not sure where all the spam word came from

 

You must have put in asterisks or something, but it comes up as 1986 Yamaha. Check the engine I'm fairly sure Yamaha cast the size on the cylinder. Though some also have oil capacity cast near the filler cap. There were only 200cc and 225cc Moto 4s that year.

 

figured which model i have . had to order a headlight switch and the switches were different .so i matched up mine to part picture and it is a moto 4 225. i didn't find any markings on cylinder head. thanks for the help
