RM 125 fuel mix ratio + gearbox oil?

Hey just bought a 125 rm 1998 model. My first 2 stroke. I know you guys must have covered this topic a million times so sorry for asking again and i know its down to personal preference but does the type of gearbox oil such as semi or fully synthetic affect the fuel mix ratio? Should i go with fully synthetic and if i do so should i run like 40:1 fuel to oil ratio. Ill be most likely riding trails and im not a very experienced rider. Thanks

No it doesn't matter

Follow the service manual guidlines

32-40:1 is fine

Ok thanks krannie. Gota order a service manual off the net as the owner didnt have one unless any one knows where i can download one for the 98 model?
