    Re: Sudden throttle disengage

    Is it this?

    It's called a "lowering link", but it's not. It simply shortens the shock by relocating the eyelet.

    So how much of your fork is showing above the triple clamp?

    Raising the forks in the triple clamps effectively decrease rake and trail. Rake is the effective steering head angle. On the FZ6 fork angle and steering head angle are one in the same. 25 degrees is already on the "sporty" side of things. As a point of reference, Standard bikes are typically in the range of 25 to 28 degrees, Cruisers are in the range of 30 to 35 degrees, and race bikes are 24-25 degrees. So you can see you really don't want your steering much faster then what Yamaha has already provided. Trail describes the stability of the steering as it relates to the rake. In the range of 100mm (4 inches) is fairly common for a standard and even sport bikes. The FZ6 is 98mm (3.78 inches) so it's once again on the sporty side of things.

    By raising the forks you may have decreased rake (faster steering) and trail (less natural stability). I say "may have" because I don't know what was done to the shock, nor do I (or you) know the sag settings. I guess the point of the post is this; don't change things until you understand the effect of the change. If you don't NEED the suspension lowered (i.e. you can't properly touch the ground) - then don't do it. If you need the suspension lowered, and now you have an unstable steering geometry, than you need to address that through other means, such as a steering damper.

    I would never ride a bike that makes me uncomfortable. Unpredictable handling is #1 on that list.
    I trusted the mechanics working on the bike to make that call when I asked if lowering was possible.
    My understanding is they did a search on Amazon for a lowering kit by the make/model /year and found a match.
    At the time I had to have it to ride the bike well. Since then I've learned other techniques to hold my balance without needing full contact.
    Obviously if I or they (which they should have) understood the possible consequences of lowering the bike, I never would have done it.

    I'm assuming that's the piece

    I can measure the distance above when I get home.

    Describe the triple clamp so I know I am measuring the right length.

    Re: Sudden throttle disengage

    General update:
    SD card has been recovered from the side of the rode at the wreck spot.
    If video is viable I will let you know definite answers to some of the questions I've gotten.
    Also, he noticed an inch sag in the road where I went down, you can't see the sag when riding over it, you simply have to pull over and inspect it.

    The triple clamp connects the fork tubes to the bike. There are two of them, a lower and an upper. If you are looking at the bike from a riding position, the upper triple clamp is the piece of aluminum that the handle bars attach as well as the fork tubes. There is also a large nut in the center. So when you look at the fork tubes, are they protruding above the t-clamp? How high are they protruding?

    I'd estimate it's a little over an inch

    That disc, when turned (with the cables) opens and closes the throttle (and engine RPMs). If it doesn't move with the throttle movement, you have a broke cable (not likely)..

    And your correct about the engine stopping when tipped over. There's a "Tip Over Switch" under the RS pod that kills the engine when you tip / fall over.
    Nothing to re-set, just lift the bike up. If your curious, remove the RS pod, there will be a black rectangular unit that has "UP" printed on it...
    Throttle bodies move well
