got it back from rcr. injector block off, port work, head milled, and 39mmpwk. no spark. must be cdi. anyone have any tips on checking this stuff. thanks.

 

You have to check the coil , plug cap , and pulse coil
( under the fly wheel ) if they meter in range it could be the CDI
but you cant test it so every other conponent has to be ruled out .
I had trouble with mine intermittently and found a poor connection
between the coil wire and cap so to be safe I replaced the coil
and wire , they come together . Latter that night I walked home .
I spoke to Rick Ritter and he suggested changing the pulse coil
Like any coil they can open or fail when hot and close and work
again when cool . I also spoke to a dealer and he told me they
had never sold a CDI , so i listened to Mr Ritter and he was
right . I you need info how to test your ignition let me know .

 

2 days later while looking at electrical map figured out wires to cdi were mounted on wrong tabs. ol switcheroo and fired right up.
