First of all, welcome to the forum. To answer your question, you should rejet.
Here is Dinqua's jetting calculator which is a good place to start with jetting. This is not the absolute answer but as I said, it's a place to start with jetting. The BEST way is to jet and dynorun. Or the seat of your pants dyno can help.

No damage right away. You've got a some time but don't wait for months to go by, you know.
Do a search on this topic and you can learn more about the topic....quick ways to rejet by dropping just the bowls, how to read your plugs by looking at the color, etc...

sorry still really confused ive had so many contradictive advice (not on here)dinqua's jetting guide says 130 main 42 pilot jenks bolts said 135 main 42 pilot 1 shim
free flow air box, some guy who sold jenks bolts the company said 120 and maybe 1 shim but get it on a rolling road, and then some chap who used to tune triumphs and worked for triumph said you can't chop out the stock pipes like that your going to do more damage with no back pressure
I am at my wits end please help

look you dont need back pressure. my america will leave a black mark down the street how ever long you want. All i did was install the unifilter, remove the snorkel, install 130 mains, shim the needle .9 mm, turned out the jet screw to 2 1/2 turns out from closed, and remove the silencers.
I installed some 18" turn downs. I beat a 1200 sportster off the line and he could never make the distance back threw all 5. I stayed ahead of him 1/2 a bike length. I know you dont want to hurt your bike but trying to beat out the baffles or punch an over sized hole in them is way out there. I put 22" x 3 1/2" slash cuts on my friends bike $105 for both. at a muffle shop and my 18" turn downs $40. For the price of performance replacements you can go to a custom exhaust shop and have some thing completely unique built.

Welcome to the "back art" of tuning...your location, elevation, will effect the jetting...so I am at sea level so my jetting would be different than when I lived in CO. Start with dinga jetting...then read up on tuning and change one thing at a time...say up/down one main jet size...see how it runs....or...take it to a dyno tuner who will tune it on the dyno....

Yes this is true, you will have to tune the bike afterwards. However thats not to difficult either if your local triumph dealer is cool. The tech will tell you what he has been doing to get the best results. Your bike may differ to an extent, but its a good way to start. I also live at sea level here in texas, down on the gulf. you dont have to dyno one just ride it. If you have been riding long and understand mechanics of it all you'll befine.

My exhaust does not look like the posted photos: 2006 Bonneville America
They are slash cut and the inner (smaller) pipe is about 3" inward.
Would the same baffle removal method apply?
