In reguards to the air pressure in the forks. It has a max pressure of about 10lbs I find that 7lbs is perfect for what i do which is full on mountain riding. It has to be checked every fortnight cos it does leak out when the bike is not in use (this is normal)The rear should be between 10 and 15lbs depending on weather you are two up or not (lower if two up). !5lbs on the rear when riding solo is great. I way 100kgs so that should give you an idea. In reguards to the oil leak i have had my bike in pieces trying to locate where it´s coming from. I get it after an oil change and have worked out that it is just the oil breather or over flow. Maybe this info will help ya
