  1. A friend of mine made this great fall mix and thought I'm not usually a big hip hop fan I find it very relaxing and a good listen. Give it a spin if you need some background music.
  2. Interesting analysis given what is known so far. Fun for discussion at least: http://www.cycleworld.com/2014/09/09/kawasaki-ninja-h2-supercharged-superbike-technical-analysis-and-insights-by-kevin-cameron/
  3. These are just copy-pasted from the kawasaki jet ski specs on the 310 series.
  4. Nice refit/weld on the kegs, I know my buddy will be happy for sure!
  5. Guessing a middleweight 700-900cc supercharged triple from the audio, not an expert but I did stay at a Holiday Inn express.
  6. http://www.vadengmpp.com/owners-manual/chevrolet/2005-Chevrolet-Impala.pdf sections 3-14 through 3-16 may be helpful. Specifically on 3-16 it sounds like the automatic system is only engaged if the manual exterior lamp control knob is set to off. Therefore it sounds like you can set the control knob to parking lights which will only illuminate (parking lamps, taillamps, license plate lamps, and instrument panel lights)
  7. Thanks guys, it really is an excellent firearm, I'm just in a similar boat as you Casper with time and don't like to collect things. This thing was built to shoot and I hate to see it laying around. Cheers.
  8. Selling my P220 Match Elite, haven't used it in a while and need to make some room for other fun. Will come with original case, original 2 stainless mags, Crossbreed Supertuck, and the ammo shown (20 rounds of Hornady TAP .45ACP 230gr TAP +P ,and 16 rounds of Hornady .45ACP 230gr XTP +P) Description from Sig: The SIG SAUER® P220® defines accuracy – and reliability – in a .45ACP. But many SIG shooters have asked for a P220 with a longer slide, one that would compete head-to-head with other five inch barreled 45's. The result? The first P220 Match prototype went to our testing range where it shot an eight-round group measuring 0.64” at 20 yards. Our engineers after extensive review concluded that this was a good starting point. The P220 Match Elite adds the most sought after features to the P220 Match - beavertail stainless frame, front strap checkering, adjustable target sights, SIG's innovative Short Reset Trigger (a DA/SA trigger system with a 60% reduction in trigger reset) and black anodize aluminum grips. Face-to-face sale preferred. $1050
  9. The problem is I don't think you do understand the math. The equations have stood the test of time because they work, at least to a first order approximation(with exceptions for "sticky" surfaces and a few others). Any non-standard contribution is likely to be very small in comparison to the magnitude of the major factors at play. I'm also not going to bother trying to argue with you, but in the phone book situation if you don't understand how an increase by two orders of magnitude of interacting surfaces in addition to a normal force which now scales as you pull harder on the books (think about the angles each page is at with respect to the pulling forces) can explain the "impressiveness" of the trick, then I'm out.
  10. I want to thank all of you again for continuing to do this year after year. As a 4th year rider in Pelotonia, I enjoy seeing the MC support along the way, and knowing many of them are members of this forum makes it even better. I fortunately haven't needed any assistance yet, but thank you nonetheless for volunteering your weekend to supporting this cause. Cheers!
  11. I'm not sure it's possible to have a valid driver's license AND a Motorcycle-only license. That being said, the endorsement is the logical choice anyway. Endorsement means you'd only need to have one card, gets automatically renewed each time you get a new license, and would probably be cheaper since they only print one card vs. two.
  12. Let's be clear, you haven't proven that it applies in even one case.
  13. Can always pm attackpainter or one of the other guys on here for an estimate on getting it re-painted to match. Worth a shot
  14. I agree here, I don't understand what complexities are making contact surface area suddenly matter. Magley, could you please provide some sources to enlighten us? Not being confrontational, if this is true I would like to know the details. My degree is in physics, so I kindof like these sorts of discussions. And I don't see why if we look at a rolling tire at an instant in time (t -> 1/ infinity) the rules of static friction wouldn't apply. (though I admit there may be some non-trivial contributions due to the elastic properties of our real world materials not matching the ideal incompressible inelastic assumptions for the aforementioned equations.
  15. My understanding is that the effects of tire surface area have more to do with the physical limitations of the materials and ways we build our wheels/tires such as heat dissipation, shear stresses, etc. These theoretical equations assume a perfect friction producing material which does not warp, break down, stress etc. under the effects of acceleration. Also likely to include effects mentioned above such as ability to handle imperfections. Both the road and the wheel/tire would have to be flawless, indestructible, incompressible materials to make the above equations apply.
  16. As mentioned above, the best answer is that far more factors play into cornering speed/grip. Regarding effects of mass, the mass of the bike plays competing roles in cornering. As mentioned above, the force of friction Ff = uN, where N = mg . So we have an equation for the maximum amount of friction force that can be developed which depends on the coefficient of friction u, the mass of the bike m, and the acceleration due to gravity g. This suggests that for a stationery motorcycle (if you locked both wheels so they couldn't spin), increased mass would in fact provide a stronger force of friction. However, lets consider the cases of straight line and circular acceleration. For a straight line, the fastest you could accelerate would be if the force of acceleration were equal to the maximum force provided by the tire. F=ma for force of acceleration, Ff=umg from above, setting these forces to be equal Ff=F substituting for our other equations we get ma=umg And we can immediately see that mass can be canceled out of both sides and we get a=ug. The maximum acceleration we can get is only dependent on the effect of gravity and the coefficient of friction, which is a property of the rubber in the tire. Similarly, the centripetal force required to drive in a circle is given by F=mv^2 / r where m is mass, v is the velocity or speed of the vehicle and r is the radius of the corner. Maximum corner speed will be when this force is equal to the maximum amount of friction available, so once again Ff=F Substitute in our equations and we get umg = mv^2 / r Once again, mass cancels out on both sides ug = v^2 / r rearranging for velocity we have v = (ugr)^.5 , or the square root of the product of u, g, and r. This suggests that maximum corner speed is a product of friction coefficient, gravity, and corner radius alone. The big picture here is that while increased mass does increase available friction force, it also decreases the amount you can accelerate (either in a straight line or around a circle), and these effects are both of the the same magnitude (strength) but counter each other. That being said, there are a great deal many more factors in the real world that come into play such as lean angle, corner banking, suspension dynamics, and several others that complicate the issue, as well as the physical constraints of the materials in the tire. Not sure this was helpful, but that's what I've got. And as mentioned above, surface area of contact (contact patch) does not affect the force of friction.
  17. I bought my vfr with ~28.5k on it this spring and it now has almost 34k. I wouldn't worry about almost 40k unless the bikes have known issues. Modern motorcycle engines can last easily as long as car engines given proper maintenance and if the owner doesn't beat the piss out of them. Offer 1800 given the miles and enjoy it.
  18. These Delkevics? I've been considering them but need a good firsthand review from someone I trust Did you install them yourself?
  19. It's like you didn't even bother to read his whole review. HM had shitty service, end of story. When you take a bike in for a repair estimate, you assume it will be properly inspected and written up. Anything else is just plain lazy, and speaks to the level of service said dealer provides.
  20. PM danballa on here if you have questions about setting one up for touring. His busa had a pretty awesome givi setup which could carry tons. http://ohioriders.net/index.php?/user/10590-danballa/
