designed the airbox on the Trophy -#&*@#%$& you.

While the design is wonderfully strong, probably stronger than many entire bikes are made today, I sure hope that engineeer was prompty let go, never to design anything for a motorcycle again.

It is crazy to have to drop the carbs or otherwise go through the gyrations to change out such a routine maintenance item. I bet a lot of Trophy would be running much better if the air cleaner were much easier to change.

In the end, I simply cut off the 4 inside screw mounts on the bottom, and voila, it comes out quite a bit easier without touching the carbs. This modification does not affect airbox sealing since the darn thing is so rigid.

After looking at my old air cleaner I wonder how the bike even ran. It was running perfectly though, clean idle, no stutering or dead spots and getting 45-50mpg with 20/39 sprockets.

All it would have taken the engineering genius was to make the flanges the same as the carbs and this would have been a piece of cake. What was that fool thinking? I know, service dealer revenue!

Thanks for reading, I just had to get this off my chest since now my knees, knuckles and back feel like they've gone though Attila the Hun's welcome party.

Do you have pictures of your mod?

I just cut the back plate in half vertically. I can take the airbox off easily without disturbing the carbs. Loads of people do this - search for air box mod on the yahoo groups Trophy page
