will the puller get the rotor ofF?
Wow! where did all those metal chunks come from?
those are magnets.... the magnets from the rotor.... srinath I believe is the expert.. and it looks like the puller *should* pull the rotor off but it's not wanting to go
FYI
The stator rotor popped right off with the gear puller.... I tapped on the side of the magnet rotor with a dead-blow hammer; and after a couple taps all around and tightening down that puller it came right off....
you should have that checked out. no one likes a bike with goat's syndrome... especially me :)
Yeah, I had to hit mine a few times before it popped off. And then proceeded to fall on my tank. It didn't have a mark on it before that happened :(
I hope that you get it fixed quickly. It looks all too familar...
well I have a stator and case gasket on order... I've pm'ed someone who has a rotor magnet... and tommorow I'm ordering an oil pan gasket so I can remove it to clean the screen to the oil pump
sooo.... hopefully I won't be down too long. I'm a little worried about long term engine damage though :-/
Yea goats syndrome is contagious :lol:
BTW clean out the pan and filter screen, and mine has not had any damage, and I had it bad. Oil and filter change every 100miles 3-4 times... and you should be home free... like I said... could have been a lot worse.
Also I feel like a schmuck... I should have gone to check it, and the battery non charging and the fuse blos as you turn it off whould have immdiately told me to look at stator for ground, and that would have told me possible goats syndrome... I'd have known in 3 mins what took you this long - 1.5 weeks ... having recently fallen to goats syndrome I am very sensitive to it... :lol:
Cool.
Srinath.
wellll.... it's not too bad. I probably might have still bought the bike... plus I'm enjoying working on it!
What is the # for parts depot again? (so I can order an oil pan gasket)
Thanks!
Jacob

btw I think my bike caught it from your bike when I was visiting... I TOLD you we should have kept them apart!
Parts depot is 800 245 3101, order a whole gasket kit... you'll need a right side as well cos you wanna see that for metal??? or maybe not.
Cool.
Srinath.
okay.. I pulled the oil pan (WOW that thing was stuck on there...) I did it without tipping the bike over as well.... It really wasn't too bad at all...... Had to do it all laying on my back (then again all the work on my car is that way too so........)
Oil pump screen is SPOTLESS. There was a little bit of gummyish oil on the stainless piece covering part of the screen but all in all..... NO magnet specks.
I really think I ended up lucky in my case of goats syndrome.... My magnets were (for the most of the part) intact. My stator was broken; and my RR might be broken (got another just in case... but my battery wasn't swollen at all...) and my magnet rotor came off really easy.
I also removed the oil filter. It was clean as well. I mean, it was a little dirty from oil and a little gunk but NO magnet particles/flakes etc. The bike was also running perfectly other than not charging the battery.
okay couple questions:
will regular 10w40 motor oil work?
do I need to glue or epoxy the magnet rotor back in place? It WAS glued in place when I took it off.... I don't see what keeps it from not turning.. there doesn't seem to be a "notch" or anything (but then again I haven't looked hard...)
The taper locks it in place... the technique for putting it back...
Get the starter clutch assembled, and the gear in, else the starter clutch will escape... then hold the 2 together and pu it on, and get the bolt in, then the idler gear engaed to the starter clutch gear right... get that matched up and set right, and insert a penny between the idler and starter clutch gear, and crank that bolt in... BTW the gear starter clutch gear should spin freely if you try to turn it clockwise looking from the left side of bike and engage and not turn if you spin it counter clockwise... the bolt holding the rotor... exact opposite with the penny in place...
Cool.
Srinath.
hmm... my magnet rotor has a place the put a wrench.. like a 22mm wrench (or even large... maybe 24...) so I don't have to use a penny I don't think..

I didn't understand that at all, but I'm so glad Srinath's in the GS500 camp :) .
Does anyone know what kind of "sickness" causes "goat's" syndrome?

