Recently purchased a brand new 2006 SR50 Factory Ditech (injected). The spark plug that is installed in this scooter is a NGK-R ZMR7AP .
I however would like to replace the current plug with an Iridium type from either Denso or NGK.
Have not been able to find any specs on the currently installed plug, NGK was of no help, said it was "to new of a plug to cross reference". Imagine that.
The Use+Maintenance book that came with the scoot specifies that the standard plug for the IE 50 is a NGK-R CPR8E and as an alternative NGK-R ZMR7AP (recommended) / CR8EKB / CR7EKB.
What's the deal here? What is the correct plug I should be using? Why do I have the NGK-R ZMR7AP installed?
Can I use either the CR8EKB or CR7EKB???
Is the spark plug gap 0.035" (0.9 mm) correct???
Any info would be of great help!!!
