    Shiny!!
    More stoppy is a good thing. I like drum brakes just fine, but more stoppy gets really expensive with drums (eve moreso when the drum is part of the wheel casting).

    Nice bike !

    I dont think your disk drilling pattern is optimal though, the holes aligned in radial rows like this may lead more easily to straight cracks.

    They are Kawasaki discs. I didn't drill them. It's the same drilling pattern that Kawasaki used during the late 70's and early 80's. I liked them better than solid discs or the swoop pattern. Good point though.

    More of a myth than a point. Steel and iron are very tolerant of holes. Cracking is usually caused by casting imperfections that grow over time.

    Very funny...one hole is a thing, a row of holes with the last one close to the edge is somethiing else. I can envision that the distance between the last hole and the edge of the disk may make a big difference, though.

    These rotors are scientifically drilled.
    +1. Very professionally done.

    Now that I see better pics, I have to agree that the drilling pattern is a lot better than I thought first. The distance betwwen the outer holes and the edge of the disk is obviously appropriate.

    I finally rode it today. Very different, very responsive and comfortable ride. After some adjustments to the suspension it stops.....now! No skidding, no wobble, no fade.

    Bike looks gorgeous, how do you like the RFY shocks? I have a pair on order for my XJ550R.

    I, like most, was attracted to the RFY shocks cause they look cool and they are reasonably priced.
    So here my take on them:
    > Satisfactory design and materials.
    > Unsatisfactory or incomplete assembly and packaging of product.
    > No product literature, nothing.
    Bottom line is they come with little or no shock oil (different from fork oil). Air pressure is incorrect or there is none. (75-140PSI)
    So carefully take them apart, put in new quality oil, reassemble,and equally charge with nitrogen or air. After you have completed this small task you actually have some decent functioning shocks that perform adequately for the riding most people do.

    I didn't even know they could be taken apart.
