For reasons I don't understand, Toyota didn't put them on the truck, even though they put them on their car hoods. Maybe they are trying to increase the perceived longevity of the truck since these air springs are a frequent replacement item. I notice my Honda has a stick too. I suppose a pair of real steel springs like we had for 5 decades is too heavy or more likely too expensive. I know IBM fell in love with those air springs in the 70-80s and we used to order them by the case. In regular daily use, they don't last very long at all. Some sizes seem to last longer than others. The long ones on hatch back glass were the worst. |

I've got about 13,000 miles on the truck now, after 13 months, and I'm averaging about 23 MPG for the kind of driving I do around here. I've seen 27 MPG on the interstate if I cruise between 65 and 70. Yeah, but I'll bet you've really souped up that Ducati, no? |

1:27 PMMr. Luddite
- show quoted text - Do you really think K&N air filters make a difference? I've tried them on two different vehicles, one with a carb and one that was fuel injected. Other than being a bit louder under full throttle, I didn't see any performance difference. Isn't it true that a stock air filter is designed to pass the maximum amount of air that the intake can handle? If so, of what benefit is a K&N? They may be capable of more air passing through them under test conditions but if the intake only demands what a stock filter can handle, what's the point? ...... Richard, I believe the KN is made for more extreme measures like dirt racing. Possibly giving better filtration but also more air flow while half clogged compared to OE when new... |

- show quoted text - I don't know if the K&Ns pass more air or not. With the three changes I made to my bike it accelerated much faster. I do know that I can dismount, clean, oil, and replace the K&Ns in about a half hour. The stock air filter would take at least an hour just to get to it...buried under the gas tank between frame members with tubes going everywhere. Here's what the stock filter looks like: https://www.harpermoto.com/images/pl...air-filter.jpg Here's a pic showing how it's mounted, but you have to look very closely. It's under the top center frame member, between the two side frame members, snuggled down between the two cylinders. http://image.wikifoundry.com/image/1...3686/GW448H336 ---- That's one thing I liked about my old ambassador. It had a simple paper element in a tin box full of vents. Changing the filter was a snap. That was then and this is now... |

Oh yes I'm sure it would. I'm limited in mine to what I can do. Seeing mine is electronic fuel injected, anout the only things available is through Harpers, there's some "performance" mufflers. And also available is a $300.00 computer box, and that's about it.. http://www.magnumtuning.com/en/detai...zi/jackal-1100 http://www.magnumtuning.com/en/detai...zi/jackal-1100 https://store.58cycle.com/product_p/...FRYbgQodK0oD8g Do you really think K&N air filters make a difference?

However, I was curious and ran across this explanation in a motorcycle forum. Guy seems to know what he's talking about: "Several years ago a bunch of BMW motorcycle enthusiasts decided to test the claims. They dyno tested several bikes with factory air filters, K&N filters, and NO filter, and made several runs. There was exactly zero measurable power increase. The claims tend to work like this: -Factory air filter produces 1.5" H2O pressure drop. -Wonder filter produces only 0.5" H2O pressure drop. Wonder filter is 300% better!!! This ignores the fact that atmospheric pressure is about 384"H2O. Therefore a 1.5" pressure drop represents, at most, a 0.3% power loss. If the improvement were directly proportional to pressure, then the wonder filter might produce a 0.2% power increase, which is completely buried in the noise of temperature variations and barometric pressure changes. But this is not the case. Mass flow varies as the square root of pressure drop, so that difference in pressure allows only 0.1% more mass flow. The actual difference is even less than that though. Because the filter is only part of the total pressure drop between open atmosphere and the inside of the cylinders. Most of the drop is still going to be getting past the intake valve(s). Tuned intakes can mitigate this over narrow rpm ranges, and this is of course where peak torque is measured, so really sensitive measurements may pick up an improvement in peak torque, but anywere else the pressure loss across the filter is meaningless. |

I've not been stopped for noise, although competition pipes are not street legal. They're not as loud as many of the Harleys running around. Harley has been putting a catalytic converter on their bikes since 2010. (2009 in California). They also had them in some models a few years before that as well. No smog inspection on bikes in MA but I think in some states like CA, there is. Actually, MA did away with the tailpipe emission test for all vehicles since 2008 as long as the vehicle has the OBD readout capability. The computer just checks for recorded faults. |
