Hi Guys, Thanks to you lot, I've finally got my 2005 Beta 250 engine built and in,I've had the bearings bore,rings, etc checked, new oil seals, gaskets etc, got a new CDI? (black box) had the stator rewound. When I try to start it, it kicks back really badly but won't start, when I put the stator back I put in the same position there were indents where it had been, I've tried moving it in the same direction as the crank (retard)?still won't start but now it backfires though the exhaust.Please help I'm at my wits end, I've done all this and it's the same as when I started!!!

hi

been there done that...

check all earth points ( on my techno i found that under the wire to frame connectors a white powdery corrosion had formed ) this can cause a bad missfire.

double check that you have lined up the stator properly , while your there check the drift key on the flywheel ( common to snap if your engine backfires and the flywheel is not on seriously tight).

lastly .. where did you get the stator rewound , a certain company in the uk has been doing a very poor job recently to the extent that stators that they have rewound have been so bad on return that they would never work.

I had the stator rewound at West country windings, checked the earths, the only thing I hav'nt changed is the coil/ plug cap, do you think that could be playing up?

in all honesty i think its time for you to contact steve at sales-web@uk-motoplat.com

this sounds like another faulty wound stator to me (your the fourth one i have heard about)

let steve know whats happened and ask him to test the cdi and stator ( you will have to send them to spain but its not a problem and its quite reasonable postage)

the only down side is that its gonna be about

Thanks Neville, Just e-mailed Steve, cheers
