A flywheel puller would be a fine start.

Pics of the flywheel area and it may become apparent what sort of puller is needed.

Not directly helping but have you gotten one of those manufacturer book things?

Fly wheel puller as YC said. I didnt have one when I had to replace mine a month or two ago I used a brake hub puller but it still needed a fair bit of persuasion and 2 pepole to take it off. eventually the shock from a hammer knocking the handle on the puller was enough to loosen it.

is that anything like it?

Need to know what's under that bolt. If there is a thread inside (not the bolt thread in the crank nose, a thread in the flywheel) then you need a bolt to fit it. That will press the crank out of the rotor.

Yea there is a bigger thread in the actual flywheel but cannot find a bolt big enough any where in my workshop, my Dad was on about pulling my rear wheel spindle out of my sv to see if that was big enough, will ask if work have a flywheel remover tool tomorrow.

Depends on the size. Some bikes happen to have a swingarm spindle that's right. SV is M20 fine pitch... picked one up locally for £2.

[yorkie_chris]

the rear axle will also serve this purpose,

Try it.

Get some diesel on hand. Don't be afraid to screw it in as tight as you dare and leave it for a couple of days and see if it will "creep" off

I shall try that thought that the fzr one was too big or small (cant remember) goof job as wheels need to come off soo as they have sold :p

Oh yeah belting the puller as per the archive doesn't always work. You sometimes need to use a mixture of heat/cold/impact/tension/penetrant/patience.

So do I get that kiss next I'm in kent?:lol:

I shall try all of yesterdays suggestions today in fact but not now.

No apparently some neighbors can find the use of impact wrenches at 3am irritating.
