What jetting are you running? I haven't had mine dyno'd, but just finished sealing up everything on my 2 inot 1 Supertrapp. I had an issue with whistling coming from the muffler, but fixed that with rtv sealant. I still have the inner pipe with the 2 cones. I just moved the cones farther back in the screen pipe and welded up the holes the adjustable plates used to attach too. It sounds real good, and I have very little decel pop, if any. When it is really hot out I get an ocassional hiccup through the carb when at cruising speed. Will probably change out the intermediate jet, from what I have reading on here.
Not trying to hijack this thread.
Thoses are the numbers I got. I was a little disappointed with the hp number but it pulls good.
The af ratio is nice all the way across.
I do have decel pop so I tried adjusting af idle screw per s&s manual. Still pops. Pulled bowl and have .0295 inter and .074 main. Guessing dyno guy had good af numbers so didn't jet.
Would going up on jets increase hp and help with decel pop even though af graph is good?

Usually rejet with a exhaust change. If you buy the pipes fpr your bike thru big dog they usually come with a .31 intemediate and .76 or .78 main. The jets you listed are the stock jets, but that doesn't mean that they are not right. The next up from the .295 is the .31.
Also not sayin ya need to buy BD pipes.

Might try the .31. you should start at 1 1/2 turns out and go from there. Also might try the .76 main. You can change the main jet later if you want by just removing the bowl drain plug

Should be able to buy them individually from your dealer or a Harley shop

You will like the 585 in your 08 up from the 546 that's in there. :2thumbs:

guys, good thread on cams & all that goes with them.
just thinking, what cam came with an early 07 k9?
have s&s tops with roller rockers & red paint springs!
s&s 585 sounds good

07 K9 should be a 569
I'm not 100% sure but if you have the red stripe springs and roller rockers you should be able to go with the .600 cam
In 08 they went to smaller springs only rated for 585 and stamped rockers and an even smaller cam.
Hope this helps.
Don't take my word for it, ask around.
