  1. So, Stan (or whoever has his ZXXX now) and Skull: I'm guessing you haven't noticed any serious deterioration in the bearings. Can you give me a rough idea of the mileage you've put on since the swap?

    The biggest problems I've had with those bearings is that, due to exactly the reasons your friend stated, it's difficult (at least for me) to determine how tight I should torque the steering head. As Stan mentioned, I have had some trouble with the front end bearings, but it was the tapered bottom bearing which has already notched. I attribute this to having used one from All-Balls, rather than a better quality thrust bearing. Due to a great many factors, most of them medical, Stan has actually put more miles on my bike than I have, and it's not enough to give you any meaningful data.

    I view my bike as a science project, at this point, and I deliberately do not expect anything other than for it to be temperamental. Stan has had good success with it, so I may come to view it in that light, eventually, as well, but my bike has other issues anyway. :icon_evilgrin:

  2. I've talked to a "bearing guy" and he assures me there is nothing special about the MRC bearing except the price . . . and that is "special" in a Special Olympics kind of way. So I will be going with the bearings instead of the adapter, since the bearing option now costs 1/10th what I thought it would, and I won't have to keep waiting.

    You were third in line anyway. :icon_biggrin:

  3. Do I need to get another torque wrench?

    Probably. 78 lbi is 6.5 lbf. Most lbf torque wrenches aren't particularly accurate that low.

    As for why it was so tight... I'm not sure. Thread locker, maybe? I have no gut instinct as to whether it's a misprint on this.

  4. I'm not sure why I didn't think of this sooner, and it's too late to be useful at this point, but I'm pretty sure I remember the ZX14 neck bearings being the same as the bottom XX neck bearing.

    The od is, but the id is different,,,,,I think.

    I actually think they're the same, but it's been some time since I had both apart to measure.

  5. Assuming that spacing needs to be adjusted to align w/the front sprocket.

    It doesn't need to be adjusted.

    Speaking of which, can the Kwaker rear sprocket be had w/BBird stock # of teeth? New sprocked cost vs speedo healer cost.

    A ZX14 rear sprocket can be obtained with the number of teeth on a stock Blackbird rear sprocket, yes.

  6. Unless you're drag racing, nitrous won't get you what you want. Flowing the heads and a big bore kit won't happen under $1000. A turbo won't happen under $5000. Sell the Blackbird engine, add that money to your $1000 and buy a Hayabusa or ZX14 engine and a Power Commander.
