Thank you for all your help guys, I will get this last day shift out the way today and have a go at the rotor nut and rotor pulling tomorrow. Firstly using the in gear rear/brake method (didn,t fancy using heat). I really appreciate the help

rotor removal
When you are loosening the bolt you could hit the sosket bar square on to the crank and it will shock it loose. use a hide or copper faced mallet. good luck.My bikes 79 GS1000 1085 checked and approved by stator the GSR mascot :eagerness: and 77 GS750 with 850 top end, GS850g, and my eldest sons 78 GS550, youngest sons GS125.

hopefully the previous owner has not forced the nut back on with damaged threads,or cross threaded it while fitting.
usually a good sharp whack with a heavy hammer on a spanner is enough to crack it loose1978 GS1085.

Argh well, the in fifth gear with the rear brake on, with large rachet handle didn't loosen the rotor bolt, bit of a loss of what to try nextLast edited by Guest; 11-19-2012, 12:49 PM.Comment

Hi gs79, sorry my suggestion did not work. Could you not take the bike to a kwickfit or another tyre fitter or garage and ask them to zip it loose with an impact gun ?. If you were closer i would come to your place and bring my compressor and gun. Also national tyres have mobile fitters it might be worth asking what they would charge to undo your bolt.

I will try a few local garages to see if they can help with an impact gun. I did find that even in gear with rear brake on that the rotor rotated slighty. So is it sufficient when using an impact gun just to have the bike in gear with the rear brake applied.Comment

the nut will spin right off with an impact gun,probably just by holding the rotor with your hands.all the spinning torque is directed on the nut so it has less tendency to try and spin the whole motor1978 GS1085.

Brill thanks, Adrian. Just one other question I have purchased a rotor puller which was stated to be for the Suzuki GS1000E 1980 and it is a M16 X1.5 puller approx 4 inches long with a socket square on the end. I have notice that the rotor has some external threads which I would assume are for an extractor, does that mean I have the wrong puller my friend.Comment

i would say you have the wrong puller. my 78 1000 has a long bolt that holds the rotor on and the rotor has internal threads which would require your style of puller.1978 GS1085.

Anybody know where I can purchase a 1980 Suzuki GS1000E flywheel puller believe it is a 35mm x 1.5Comment

All the GS1000 rotors I have here, have both an internal and an external thread. The M16 x 1.5 puller you have should be correct for the internal thread and should do the job simply by inserting it and tightening up - pushing the rotor off the taper.Comment

won't thread in if there is a threaded crank snout sticking out.
80 and up US models are like this.
they need the external pullers...not a pusher(bolt).
ok if the OP has a bolt that hold the rotor on then he can use a pusher or puller.
if the OP has a nut that hold the rotor on he need a puller not a pusher.Last edited by blowerbike; 11-19-2012, 07:55 PM.Comment

Thanks Greg and Blowerbike for your replies, my GS1000 rotor has the retaining bolt so hopefully my newly acquired puller should do the businessComment
