Spinning on the crank? What?

Have you bent the lock tab back out of the way?

Stick a 3x2 through the swingarm, get a mate to stand on the rear brake lever. Attack it with cracking bar.

what i did i rammed a huge bit of wood through the back wheel ang got my bro to stamp on the back brake, i then sat on the floor with my feet against the wall and yanked the torque wrench and eventually it came off

It is fecking tight thats for sure.

I snapped 2 breaker bars on the last one I did. I ended up having to take the bike to my local tyre fitters and got them to put a pnuematic impact wrench on it. Even that struggled!

what exactly do i need to remove to fit the new headrace bearings? ive got the bike mechanic coming over shortly to press the front/rear/sprocket carrier and headrace bearings.

Im not entirely sure what needs to be removed from the front so he can press the headrace bearings in

any help appreciated

The complete front end, that is; wheel, mudguard, forks, top and bottom yokes etc. It's not strictly necessary to remove the fairing but that will make access easier.

ive taken the two upper side fairings off and you can easily get to the bolts on the forks i would say.

If i remove the big nut on the top of the yoke would that let the forks drop out?

Look closer.

Remove big nut. Remove top yoke. Then there is adjuster nut underneath. Lots of sundry bits to take off to get them out of the way.

Hang on. Is that an SRAD front end there? If so TAKE NOTE of the dimensions, the stock SV bearings WILL NOT WORK if the top one has been changed to accomodate the GSXR steering stem.
