Bonneville America Forums Forums Technical Forums Performance Mods Jetting question

So for some reason I can't access the newest jetting calculator, and was hoping to get some advise from the collective genius of this site.

I've removed the airbox from my '04 BA and replaced with amal-style reproduction filters onto the carbs, an idea I got (stole) from Earle. I am still running the stock exhaust and need to re-jet my carb. I may or may not remove some baffles later, but for not I am gonna keep it stock, unless someone can convince me otherwise.

From what I have been able to find, I *believe* I will need 145 main jets. I have also gotten mixed info on wether or not I should change my pilots and needles as well. I was planning to get a couple sizes of mains and pilots to try out, but wasn't planning on replacing the needle.

If anyone out there has the same style setup, please let me know what works. Also, I know there are a bunch of you that have much, much more experience than I do with this sort of thing, so please feel free to leave your suggestions.

Thanks in advance,

Without changing the exhaust you're not going to get a huge increase in air flow so the 145s might be a bit much. I don't have your setup but my experience with open pipes and the stock air box teaches me that both ends have to open up before you can really bump up the mains. You could probably get by with a shim and a mix screw adjustment until you open the pipes.

Which jetting calculator can't you get to? Can you get to this one?

hey friar thanks for that i could never open the other ones either, tried this one and bang on to what i am running.

145 with stock exhaust is going to be too much, even with those changes you won't be far off stock. The shim idea etc might be the best way to go.

Friar - Strange, I was able to follow the link you posted above, but for some reason it wasn't working from my favorites earlier. I had found another link from your site (the one with the calculator over a photo of what I presue to be your bike). Thanks for the new link, I've having trouble w/ any Dinqua sites lately



So do you guys think I should put more thought into removing a baffle, or see how thigs go with a shim in place? I'm getting ready to clean out and rebuld the carb for what I presume to be the first time, so I really want to set it up right w/ the new intake...

Thanks all around!
