I have just bought an old kids off road bike, which I think is an Italjet . It has a Motori Minarelli 50 cc engine, with Brevetto stamped on the bottom of the barrel and number x 1578 x is stamped on the cases just under the carb. The carb is a Dellorto SHA 14 9. The exhaust hangs low and exits on the right hand side.
There is a number stamped on the front of the headstock which is: 12248. It looks like a CX50 but is an automatic.
I really need to know what spark plug to put in it. Any help appreciated.
Sorry, can’t work out how to make this a live link, but hopefully you can copy and paste into your browser to access my italjet photos on snapfish. Couldn’t post photos directly on here as file size too big. Have found out that the plug should be an NGK BP 4HS. Thanks.
