  1. The clip-ons are more like "helibars" with a 1" or 2" rise as compared to typical sport bike clip ons. If you're able to lane share / filter, the clip-ons are more friendly for that dipping below most car mirrors. Since you have an Tracer, personally I'd go for the "S" model. Get that low(-ish) sportbike feel. The N would feel a bit more like the Tracer and might seem a little redundant IMO.

    * Air flow is much smoother, but the stock windscreen was too short for me. I installed a taller screen from CalSci and the cockpit is now a great place to sit even in foul weather.

    A well designed fairing plus a well designed windscreen makes for a great riding experience!

  3. Haha! I too have "accidentally" bought a motorcycle.

    Years ago, I looked at a Husky SM610. When I got there, it was in rough shape. The owner was a very nice guy and simply didn't know what he had nor what to do with it. He asked, "knowing what you know, how much would you give me?" I said $1500. He countered at $2k, I walked because I was moving out of state in about 6 months and really didn't need another bike to take.

    A few days later he calls me up and says, "$1500 this afternoon, I'll drop it off."

    For reference, at that time a well sorted SM610 was $4 - 5k.

    Some of you on here have amazed me with items you have made with your 3D printer. 

    See this....

    Super cool! Really opens the design freedom.

    So fun story which requires some background, I work with metallic 3D printing (additive manufacturing), specifically titanium alloy(s). We had a part that wasn't adequately fixtured. The residual stresses were so high it was shearing the heads off certified grade 8 bolts. I can't really share a lot of details, but I lost count how many failed.

    I purchased my 2015 fj-09 in July and from then I've put a BMC airfilter in and cut the snorkel half way up in the air intake box. Then replaced the seat, Sargent seat an the rear shock with a K-Tech and cut off the muffler and slipped on a Competition Werkes. Now I've replaced the rotors with Galfer wave and HH Sintered pads front and back. I also put a sump guard on it.

    Next is Andreani fork cartridges and ECU flash.

    You have great taste in mods!

  6. I never worried about damaging the kickstand, but it sure scratches the hell out of my garage floor or driveway. Only reason I don't do it regularly.

    Steel is kind of amazing stuff. It can be very thin but yet still incredibly tough. For cylinders, the stress concentration is distributed around the outside, called a "hoop" stress. Stress only goes down as you go towards the center in a solid cylinder. Therefore, if the outer ring can withstand the stress, no reason to fill the whole thing in.

    Compressor tanks and other pressure vessels are designed by a "leak before failure" criteria. Therefore, the wall thickness has to be much thicker so if a weld failed or puncture occurred, the whole thing wouldn't blow up all at once. Since the kick stand isn't a pressure vessel, it can be a whole lot thinner and still very strong with respect to the weight of the bike.

    That being said, wall thickness certainly helps when dealing with non-axial loads. If you dropped the bike while doing this, in the direction where the kickstand can't just fold, it might bend or break. However, if you execute this maneuver correctly, the reaction forces will be torsion from the spin and axial from the weight of the bike and everything works just fine.

    I'm writing technical reports this week... Can you tell?
