Advice on general YZF R125 maintenance please

Hello Yamaha Owners I am pleased to join you.

I purchased a YZF R125 2008 model on 23/09/09 when i was 16 privately, i am now 17 and passed my CBT yesterday and am hoping to have my bike on the road tomorrow (I just need TAX).

I need general advice on maintaining my bike please like how to look after the chain, tyres, engine, just everything which must be checked and looked after. I have read the manual but i do not understand it all and do not know if all of it is nesseccary. I would definitely like to know what products to use on the chain to clean and lubricate it. In the manual it says use kerosene to clean, and a suitable O-Ring lubricant, but on the net i have read many times not to use kerosene or petrol and stuff so just what do i use?? and what is a very good lubricant ?

I look forward to hearing from you, and hope to remain active on this forum
