SOURCE: spark plug locatio on derbi senda 50cc

The spark plug is located at the top of the engine under the tank. It is the rubber plug cap (usually black) located in the middle of the cylinder head that you must pull off to get at the spark plug

Ride safe

Please mark this as very helpful (if it has been!!)

SOURCE: the coolant fluid is leaking from a small hole on the front side of the engine on my 50cc derbi the hole is supposed to be there because it is on other derbi's
