RE: Vance & Hines Big Shots
I think it is a little difficult but I grinded down the end of an allen wrench (I forget the size) and increased the angle just a bit. It works great...used it today in fact.

RE: Vance & Hines Big Shots
I haven't ordered any yet, I'm still looking at some options, but easternperformancecycles has about the best price I've found, They were reccommended on this site by others. I don't really want to put a fuel pak on I was hoping the stock map for SE pipes would work.

How are you ? Throwing out that “in business to make money” card are ya ? ! ! !
Well, I’m here to tell you like it is, not to make the money thing. Either way, I’m on the phones and working the e-mails.
So, regarding the EFI motors: When you alter the intake or the exhaust components, the Air/Fuel Ratio (AFR) is affected. Any change, even if it’s the baffles, will change the air flow in your motor, as a result, the AFR is going to change. Rich mixture wastes fuel and blackens up your pipes. A Lean mixture burns up the motor, yet you get very good mileage. Lean is bad. Opening up your system’s air flow will allow more air; therefore a Lean condition will exist. On the EFI, addressing the AFR comes via the Re-mapping of the ECU from the dealer or by the FuelPak – in our conversation.
The Harley burn on the ECU increases the fuel by a preset percentage across the whole RPM band. This percentage is good for some RPMs and not so good in others. We have found that there are some RPM ranges where fuel should be reduced rather than increased. The result, is a “bandage” that doesn’t fix the problem.
The fix, is better achieved with the FuelPak. FuelPak regulates the signal from the ECU going to the injectors. FuelPak regulates the opening and closing of the injectors for the proper AFR for your exact bike, your exhaust system & baffles, and your ECU chip level. This is all derived through Dyno Testing here on site, with the same specs you have on your bike.
Slip ons change the air flow; you will need to address the fuel management to be sure not to burn up your motor. So, we recommend that you get a FuelPak when changing your exhaust.
Does this make sense ?

RE: Vance & Hines Big Shots
I just put them on yesterday. I'm going to change the plugs and watch them closely, over the next while. The guy at the shop told me that the stock stage 1 map should work. I'm thinking he just didn't have anything else to offer. Thanks for the letter from Vance & Hines.
