hi all .got beta evo 250 2010 wound nt start so i did all the usual checks spoke to beta uk they said prob stator.so i sent to west country winding .had a new pickup and stator rewound put them on bike still wont start .the bike sparks once at begining of kick and once at the end of rotation .checked black and white cable going in to cdi its reading 250 oms .i am totally puzzeld can anyone help

Still have original beta kill switch on ?

im not sure but i disconeted completly to make sure

Sounds familiar , after fitting a new stator mine was the kill switch.

think i will speak to lampkins see if they can help .i dont want to just buy parts for sake of it ..its an hard 1

250 Ohms sounds about right for the source (ignition power generating) coil. Check the resistance of the pick up (timing trigger) coil. I would expect it to be 850 to 1300 OHMS.

Rig up an electric drill so you can steadily spin the engine. at about 450 RPM you should get about 20 to 30 volts AC from the source coil and 1.5 to 2 volts AC from the trigger coil.

If all is as above and its not the kill switch try borrowing a known goog CDI and ignition coil.

Check for wire to coil shorting intermittently on frame.

Try spinning the engine in a dark garage and look for stray sparks.

Cheers

i think by getting a third party to repair an oem part many importers would wash thier hands of the problem..

well to be fair an importer told my to do that ..if the parts were made better from start so many people wouldnt have electric problems ..cheers

I totally agree - this will confirm your stator output. Then if you can borrow a CDI and coil, that will confirm the sparking. If that does not work, you have something wrong in the fuel system, crap in the carb, no flow, broken fuel switch.

well after all .i put new stator on and cdi now it is working again .so it was the cdi

Very interesting that the bike would still spark with a bad CDI - perhaps its timing was off or too low power. Glad you got it figured out.

Have you checked the obvious such as fuel flow and spark etc?

pindie, - ya gotta read the thread! He said he fixed it. CDI. :-)
