Hi giunchi, welcome to the forum, although your English is a little off the mark, I get what you're saying.
Dion, let's just hope that someone comes up with the amount of oil as I can't remember how much we ran in ours.
We made our own dip stick in the form of a T bar. The top of the T was just wide enough to sit across the neck of the filler.
We put the desired amount of oil in then dipped it and marked the stick.
Once you are satisfied that you have the right amount of oil in there, run the motor and mark the dipstick with a HOT mark which will obviously be lower on the stick.
If at anytime you dip the oil when cold and find it below the cold mark, DON'T top it up. Run the motor first and see if after a few minutes running it comes up to the hot mark.
My friend made this mistake once, the oil showed low so he topped it up quite a bit, when he started the bike, the oil came right up to the filler neck and he had to empty some out.
What had happened was the none return valve had stuck and the oil had drained back into the sump, don't make the same mistake Dion.
Sam.
