Clutch Whining
Clutch Whining
Just wanted to see if anyone has experienced a problem I am having with one of engines. There is a failry high pitched whining/squealing type noise (loud) coming from the clutch basket area at low revs. Over a few grand the noise goes away. I have changed the large roller bearing that the basket runs on with no change.
Oh and I think the bottom end is an FZR.
Any advice appreciated,
Cheers

It's an engine I bought off a guy that hadn't been run for awhile. He assures me there was no such noise last time he ran it. 
No change with with clutch in or out or in gear. In fact I ran it briefly with no clutch plates or hub so as near as I can figure the only things spinning are clutch basket, oil pump and water pump. Changed the water pump and i don't think it is oil pump. Sort of hard to explain but it seems like the clutch basket itself but i can't for the life of me figure out what would generate the noise. The hub has been replaced at some stage as the rivets are not orginal. One of the tangs is broken but apart from that it looks OK.
I guess I could go to the extreme and pull another engine apart to swap bits. Bloody frustrating though!

You may need to pull the basket and look at the backside. Maybe a bent ring gear? You did say that the rivets didn't look original, so I'd definitely pull the basket and look the whole assembly under good lighting.
There are some who call me........Tim?

gotta look in behind all the frictions and steels, they crack at the rivets apparently.

Yes Yes I know, I said, I'm building a project YZF1070
Basement is done now, 850 finished and gone...
Gotta get the new siding up on the house.
Fixing the FZ1 up, cleaning up garage and then I might even begin

Face it Mike it's f**ked. Send it down and I'll have a look
If you think about wheel bearings, they squeal when they are 'done' the only bearings as such are in the gearbox.
It won't be crank as plain bearings generally only knock, straight cut gears can whine but it is doubtful, probably a gearbox bearing? If the clutch basket was spinning so is the gearbox. Does it still have starter and alternator fitted? If so it could be alternator or related bits and pieces on that train.

Don't know about it but I am!Face it Mike it's f**ked

I actualy had the plates and hub out so that should have stopped the input shaft and gearbox from spinning? Changed water pump, starter motor, ditched alternator. It has gone in the to hard bin for now. Will try and get back to it next week.

Oh jeezus... It was crap.
Okay, here's copy of an email answering the question sent after Jason lagged on me to a mutual friend...
it was wet for the first two sessions, and I had an oil leak from the clutch cover. Had a strange wallowing in and out of turns, but i think tyre pressures might have been a bit low for the type. Couldn't find any other reason for it, checked head bearings, took the damper off, backed of compression and rebound at the front a couple of clicks, checked the rear settings were at base etc. Last (3rd) session it felt better and started to push a little, but the oil was starting to hit the exhaust and the rear, so that was the end of it for me.
Jason went well on his 89 FZR, in fact he quite liked it. I think when he finally sheds the remaining 30 surplus to requirement kilos, he will be a force to be reckoned with!
In addition: the last session was without damper on a TLS at pretty much full pelt over the bits that would tie anything into knots. It was fine
Edit: Greg Leach editor of one of the trader mags wondered by and asked if the red bull can made it go any faster... I answered it will make you go a little bit when I stick it up your arse....

Yep, mines the same but more of a pronounced whine (could be a pom stuck in there...), but I only notice it cruising back up pit lane after the race in 2nd - and no it's not coming from 2nd gear.
Having just done a total nut and bolt rebuild of the motor I'm a bit stummped myself about the origin of the noise, but I suspect the primary gear may be the culprit (and I have taken out starter drive and alternator so It's definatley not coming from there).
I'll have the clutch back out soon when I fit the falicon clutch basket

If it is this, it could be because the hub has come from another bike at some time.
Anyway, I suspect this could be the source of your noise as well.

Cheers Kiwi. I only have spare YZF750 clutches or else I would have just changed it out to see if there was a difference. Could try the one out of the Peter Jackson but I am riding that this weekend
I will update when I eventually figure it out and look forward to hearing what you find.
