125-200cc 125 no spark

I have 2012 wr125 and this weekend the bike stopped running after a little checking I have no spark. What do thick would do this in the middle of a race. Also if the bike sites for a day it will crank for a second then no spark.

fouled plug?

Clean ground connection under tank my bike at 4 hrs looked like the ground connection had been in the ocean for ten yrs

Had the trigger on the stator go bad few weeks ago. It cracked and shot the spark to the flywheel instead of the cdi

Check for cracks around the coil and ground. Related to the bad frames!!! We had ours crack and drop spark too.

I don't think the new frame has that problem?

I may have comp wr ign for sale if my cr ignition works out in race on sunday juat took it off tonight

I thought I read they didn't actually fix them with changes and gusseting till 2013??? I'd still take a look there anyway. Ours had a hairline crack interrupting spark.

Found the problem at the ecu . The white wire was broke at the connector

if it's got ducati ignition it is suspect.check quality of spark.mine was erratic
