If you've eliminated a weak battery as a problem,then sounds like the same symptoms that many have had on the 425,500 machines.325 is similar. You can first check resistance on the white and white/red wires leading to the cdi from the pick up coil. Should be around 97 ohms +/- 20%. If it's in range,a slight "adjustment" towards the flywheel may be needed so that it will have strong spark using the electric starter. Look at this members post from awhile back. no spark to plug when using electric starter - Page 3 - ATVConnection.com ATV Enthusiast Community Also dirt and trash on the face of the pick up coil or flywheel can cause problems on cranking also.
