i have a little raptor 50 and i've seen some of the posts previously on this subject but i havent had any luck. i got a service manual and checked step by step and everything lead to the cdi. coil has proper resistance just when bike is turned on i have no power to coil? is there any additional things i should check. the rear switch seems to work and so does the run switch on the handle bar.

 

This may not be the problem but if it is it's very frustrating to find out after doing everything else...check your wire connections to make sure they are not lose in the plugs.
