i would be gratefull if anyone could tell me how long it takes to fit a new stator to an 04 250?also is it hard to do or not?thanks.

Should be an easy job.

You just need to pull the flywheel.

Is Beta the one that you can use a universal puller (like a steering wheel puller) on?

If you don't have a torque wrench, mark the nut and shaft before you disassemble, so you get it back on to factory spec.

You'll also need a way to hold the flywheel while you R&R the nut.

I usually improvise a tool, but I suppose you could put the bike in gear and hold the brake pedal.

The Beta owners will be able to help you more with the specifics of the job, but if you can change a tire and your wheel bearings, you can change a stator.

Just changed one this week, and as charliechitlins explains it is an easy task. I had to remove the side brace from the frame to feed the wires out and back in but other than that no problem.

A couple of things I would add though

1. Retorquing the flywheel is critical. I was advised that the torque is 14KNm, but I'm not convinced, so as I have access to a pneumatic impact wrench I made sure it was good and tight with loctite on for good measure. This also has the advantage that holding the flywheel (to both remove the nut and retighten it) is a a lot easier

2. Apply sealant around the wire access grommet when you've finished

dont forget to have a good look at the original position of the stator you are removing,so you can replace the new one at the correct timming .easy way is measure the witness marks left by the bolt heads or measure the gap between a bolt head and end of the slot. it makes a of differnce just a few degress either way.

On a SLIGHTLY different note...

if someone was just wanting to check their timing/adjust it??...is there a mark in there, showing you what the factory spec is??

I believe some bikes (Montesa) have a mark to show where the factory spec. timing is set

I believe that the JLI website has an annotated diagram of where the timing should be set.

click on the year or your bike, then 'FAQs' then 'see diagram'

As bob says, there's a diagram on the JLI website

HERE

thanks for the replies. new stator fitted and running perfectly!

Aaaah...running perfectly...and Beta...words that go together...!!!!...thats why we love 'em!
