    can someone please enlighten me on which liquids are which on my 2kr? when facing towards the front of the bike, there is a smaller black pull off cap on the left. on the right, there is a larger, black screw off cap. the liquids on the right smell really funny on my bike, and i wanna replace it but not sure what it is. the left side has nothing in it. thanks!

    I am 90% sure one is brake fluid for the rear brake (it will say dot3 or dot4 on the black screw on cap) and the other is the overflow for your radiator fluid. Experts please correct me if I am wrong but thats what it is on my 3ln3

    The screw off lid behind the foot brake lever is the rear brake fluid master cylinder - Use DOT 4 brake fluid - Do not use Dot 3 as it is incompatible with DOT4.

    On my 2KR the radiator overflow bottle was under the rear seat on the left hand side. Should be about 1/4 to 1/3 full of coolant when the engine is cold.
