Ok. I am trying to get the stator off a 79' YZ250. I got the nut off and the screws out but it will not come off. How do I get this damn thing off. Do I need a special puller tool or something? I am soposed to go out riding tommorrow but I cant without a spark! Help would be greatly appreciated!

Thanks,
Tony

Try spraying a little penetrating oil like PB Blaster, or Liquid Wrench where the stator fits to the cases. It may take a LIGHT tap with a SMALL hammer to help it loosen up.

WAIT before you F**K it up. There is a special puller needed. It is available thru any motorcycle shop. They are listed in most of the aftermarket bike catalogs.

I have been servicing dirt bikes for over 30 years and would not even think of using a universal puller to remove that flywheel. I have had so many in the shop that have been backyard wrecked with a universal puller that it isn't even funny. On a vintage bike it is more of a problem since the replacement parts may no longer be readily available.

You can spend $12.00 on the right tool or chance wrecking a non replaceable item. It's up to the mechanic and owner.

originaldirt, if parts for that bike are hard to come by your not looking hard at all. I am saying the 79 IT250 i had i always used a universial puller. I am not saying your wrong but why not use one if it works. I am only 15 but work on bikes quite a bit and understand that you have been oing it much longer but as long as you take your time the uni puller would work.

I'm glad SOMEONE finally said it. :cool:

Only a FOOL (or a 14 year old) would attempt to pull a flywheel with a universal puller especially on a vintage bike. The correct puller can be found at most dealers. Unless it's an oddball flywheel you should be able to find one for under $10.

Rich Rohrich, 1st off i am 15, and second if you think a 79 is a vintage bike then your wrong (for the most part). A vintage bike is anything older then a 1974. 3rd is that the flywheel will come off with a uni puller as long as you are careful and slow going, and know what you are doing.

Just when I think this couldn't get any more stupid you keep on typing and prove me wrong. :rotfl:

Rich Rohrich, i am just saying its 1974 for the most part. Some might say 1976 but even thats still pushing it.
That's great you know what the racing organizations use to designate vintage.

But this is DRN, and the title to this section specifies 'old' bikes, not a specific year. A dirt bike from 1979 is old.

Did you completely miss the point that the correct tool is only $10 and you risk ruining a rare part by using some other tool?

Oh, that's right, you know what you are doing, so it's OK :rotfl:

Well 2 strokes, maybe you could teach Rich how to properly service a bike with the incorrect tool. I'm impressed that at 15 you know more than people with 30 years experience, you must be genious :bang:
