clutch screach... brake chatter

[vivo]

Hey guys...

My 1100 Griso now has 1300 miles on it and since 600 miles has had two issues that haven't gotten better yet so I thought it's time to ask the other guys who ride this bike..

When braking and close to full stop my front brakes chatter. I assumed they weren't fully bedded in and did mention it to the dealer when I took the bike in for service at 600 miles, didn't know to wait until 900 but that does'nt matter. The point is that the front brakes still chatter and they haven't gotten better yet. This happens while gently braking and almost near to a full stop, they are also a bit grabby at that point.

The second issue is with either the trans or clutch which sometimes makes a screaching when the clutch is being let out. If I release the clutch quickly it's not present but if it's slipped even a bit the sound is there, noticeable enough to start to get on my nerves. Any ideas about this?

While I'm here I might as well ask another question... is the dipstick really hard to read, is the second line up the stick the full line?My bike was serviced only 700 miles ago and after a half hour ride I checked the oil and it reads just slightly above the lower line with the bike upright, off of course and the stick pushed in but not threaded. It seems a bit low but I'm not sure, as I said the stick isn't all that easy to read or it may be just a bit low and it's not reading near the top mark.

There have been issues with warpped discs on new bikes, but not for quite a while. I think there may have also been an issue with some of the discs rivets being too tight and not allowing the disc to float.
I too have the clutch noise occaisionally, normally pulling away from standstill. It can also be grabby furhter up the gearbox. I don't know what that is, so we'll have to wait for somenone knowledgeable to help us. I did have a thrust bearing go on my Le Mans II, think that was similar symptoms, but it was about 1980, so I can't really remember!
The dip stick is crap! The second line up is full. You're correct, don't screw the dipstick in to check the level. Someone suggested cleaning it of and using chalk (I think) to mark the edge so it's easy to read. Mine uses about 1/2 a litre of oil every 1500 miles, it sounds like yours may be similar. If you've warmed the engine up to check the oil, remember to leave it for 5-10 minutes to let it drain back. If you done all this and you're near the bottom line you need to top up.

Do you mean Chatter? or Judder?. My 1100 used to Judder with the original pads just as it was coming to a halt, changing to HH pads helped a lot but it woiuld still tend to do it in hot weather.

As for the clutch noise? No idea for sure but it shouldn't be making any sort of screeching noise. With the lever pulled in there may be a faint ringing at standstill but not a screeching. That sounds like a failed friction plate or a failed bearing of some sort. What year model is this bike and can you give me it's VIN #? There was a problem with a few 1100's where three bearing retainer bolts in the gearbox werem't installed but that was only on a few '06's I thought. I had one and it made a bit of a disconcerting racket.

Hey Pete and the other Pete

My Griso is an 08. I will post the vin as soon as I can see the bikes frame number.

I guess you can say the brakes judder. It doesn't seem rotor related as almost the entire stop feels normal with no pulsing and such. It happens just when the bike is nearin a full stop, a few miles per hour and until dead stop the brakes judder, feels almost like abs but not real abs. It's when the bike is very slow just near a full gentle stop that they behave this way. It has been hot in New Jersey and maybe it's pad material or some type of contamination on the rotors or pads, I'm not sure. I take it that this isn't normal and it isn't because the pads aren't fully bedded in? If so I'll let the dealer deal with it, it's his job to find the cause or replace the pads I guess?

The Screach is when the clutch is being let out gently from a standing stop. It doesn't happen every time and I can make it NOT happen by releasing the clutch quickly and not allowing any slip. Ot almost sounds like a belt or power steering pump on an old car! It makes that kind of noise and then when shifted it stops and doesn't return for upshifts. It's only from full on stop that it sometimes happens and it seems worse when the bike is hotter or after riding a while.

Ahhh and Pete, I may not have allowed enough time for the oil to fully drain back, I may have allowed only two or three minutes before trying to open the cap and check the oil so I'll re check the next ride.

Soooo if I don't know what the screach is it will have to be tended to by my dealer along with the brake thing and might as well have him write up the gauge fogging issue again. If water is causing damage to some gauges then I want it documented I've noticed it from new. I'm not worried or anything, at some point if it's not replaced then I'll try and seal it as it's been posted

hate to take the bike in for service again, the dealer isn't close and it's a bit of a hassle but it would be nice to have it looked to especially if the screach won't resolve itself on it's own...bummer

That brake problem just could be an ABS fault. I remeber a similar issue with an old car I had, which turned out to be a faulty sensor.
Try turning the ABS off, and see if it still happens.

We Grisoists are ABSless Brian.
Pete mine's an 06 bought new in the UK ZGULS00025M111802 do I need a fix, or just buy an 8v.

I had a similar issue with my Norge when new, which turned out to be a loose steering stem. Seems the bottom race was not seated and would slowly creep out of adjustment over time until it was fully seated. Try rocking your bike back and forth with the front brake on. Can you feel a "chucking"? If so, put a finger across the upper steering stem bolt to frame interface while doing the rocking and perhaps you will feel the slop there too.

Vivo,

For what its worth, my Norge clutch (16,000 miles) has a screach too, and your description is exactly as I would describe mine with one exception. My screach goes away when the bike has been ridden for a while. If I stop it will come back even I parked for only a few minutes and the bike is still really hot. But after a few starts from stopped, it goes away. And it only does it from a dead stop, and the sound is definitely happening as the clutch is in the process of engaging. Seems to work fine though, but it is worrisome.

Haha surrree I'll turn the ABS off

I'm thinking you were kidding me but they again?

Gday The cutch on my 06 1100 suddenly felt funny on the way to work one day.I made a stop on the way home and when I took off the clutch made a graunching sound. The rivets on the first friction plate had either broken or pulled through the plate,and this was the only thing that showed a used plate ,no trace of oil or heat.The seals on the clutch pushrod were found to be fitted backwards ex factory.I dont wheelstand the bike or do burnouts and I put the bike in nuetral before stopping. $200 AUS for parts and a bit of time making some tools and my bike with 30 000 has a new clutch.
I am not trying to scare people but shit can and may happen!! The joys of motorcycling.