Yea and you need one of those crow feet wrenches ... else it will slip off... or you can heat and bend a regular crescent wrench into a dog leg...
Cool.
Srinath.
Somebody send this man a camera! ;)
I am the only one to have a reason for goats syndrome...
Some history here...
First up ~3 months ago was goat who posted his bike clunking and running like crap, and while his dad said nothing was wrong with the bike,goat felt somehting was off ... and starts taking it apart and I believe he opened up the top end ... working his was down... BTW I think a bunch of us guessed valve hitting piston, or bent valve or some other head issue ... and he finally opened the left side case and posted a pic of his rotor that looked like it was eaten by a rat... His had 5K miles on it ... so in true medical tradition we name the disease after the first patient...
2 weeks after that... my 43K miler which had been clunking like crazy at startup for 6 months while I said "its the starter clutch... and I'll fix it when It stops working all together... " after a 80 mile ride on sunday some of whihc were clunkier than usual... cos it was making it sometimes at low revs ... monday morning it had a dead battery. I thought about it at work on monday and knew pretty much goats syndrome is likely... I go home and charge the battery, and test the electrical system... and stator shors to ground on 1 line... and reads low on all 3 ... bingo... open up the case and the rotor is shattered... 2 magnets completely gone, 2 more ~50% gone, and stator has many many impact craters... I pull the cover off and literally 99% is in the bottomand on the brackets etc... I yank the oil pan off and the screen is loaded with a few magnets and a ton of lacquer... I pull the right side off and its clean... so I swipe the parts off the motor I have sitting about, buy a new gasket set and a starter clutchand re assemble the thing. I change oil and filter after 1 ride ~20miles, then every 100 miles for ~3 times ... and now 3K miles later it showed no permamnent signs of goats syndrome... BTW after the first ride I took off the cover and checked if my magnet is still rubbing somewhere...
The starter clutch clunking sends some severe vibrations through that part I think... it will shatter the magnet with repeated abuse.
se7enty7's bike - 13K and no starter clutch issues... and went down with a light case of goats... no reason though a drop on the left side wihtout case savers might be to blame... like davipu who crashed on the right and it took out his ignition parts... I have crashed on the left and heck I have been clobbered by a car on the left and made 30K miles before mine died from goats...
So I guess any impact to the left side and starter clutch clunking ... and no reason at all are all causes of goats syndrome.
Cool.
Srinath.
mine was making NO noise at all. My battery wasn't charging; and the bike was ridden about 50~ miles since it had stopped charging. The previous owner said the he thought the battery was dead and stopped riding it for the most part.
So.. mine wasn't bad at all. Only a couple cracked magnets and a couple of magnet crumbs stuck to the magnet gear. I found nearly no pieces anywhere else (there was a small piece in the oil pump screen. 1 piece..) and NON in the bottom end.
Word to the wise.... I have a feeling had I driven it much more I would have cause it to be much much worse. The more it's driven the more the magnets seperate and hit the stator.
Goats Syndrome -- GS - se7enty7 you have GS...
Cool.
Srinath.
i've had a few dreams where i got the syndrome. im a wack job i guess haha
For those that have had their stator break apart, has the bike been down of the left side? Not just a stopped tip over but at speed. Did you inspect the inside of the case cover for cracks?
The reason I am asking...I have another members case cover that had been in a crash. It is scuffed on the outside but is not ground through and held oil fine. No immediate signs of other damage. But there are extensive cracks on the inside, especially around the mounting boss for the stator. These cracks could lead to failure of the stator due to being out of alignment of the magnet.
From se7enty7 pic of the stator, looks like there is epoxy on the inside.
Nope on mine...crashed many times left and right, but 35K was the last one ... GS at 43K... and 4 years later ... BTW mine was almost certainly starter clutch clunking which I ignored for 6 months ... But its old hat by now...
Cool.
Srinath.

