Schoolboy error on my behalf I didnt see the belly pan. The front pipes look different to mine, but it’s probably the angle of the camera.
nothing to do with the camera, first time I've seen these pipes.

a set of aftermarket pipes on either is always nice to have anyway..
only for the sound or weight, as the originals are VERY good and it's not easy to outperfrom them.

Re: 6v on cable

it's possible you have a high resistance in the wire (bad connectors/...) you can check this by placing both pins somwhere along the wire : it should reed 0V. if you do reed for example 2V, that means there is a resistance between the 2 measuring points. bringing the measuring points closer together...

Re: Standard Fork Set Up ??

you'll have to figure that out for yourself. if you have no clue, stick to what the manual says. if you feel like the front is dancing over bumps, use thicker oil. if you feel it is to uncomfortable , use thinner oil. pre-load only set's the negative suspension travel, and not the stiffness of the s...

Re: Liqui Moly 2T
