I haven't even purchased one yet. I'm taking it one step at a time. I'm still waiting on the CDI box. And then I'll go from there. I'm gonna try all combinations with the cams.
Do you think the cracked throttle plate would hinder my bike from starting?
A cracked throttle slide is a common problem on the old wr's, that definitely needs to be replaced. When rebuilding it make sure to put the slide plate seal on the right way up, very easy to get wrong. There is an oval cut out at the bottom of the plate that can easily be mistaken for a cut out to clear the top of the throttle slide where the bolt for the needle is.
The oval cut out at the bottom of the slide plate needs to be at the bottom of the carb.
