Can not break the flywheel nut loose! Gsx1100

[gorbys]

Starter clutch is gone or at least there's something wrong and I need to investigate but I can't get the rotor/flywheel nut loose for the life of me. I have the transmission in top gear, rear brake engaged and still the engine turns when I apply force to the breaker bar. I tried to make a tool to hold the flywheel but damn near lifted the entire bike off the ground instead of breaking it loose. I've tried an impact gun but that didn't help either. Any other tips? Might try to borrow a bigger impact...

yeah a more powerful windy gun normally shifts them.

There are two holes for a special tool to hold the rotor, I made a tool to fit.

 

 

And bought a rotor puller,

 

 

Hope this helps.

 

Cheers Andrew.

I have a holding tool here. In Somerset if that's any help

[Mike711]

Heat it up.

Screw a bolt into a sparkplug hole (M14 x 1.5) to block a piston, If you'r in doubt, do it with 2 pistons.

Then carefully try to undo the bolt. If you still need a lot of force, the try another way...

GSX is different than a GS, isn't it?

 

With a GS you just screw a bolt in as tight as you can get it in, and give it a massive wack with a big hammer

Only know GSX not familiar with GS style.

Although my GSX750 has a bolt and needed a slide hammer to release.

on some gs motors you can remove the flywheel by using the swingarm spindle, you unfasten the bolt into the end of the crank, screw the spindle in to the flywheel till it touches the end of the crank, tighten it as much as you can, then belt it on the end with a hammer and the flywheel will pop off.

no, i didnt believe that too till i did it!

not on the gsx motor though, sadly.

Take clutch cover off and lock clutch and crank gears with a 2p coin , can also be done on starter clutch gear but could break the boss around idler gear
