So, yeah, I'm an Oddball . . .

. . . but I want to put the stock pipes back on my 2002 Bonneville. All I know for sure about the mods done by the PO:

--AI removed
--TORs added
--Main Jets changed to 122 or 125's
--No idea on how far out the mixture screws are set

My questions: can I replace the TORs with the stock pipes and leave the larger main jets? What would be the potential problems? And if I end up having to go back to stock 110 jets, how many turns out should the mixture screws be?

Thanks in advance.

You'll run very rich.

That said, do you need stock pipes? PM me.

There is a fine line between "hobby", and "mental illness"

Actually, the PO gave me the stock pipes with the bike--but thanks.

I guess I'm wondering if "very rich" is "too rich?" One dealer/tech told me all the Bonnies come out of dealerships running way too lean--but would the larger jets over-correct that issue?

As you can tell, part of my problem is that I'm just unsure how all the jets and needles and shims work--I've started studying the stickies to educate myself, but I feel like I'm more confused than I was!

I think you are going to be too rich. You need to establish what has been done. The 125 on a 790 motor would suggest exhaust and maybe a free flow filter. Also a lot of people seem to bump up pilot jets to 42. You need to establish whether the snorkel has been removed (L) side panel. If that has been removed might be worth checking the restrictor plate is still there, at the jetting you mentio should be, remove air filter and feel in the airbox. Shims you will need to take off the carb top and see if a shim has been installed.
Standard settings 110 main, 40, pilot, 0 shims, Pilot screw is @2.5 turns.
I think if you revert to standard pipes she will run a bit lamely!

Thanks for the input. If I go ahead with the switch back to stock tune and don't like it, I'll let you guys know so you can say, "I told you so."

And no, I'd better not sell the TORs just yet since it seems I'm going to be so unhappy with the stock pipes!

The Tors are very close to the stock pipes really.. IMHO the are what the stocks shoulda been.. Your gonna open a can of hassle for very little result.

Find a shop that has an exhaust gas analyzer. That will get your carbs spot on and you won't have any doubts.

BTW, you're not so odd. I have the stock pipes with no plans to change. Loud pipes make you tired and irritate your neighbors.
