gs300l spark cuts out at half throttle

[Pigthang]

I have a gs300l I've been working on for the past year or so now, and after a complete carb tune, engine rebuild and much much more I've finally run into another brick wall.

My ignition system took a dump. The bike will idle all day long but as soon as i give it gas, the spark fails on both cylinders.

Is there a test for the ignitor box (CDI Box) and the signal generator?

Also, I would like to actually convert this bike to points to make my life a little bit easier *caugh* I mean cheaper *caugh* haha. If you guys have any good advice about that as well give me a heads up.


Thanks in advance,

Pig

".........The bike will idle all day long but as soon as i give it gas, the spark fails on both cylinders"

How are you determining that the spark is failing (and not something else)? have you checked for loose wires from signal generators to ignitor and from ignitor up to coils? Make sure battery voltage doesn't drop as you give it gas ( i.e..charging problems, short circuit ??)

I have a spark plug testing tool. its basically a spark plug wire extension with a test light in the middle.

i've checked the connections. one of the generator's Ohm rating is reading sporadic when any speed, slightly above idle, is achieved.

I have a new generator plate coming and I'll test that if it doesn't work i'll return it.
