Hi Guys, one last recomendation I would like to give is always, mean always, check the vacuum level after installing the new pipes on the brutale R. This is of high importance after installing the pipe and the new chip, as it affects significantly the smooth primarly in the transition from low to mid revs and from mid revs to high revs.
After rechecking them myself last friday I found cylinder 3 and 2 vaccum level to be down compared with 1 and 4, primarly the 3rd. After putting them alined, with the most sensitive possible, I found a new bike.
Now I can say the bike runs really well, powerfull from 2000rpms up to +12000. It becomes dificult to keep the front wheel down up until 3rd gear.
I am running with 100 ron fuel or 98 ron, and the CO% measured at 1150rpms/1170 rpms is 4.5%
TPS is at 2.1º

Whoa James, that's an impressive image. What RPM? I generally look for <1cm Hg from idle to 4,000 but only find a couple of spots where everything comes together like that.

You have done that yourself, Manuel? :wtf:

Hi Miguel if you want to know if it was done by FMS the answer is no.
I took the bike to a shop where I could find a vacuum analiser, digital, linked the vacuum pipes to the machine and easily set up the vacuum level.
It was a ducati "specialist" shop. Has there wasnt the MV software we did measure the tps in mv, compared to Ducati table and if you check the ducaris before the new generation used the sema magneti marenelli 1.6 as our Mvs does and the voltage found was precisely 2.1º.
So after checking the TPS (voltage) gone to the vacuum and finally the CO%.
These are really easy steps if you have those pieces of hardware, if you dont like me, just find a place who has.
If you need more info please phone me or send message. Will be nice if I can help you.

Thanks for the tips and help offer :smoking:
I may check that, one of this days and i will surely do it if, when, i install an open exhaust. I'll give you a call when before i do it.

And it's not Miguel, but Tiago ;)

Hahahah, no problem ;)

Sure :smoking:

You do the same when you come down here :)

I envy the engine aptitude of many on this list. I am wondering if my 910r suffers for this attention. As posted on another thread, my bike cuts out when coming to a stop or just idling. It usually make a hiccup sound, recovers and then repeats without the recovery. It is getting worse over time and I have a call into the dealer, who tell me that 2 others have reported the behavior following chip installation.

Should I suspect that vacuum levels are out of sync and should I send this guidance to the dealer? They tell me that they are seeking assistance from MV, but I have not heard back from them.

Thanks,
SteveC

Although I don't really experiment much anymore - when I first got all the gear I did quite a lot. I wanted to know what did what exactly.

I've found that TPS is really a rare adjustment if ever.
I set up the throttle body balancer and exhaust analyzer together to watch the CO while balancing and get it as close as possible without messing with the ECU POT.
Once I'm happy the balance, idle and CO are as close as possible I move to the ECU POT.

I've found on these bikes, 750 or 1000, if you get everything right at idle and at fast idle it is great throughout. I used to closely watch at high revs and at changing revs but to me it makes little to no difference - and believe me I've done this quite a number of times on a few different bikes :)

Here I was bringing #3 in line. I do often end up with #1 or #4 very slightly different than the rest no matter how careful I am at filter/airbox/trumpet assembly..I just can't get them in line and still stay in range with the bypass screws.

Hi Steve, I think you and everybody who changes headers should check the vaccum balance between cylinders, this is crucial for the low to mid and mid to high rpms evolution, in my prespective.
Regarding the stalling I think that has to be with combustion and it seems to be more frequent with higher levels of Co%. Iridium NGK also seem to work better but I have no personal experience with those, only heard about it.
Please make all TPS, Vacuum and CO adjustments but I dont beleive it will affect the stalling problem unless your CO level is farway out from the maximum 4.5%

Hi ,ive had the exhaust done on my 910R,just like to ask that when my pipes were changed should the dealer have checked my vac ,after istalling exhaust and chip ect.

Thanks Manuel for the guidance... I have reported the issue to my dealer and they are working with MV to investigate. As I don't have the necessary equipment to test myself, and wouldn't be qualified to, if I had... I am hoping they can figure out something prior to me driving it back to Houston...

Steve c, did you get your work done at BMW Dallas? I am not sure whether they did my vacuum either but the bike works well. They are stand up guys and the price is actually real good. put my pipe on and did my 600 for like 270 dollars! no valve adjusment but I understand that is common. I am just wondering if there is a lot more power in my engine that I am missing by doing a little added tuning?

I had the exhaust installed at Houston Motorsports. I had 4200 miles on the bike, at the time, and no issues (aside from the traditional excitable throttle).
Following the installation, which cost me $260 (4 hours labor), the stall or cut out issue has surfaced.

The dealer is 160 miles from me but Dallas would be further... I may call the folks in SA, if I am not able to make progress with Houston.
