It is recomended because you are going to adding a lot of air to the AF mix and it is gonna get real lean. A fuel pack is only gonna make the bike run better.

A friend actually did this with a carbed model we ended up replacing both heads and pistons....save up and add more fuel with a Fuelpack.

First, you do NOT need a fuel pak. This is a myth perpetuated by the purveyors of add-on fuel management systems in order to stay in business. Back in the days of carburetors, you had to change jets to compensate for the additional air flow. However, today the stock FI is more than capable of adjusting to a different A/C and/or exhaust, as long as you do no internal engine modifications. This is the entire purpose of the O2 sensors in the headers.

Second, a "Fuel Pak" is V&H specific, and doesn't work well with other exhaust. Yes, you have V&H pipes, but the Fuel Pak really isn't a great option even then.

Third, if you insist on getting an add-on controller, the most cost effective way to go is the Nightrider X14iED at around $100. This works in concert with the stock FI, but tricks it into running at 14.0:1 AFR, rather than the 14.6:1 AFR that HD is required to tune into your bike.

Ummm your way off base with that. The stock FI will NOT adjust that far. He may not need a fuel pack but he will need to do something to keep from burning up his motor............
