I pm'd you the service manual. If you have a more specific question post it up, might help others also. Not that i will necessairily be able to answer it lol.
If you are asking how to adjust the oil flow it is very simple, but, the adjuster bolt is awkward to get at under the air filter and below the carb. A small 10mm spanner and small fingers and away you go ! turn the bolt towards the bar to increase and be careful not to turn to far i.e. as soon as you feel it going tight stop or it will ring out of the thread. Hope this helps ?
