motor spins....... no spark till i let off the starter button...
i pulled the plugs and grounded them out ....to check spark, and it clearly is only sparking when i let off the button

any ideas?

Motor needs compression to spark..

IS your Ignition stock or is it modified with a Tuner device?

Max is right.  Put a spare pair of plugs in the heads & then check for spark with the original plugs attached to the plug wires & grounded.
What is the reason you're checking for spark ?

thanks guys
It has a sert tuner..
Last season , it would only start as i let off the button
iv done some further searchin and it seems that lower voltage will do that ...
going out to clean my cables and mabey run a ground to the frame..

If your voltage is low the starter will use about all of it and then there is none left over for the ignition.

How's that for a technical description?

turns out the aftermarket cables i put on last season... the ground had no pigtail for the frame...
hooked up stock ground cable ... she fires ...but i think its time for a new battery

True dat !  Seen it lots of times.  Weak battery will turn the motor, but weak spark
