Hi guys. Now that i'm riding a TA200 myself, i came to realise many Phantom riders had their chain, chain stay and wheel extremely dirty and mucky. Even myself, though not as bad, is very dirty too, black oil patches all over the wheel. Recently i decided to clean the chain and the wheel(rim). Mine is quite a shorter version because i did not use a tooth brush, i only used a rag to wipe things off. While doing so, i've made a video as well. It isnt' very clear but at least you can roughly gauge how to do it.
Disclaimer: The jacking up of your bike is to be done at your own discretion. I won't hold any responsibility should any mishap happen. The reason for the jack is that the rear wheel has to be free rolling in order for me to clean it, no point for me to keep pushing the bike forward/backwards while cleaning as that will take ages.
Self tried and tested: Dipping some kerosene on a piece of tissue works ALOT better than using Cif detergent, when removing oil from your rim and surround area. Initially i used Cif, but a had a hard time trying to wash off all the soap and there are still oil patches remaining at some spots.
