How much of the gas tank has to be pulled in order to get to the air filter. Will I have to totally remove the tank .
From what I see there is a top bolt and a lower bolt by the seat. What is under there that I will have to disconnect?

A manual is your friend.

All of it. (But first the seat)

Yep.

Petcock, vent line, fuel line, tank sending unit. The petcock screw is JIS, and soft. Put the petcock back in straight, it will go in crooked but that's not so good.
The less gas in the tank when you move it the better, but a couple gallons is not a big deal. Avoid dropping it, and don't put it where you are walking or dropping tools.
A 2 X 4 on end is the perfect spacer to work underneath with both hands. A headband LED lite is good too.
Take care the air box gasket is not missed and put back correctly.
They were afraid the air box top would go missing, so they used 8-27 screws or so.

You're gonna have to yank the tank. Make sure it's close to empty and take out the Philips screw from the petcock and remove the shutoff stem first. There are a couple hoses that are easier to get back on with long needle nose pliers or long hemostats. And don't forget the fuel gauge plug in wire on the Interstate, I've dang near pulled that baby right off!

depends on your strength if the tank needs to be empty or not. I've done full interstate tank with no problem.
air filter lasts much, much longer than the 12k listed by honda. I done an airflow test on a new oem and one with 24k on it. zero difference in airflow. more miles on a a filter actually provide cleaner air to the engine. when u are blowing black smoke and performance is way down then its time to change the filter.

The more times you take the tank off the easier it gets. Just don't forget that secret screw to disconnect the fuel switch from the fuel valve

Knowing that info, what mileage are you swapping out the filter at? |

Wait, are you saying you change the filter with the tank in place and just a 4" clearance to work in? It sounds like more hassle than just removing the tank, but maybe I'll try it next time. A manual is your friend.

Knowing that info, what mileage are you swapping out the filter at? re-testing this summer over 30k now. still runs the same. I have a spare airbox. I hook up leaf blower to inlet seal all outlets except one and put a flow meter at the one. one of many out there not changing air filters at 12k. per many used oil analysis results changing air filter too often actually allows more dirt in. https://bobistheoilguy.com/forums/ubbthreads.php/topics/4543992/100K_miles_air_filter_change |

No, what he's saying is when you go to hook back up the lines, just have the tank lifted a little. |

That's what i do. Slide the tank over to the left a little and prop it up. |

You have to lift the tank a little both to unhook the underneath lines/wires, and to hook back up the underneath lines/wires. That 3.5" is all the stretch you can get out of the gas line (and longer gas lines, and those quick disconnect kits, have mostly been shown to droop and cause fuel flow problems).
Even Houdini could not change the air filter with the tank up only 3.5" (a 2 X 4 is neither 2" or 4")
98Valk, I'm glad to hear that OE filters can go longer than recommended. Anyone who has done this job will note that most all the dirt on the air filter is located on the rear 1/3 of it, nearest the intake. It seems to me the forward 2/3's of it would continue to work, even if the back third was a bit clogged.
Air filters can be tapped out of some dirt, and blown out from the back side with a compressor. I think most of us think that having gone through the trouble of pulling the tank, we might as well put a new one in because while pulling the tank isn't that hard, it's not that much fun either, and the longer we can wait until doing it again, the better.
I don't miss Vtwins at all, but I sure miss the one bolt, two minute air filter change.

Change the air filter once every quarter million miles is enough. Honda did a good job of designing the air intake to the air box, particles pretty much have to do a 180 to enter the intake. BTH, couldnt detect any difference......same as changing the plugs at 100K, makes no difference........cept it relieves the guilt of thinking you are mistreating the old gal....  |

If you can (I don't see how) change the air filter without removing the tank then how could you ever clean everything under there.   Cleaning is part of maintaining. |

You are definitely not talking about the Suzuki Intruder 800's and 1400's! |

Changed mine 3 years ago, not that hard. However, Big BF was here in the Fall and did some intake manifold work. Asked him while here to change the air filter and tune it up. When he took off the old one, it was completely covered with mouse crap and a nest! I didn't see that one coming at all! I think I'll just change mine out every 2 years at this point to be safe!
