Pulsing Front under braking?
 

Anyone here ever had that problem>?
Front end constantly pulsing at slow speeds when under braking?

Im inclined to think the disc's aren't alligned.

Sounds like a warped disc mate

Ian

else one or a couple of the pistons in the caliper are sticking.
A warped disc tends to show up however hard you brake, but if it's slow speed only ie light braking, then it could be a piston or two.
There are no dust seals on them, and they aren't rebuildable, so take them off, remove the pads and give them a really good clean.
Forcing the pistons out a way without the pads fitted will give you more of the piston to clean to.
After you've done it, spray a little lube (WD40) or better still smear a little brembo brake grease around the piston and push them back in.

Agree with Ian, that's probably the most likely cause.

I had the same on my blade last year, changes the discs and the pulsing dissappeared. Measured the runout on the old uns and there was the tiniest of error but holy cr4p did it come through the bars!

Well, nelly the expert beat me with the typing speed! Prob best to do what nelly says first!!

Hey, this is my 100th post :D
Kewl! Drinks are on me!!

sounds like a disc to me

Guys and gals
 

listen to Nelly
He's got more Duc knowledge in his little finger than Ive got in the whole of me
Many of us leave our pride and joy (the bike, not the wife, doh) with Nelly to work on and breath a likkle of his mystical magic into.
Im having a topend and hi comp piston job done at his place, and beleive me, my bike's just a 900ssie, and when you see him working on a 996 or a 748, then that IS a wonder to behold
Listen to Nelly

cheers ppl for all the info, got it checked out on its first service and they concluded a warped disc and are ordering 2 up for me just in case.
As far as seazed pistons go, I actually checked and cleaned but still made no ods as the pulsing is very light at higher speeds, probably due to the frequency.

Also another quick question for you ppl, since the service Ive noticed slightly higher running temps and the idling speed has gone from 1k to about 12k or there abouts is this normal?

OOOoopsss:lol:

Err not 1k to 12k :o

sorry, more like 1k to 1.2k :D

where do you live. If its in the Northern Hemisphere and above Watford Gap, a trip to Nelly's will sort you out.
OK enuff of the advertising (and Im not on commission) as the man and he'll give you a response, Im sure

Glad you've got it sorted Stu.
as for the running temps and tickover. If the mixture has been adjusted, and nothing else, a slight weakening of the mixture would give both the symptoms you described.
I wouldn't be too worried about it to be honest. Is the bike running OK?
It may have been running a little rich, prior to the service. Are the cans sooted up??
Keep an eye on the fuel consumption, and if the mixture has been weakened you may even see a few more miles to the tank.

Cheers Nelly.
The service guy did say to me that the mixture was off, as I was finding hard starting to the first service, as in full choke and a bit of throttle to get it to bang into life. First I thought it might just be the weather as its been pretty damn nippy. But since the service I took it home about 50-60 miles worth of run about 40 of which were motorways and the temp reached near 115. which was a bit of a shock as previously it hasnt risen above 100.

Calling Nelly, or anyone else that can help.

since the first service last Saturday, I said I experienced a higher idle speed of about 1.2k, well I know this sounds like a duff choke cable but the choke cable (idle lever aka ducati handbook) doesnt engage until about half way forward. now with bearing this in mind Im finding the bike tends to idle at upto 2k NOW but varies quite a bit from cold to warm, strange thing being the idle tends to settle at around 2k upto 70 degrees, and then drops to about 1.4k when warm. 100 degrees ish.

Also the bikes warming up much quicker than before and on some runs 30miles plus (not aggressive) its getting around 115 degrees.

My question being is this normal? none of the cables are sticking and are freshly lubed and have plenty of free play.

Stu, the linkage that the choke cable connects to isn't sticking is it? or getting caught on the cable etc.???
There is also a screw on the same linkage assembly and is part of the fast idle setting. This shouldn't be touched really when setting the idle speed or balance up, but if it's been tweaked by mistake, then maybe that's buggering things about???
I'd drop it back to the dealer and have them check it out.

PULSING FRONT BRAKES
 

I HAD THE SAME SORT OF PROBLEM WITH MY BRAKES. CHECKED FOR STICKING PISTONS & WARPING BUT ALL SEEMED OK. SO WHILE I HAD THE WHEEL RAISED I GENTLY TAPPED ON THE OUTER EDGE OF THE DISCS WITH A WOODEN MALLET, THINKING THAT THE SEMI FLOATING PINS MIGHT BE STICKING. DON'T KNOW IF THAT WAS THE CAUSING THE PROBLEM, BUT THAT WAS IN MAY AND THE BRAKES WERE FINE ALL YEAR AFTER THAT.

Pulsing brakes
 

I had a great one - took front wheel to a local dealer to fit a new tyre and when I re-fitted the wheel and went off for a ride guess what - front wheel under braking felt like the ABS on the car. One of the front Brembos was slightly bent. Went back to dealer who refused to admit any liability and it ended up costing me for a pair of EBC Prolite front disks. Best move I ever made as the brakes are now better than they ever were with the s/s Brembo disks

Thanks for the info ppl. I'll probably drop in on the dealers this weekend to see if they can take a look, suppose I best inspect all the cables in the mean time.

Ahh, the old hammer method. I always say, if you can't fix it, get a bigger hammer!:lol:

For Steve M....
 

..seems like a good tip, be careful how hard (or soft) you tap the disks
btw CAPS means your shouting and maybe not etiquette here, UNLESS YOU WANT TO SHOUT
OK sorry for the sarcasm and as you appear to be a newbie, no offence taken, just info m8

mort, fast ole fart:roll::roll:

HEY PAUL, CAN YOU HEAR ME!:D

lol..
k, hope everyones ready for this big freeze this coming week. DUCATI's at the READY!!!!

I get the feeling most aren't all year riders like myself. Come on lets stir a hornets nest here Im only a young un as most might agree 23 n all. but after 8 bikes owned and many ridden ive got a bit of experience. How many of you guys ride all year long or is it a bit too chilly for ya'll? :frog:

Stu, Im going deaf, but.........
 

my eyesights fine
Srri, not an all weather rider, at 55 yrs young, the chill does summfink to my joints (and I mean arms, elbows, knees type)
and my excuse for not riding at the mo, is........beasty is at Nelly's having some internal magic done , hi comp pistons to start with

Well I'm off outy in a minute before the snow arrives and I aint no youngster - nice to have a 916. Used to have a 900ss and the carbs would be icing up like hell today:cool:

Front End Judder
 

I had the same problem last year with front end judder. JHP replaced both the front discs and pads, cleaned and grease the calipers and pistons. The judder went away for a short time, but then returned. So back to square one. A friend suggested that the suspension preload could be out and the judder is caused by the suspension bottoming out. Not had any clonks from the forks, so don't know if that will work. Got some revised suspension settings from Sport Rider (http://www.sportrider.com/bikes/146_...ttings/#ducati) and the 996 instructions from PB, so will check against the factory settings to see if they are out at all and what the differences are with the new settings when the weather gets better. All that I know is it probadly looks like it is not the discs/pads/calipers that are to blame as I have only done around 250 miles since the replacements where fitted due to a knee op. JHP also checked the head bearings and fork alignment/tightness and they were correct. This is starting to really puzzle me now as what it can be apart from a suspension setup issue. Any ideas? Paul.

ah well had to be recovered by the AA today, seems that my idling problem just got a whole lot worse, its been gradually getting harder and harder to start since they changed the mixture after the first service and then now it dont spark.
So im tootling around a nice 800 monster for the time being, funny really cos that seems fine. First ducati Ive been on without issues;)
