Mille GT air filter - Recs for separate filters, AND how to remove stock one!

[baloo]

89 Mille GT
How in the world does one remove the stock air filter?
From the looks of it, it appears I have to remove gas tank, get wrenches in there, and extract the filter in some contortionist manner!
If so, I need to change to individual stacks or some other filter system that is more easily accessed.

It appear if I went to indivdual filters, I would not longer be using the central air scoop that normally leads to the air box.  Will this change air flow to the carbs, requiring rejetting?

Ach, Imma starting to hate this bike.  First it was access to the dizzy; now this!  Both should be highly accessible because they are periodic maintenance requirements.

Thanks.

 Please keep your air box! These bikes run so much better with the air box intact! YMMV!
Air filter removal is really quite simple. Referring to the drawing at plate A9 of this document, https://www.guzzitek.org/parts_list/gb/1000/ select 1000GT from this list, remove 2 screws #9 jog rear of box back slightly, opening one side is sufficient to remove the filter adapter #6 then the filter, they may come out together. If you can't get enough space one of the boots can be removed from a carb by loosening #2. It really is easier than it sounds. All of this is easier with the tank removed as are many things related to this and many other models / makes of motorcycles. For more difficult procedures see most any of the Guzzi models immediately preceeding this one. This was considered a huge improvement at the time!

I agree with BMC.

It's not as difficult as it looks.  Once you've done it once, it's fairly easy, much easier than making a Mille run correctly without the airbox.

And how often are you planning to replace the filter, anyway?

Brain and NC43  (or is it 1943 BSA???) -- great to see you are both Mille owners!
Thank you for the advice about keeping the original airbox.
I went on line and sure enough, there was a Brit explaining how to get to the filter.  Many more steps than you describe:  remove seat, remove tank, remove front battery hold down holder, remove both 90deg air intakes to carbs, plus remove the 2 airbox screws.  FOR ME, it truly needed ALL THAT CRAP removed before I could FORCE that filter out!  Many expletives and many new adjectives were invented.

Air filter was a mess, so good thing I went thru the trouble.  It might even explain why I am getting mucho backfiring at high rpm (above 5K).
Yah, I doubt that I will ever ride the bike enough to ever have to change the filter again, so, taking both your advice, I will order a stock replacement and be done with it.
Yah, I was worried about two things with changing to individual cone filters:  1) different air flow to the carbs, and 2) worries about jetting.  I just do not have the time to dote on the bike (too many other "doting" car projects needing attention).  I just wanna start it up and ride ride ride whenever.

Thanks again.

Brian,
Also, thanks for those links!

Guzzitek is a great resource! Any manual you want parts, service etc.

My much modified (headlight, fairing, and many other little bits and pieces) Mille GT is the one bike I won't be letting go of anytime soon. At 74 years old it is getting a little heavy and I fear dropping it while pushing it around etc. once underway the weight is mostly unnoticeable.

Brian,
What are those saddle bags?  They look very high capacity.  Are they detachable?
Also the seat:  what kind is it?  From another model bike, or made for the Mille?
thanks.

Saddle bags are Hepco Becker 40 liter bags on Hepco Becker mounts, all still available from.

The seat is a Corbin that is no longer available. Found it on EBay and snapped it up years ago. Patience is your friend when seeking parts for bikes like this .

I've had this bike since 1994.
