alright so i removed clutch cover and everything is in order no metal shaving or anything that isnt normal. just now i also removed stator cover and gears look excellent no shavings or anything like that. right now im thinking that something broke somewhere more internally like a piece of tensioner and its blocking something at one point. the engine actually rotates 180 degrees not 1/4 turn like i thought before.
 
ok i found it dont know how i missed it the first time one of the lifter nuts is gone. :o how far can it go how deep do i need to disassemble already tried magnet but chain is the only thing that sticks
 
If you take the clutch basket off you can see the crankshaft
 
Sounds like the missing nut might be caught in the cam chain. Try rotating the engine backward to see if it falls to the bottom.

As mentioned, you can see a lot of the crankcase by removing the clutch basket.

Next easiest access is by dropping the oil pan, but you usually have to remove the exhaust to do that.

.
 
thanks guys i'll do that tomorrow, i thin the nut is at the bottom of the crankcase by looking at the manual i see that one of the shoulders of crank has cuts and then the rest is round i think thats why it allows me to rotate it between the cutaways. now i need to find clutch cover and stator cover gaskets as mine are gone.
 
^^ thats what im thinking
i took primary gear off last night and found absolutely nothing. most likely it went under the chain and is on one of the teeth of the crank chain sprocket.
I am a bit at a loss right now of what to do option one is to rebuild this engine which is in prestine condition all the gears mechanisms everything looks just wonderful almost factory fresh. But gaskets alone will run me more than a used 1000/1100 engine with questionable history. ahh the dilemma to restore or to upgrade?

Get a magnet on a flexible shaft and go in from all holes you can. Go under rotor too-should be an openning. keep jiggling crank back and forth, maybe you'll get lucky.
 
thats pretty much what i did but i think its jammed under the chain so disassembly is pretty much only thing left to do
 
The chain guides can be removed as you tear down the top end -sorry
 
i dont mind taking cams off, timing is not a problem, do i need to take the head off or will they come out with just cams removed?
 
On my 82 gs650 i know the front guide can be removed with the cam cover taken off. it kind of pulls out from the top. The rear guide is not so easy. i believe the rear is held in place by a steel rod at the bottom end of the guide. that rod resides in between the top and bottom halves of the crankcase. Its held in place inside of two grooves in the top crankcase half by the bottom crankcase capping off those grooves. I imagine that it would be very similar with your bike.

How about laying the bike over nicely on its left side and wiggling that crank to and fro?