there is epoxy. IMO I think that's what caused mine.. here's why. I bought a BRAND NEW stator, and an assumed brand new magnet. Guess what happened on FIRST startup? CLUNK CLUNK. Broken magnet, broken stator.
Either my crank is bent (unlikely) or my case cover is bent/jarred. I bought a case cover with a stator and am looking for a magnet..
If a chunk broke off would it be possilbe for it to crack the engine case?
Derek
Mine was wrecked on the left side

I guess it would be possible to damage the mounting boss of the stator (and crack the left case cover) if the magneto and stator came in contact with each other while the motor was spinning.
Hmm... I seem to have missed the later parts of this thread
Quote from: dgyverFor those that have had their stator break apart, has the bike been down of the left side? Not just a stopped tip over but at speed. Did you inspect the inside of the case cover for cracks?
My bike looks like it was dropped on the left side before I bought it. I don't know any details, however. There were some small cracks (I'm not even sure I would call them cracks) on the inside of the stator cover but I don't think that they were damage from a crash. I think that I have a picture of it. I'll post it later today if I can find it.
Srinath disagree's, but I am convinced (convinced!) that mine was caused from a crash that disrupted the stator cover. Mine had stress cracks and was actually broken (there is epoxy in the pics that repaired it) before I bought it.
I didn't find this out until buying a NEW stator, and NEW (used) magnet, and they BOTh got destroyed when first starting the bike. Now I've got a new case cover, new stator, and used magnet. So.. hopefully it goes better this time.
Is there a special trick to getting the case cover on without letting the stator get magnetized to the magnet? I'm going to use two or three longer bolts as "guide bolts' to get it on.
I dont disagree ... just that mine was not from that ... BTW the case guards are cheapinsurance that goats syndrome doesn't happen like an epidemic ...
Cool.
Srinath.

ohhh... I thought you said mine probably wasn't cause by it.. :dunno:
yeah srinath's case guards AREN'T coming off my bike.. lol
Quote from: se7enty7Is there a special trick to getting the case cover on without letting the stator get magnetized to the magnet? I'm going to use two or three longer bolts as "guide bolts' to get it on.
Yep, that is the best way I have found to do it.
AHHHH it's FINALLY over!!!! I replaced my case cover, stator, and magnet. When I rev to 5k my voltage jumps to 14.5+v.... (near 15?) Yay!!!!
Hopefully my RR isn't bad as well :-/

My experience to add to the Goat's disease research (maybe we should set up a research fund :roll: ):
Here is what I foundWhile my magnet did not shatter, the epoxy came off the magnet and I am guessing it is from a slight impact.
Back in early September, I was hit on the right side by a car at fairly low speed, then my bike went on its left side. The impact of the car was enough to knock me off the bike and take out the ignition parts and break the crankcase cover.
On the left side, the only damage I noticed was a bent footpeg and scratches on the handlebar and stator cover. I never thought any more of that. My hypotheses are that (a) the impact on the right side was enough to send a shock through and knock the epoxy loose, (b) when the bike went down to the pavement it was just enough to knock the epoxy loose, but not break the magnets, or (c) none of the above, it happened before I owned my bike or just at random
yup... so anyone with banged up case covers might want to pull them off and take a look
in my case, my left case cover was bent... so I destroyed 2 magnets and 2 stators.....
Those bloody goats i tell ya...... :guns:
My case cover is scratched. Do I have to drain the oil to take the cover off?
Well The oil will slowly drip out ... you might lose a quart in a month if you let it be ... but you're taking it off a few mins ... makes no diff will drip oil when its full or drained ... cos that cover gets a bit of oil and that will not ever get drained off when you drain your oil ...
Cool.
Srinath.
Quote from: DomMy case cover is scratched. Do I have to drain the oil to take the cover off?
If you lean the bike to the right the oil will flow away and you can remove the cover without draining. Even if you decide to drain the oil, drain it in to a clean container and then you can put it back in afterwards.
