YZ 80E

[Hoony]

the universal one should fit (like the ones on XR75's) it has a large left hand male fine metric thread.
if you undo the retaining nut you can see if there is internal thread "inside the flywheel" where the retaining nut was.

Retaining nut is now undone hoony, and the flywheel doesnt have an internal tread (that is for the bole type pullers right?)

Ill have a look for a universal xr75 type. The ebay special universal one dad has doesnt fit

Steveo247 , ask at any yamaha dealer or most bike shops the yz80 uses the standard yamaha flywheel puller . if you run your finger around the inside of your f/wheel the threads are very fine if covered in dirt or grease its likely you wont feel them .(tooth brush and wd40 )

As Hoony and iainyz has mentioned there should be a fine left hand thread in the centre of the flywheel, xr75 flywhell puller will fit that thread. Peter.

OOps sorry, did read all threads, sounded like the thread thing was well covered, so hey great job  looking forward to the future when the YZ80E is all together 

[steveo247]

Thanks gentlemen! Yes indeed there is threads in there. I had to look 2 or 3 times! the dirt n crap had almost made them invisible.

Will get em cleaned out and see how i go getting it off.

[Hoony]

good luck mate, it looks rusty in there. let us all know how you get on.

This may sound a bit dodge, but I rigged up a piece of coathanger to clean out threads like this. You get an offcut about 200 mm long, bend it in half, then bend the last 5-10mm of each end in the opposite direction, so they oppose each other. Then you sharpen the two ends to a flat with a grinder and you've got something you can tension up so it bites into the threads a bit (by opening up the original loop) and twist around in an awkward spot like this to clean out the threads. It's not as good as tapping the thread obviously but it works.

What other magic can you work using a coat hanger Dr Mainline?  Liberate locked keys from cars?
