trip to the canyons. The Hyper is a blast around town. It's just so easy to toss into low speed turns and then wheelie right out of them. I can't wait until I get more seat time and get more comfortable on this bike.

any lowering is going to effect the handling but honestly if you have your supension set up for your weight and only lower it that much you probably wont be able to tell a difference.
