What's the best tool to use as tried a screw in one and it just stripped the threads, is there 1 that goes over the rim to pull it available? What do you guys use please?

I use the threaded one, its a very fine thread and you need to wind the inner bolt right out to get as much of the puller "inside" the flywheel.
If the threads are shot you may have to find a 3 legged puller and grind the fingers down to get behind the wheel. You have to be very careful as its very easy to damage the coils.

Got the threaded 1 in as far as it would go but it just pulled right out after force, the windings brown to red was 109 and the Haynes manual says 270 so need to get the stator out. Will shop tomorrow for a 3 legged puller and see what happens with that, cheers.

Just make sure you haven't made the common mistake of leaving the washer in and trying to remove it because it doesn't work  |

Deffo washer out mate. But it wouldn't go in as far as I would like, there seems to be plenty of threads left to try and get in but it just stops tightening.

They can be a nightmare to get off ! Good luck. Mine was a b*****d to remove too.
You might already know this but . . .
You should "lap" the taper before refitting it too, do this with out the stator fitted as the flywheel will come off the shaft easier during this process, with some fine grinding paste (clean all traces after from crank and flywheel).

Might sound silly but have you got another washer still left in there, I've had that before where some one used two

It was definitely free of any washers, going on everything else it doesn't look like it's ever been off, will try a 3 legged puller tomorrow, cheers.

Yikes! 3 legged puller often (usually?) buggers the Rotor.
Maybe you were lucky.. maybe you weren't.
Once the Rotors threads are ruined/stripped, it's pretty well ready for the dustbin.

Hmm the puller I have looks like right hand thread and it's that that's stripped, so maybe I've the wrong puller?  |

I had one that would only go in a few threads as the flywheel threads were a bit buggered. What I did was get a fine hacksaw blade and cut some slots across the threads of the puller in several places so it acted like a large tap. Then I wound it in and out a few times getting deeper each time until it cleaned up the threads and bottomed out.
ps I thought all the M27x1 were l/h thread.

All the lads are right here, every comment is valid. Sometimes, they can be a cow to remove.
To get your flywheel off - first have a good quality threaded puller (it should be LH thread). There are loads of crap ones, some I've seen are made of alloy. Spray the crank taper with penetrating fluid.
Take your time to get the puller threaded as far as you can. All washers removed. Tighten the centre bolt tight. Tap the centre bolt with a hammer. Tighten and repeat. Get ready for a bang when it lets go! A little heat can help as well.
A three legged puller risks damage to the stator, flywheel and magnets- only use if you have to. I've known 3 legged pullers to crack the flywheel.
If the internal thread is damaged, I would replace the flywheel 
Good luck, HTH

Glad you got it sorted in the end. My top tip for a stuck flywheel is to pour on a kettle of hot water to help get it moving. Has worked twice in the past for me. :-)
