Throttle hesitation occasionally
OK, I will give a run down of what I have and then get into the problem. I need advice. I have a 2010 RG with V&H Fuel Pack, V&H pipes, and cams done. When I painted my bike, I had a low profile dash installed with a vented pop up gas cap (I thought this was the reason for the gas smell). Now the problem... I was with my Indy the other day and told him that I smell a strong of gas when the bike was parked in the garage for a night or two and the exhaust smell was pretty strong. He pulled my side cover (right side) and noticed that the O2 sensor plugs were disconnected and zip tied together (did not just fall out). He plugged them back in. I dont remember if there was a reason they were disconnected or not, or when it was done. Now the strong gas smell is gone when I park it and the strong exhaust smell is also gone, but now its hesitating sometimes when I am starting from a stop or near stop. The bike is now popping with decelleration occasionally. I havent been able to get in touch with my Indy this weekend and I am not mechanically inclined at all so I need input. Thanks guys

Some tuners are used with the 02 sensors disconnected. The PCV is a good example. You should take a peek at the Vance & Hines website for the Fuel pack installation instructions to see if its the case with the Fuel Pack. Or you can wait for someone here who has installed one to comment. I use the PCV and my 02 sensors are disconnected and tied up as per the instructions. Runs open loop. My PCV with a pre programmed Fuel Moto Map took away my stock lean stumble (hesitation.)

As for the gas smell, I would have to say the tuner was set too rich, and could not accurately be set without the 02 sensors being plugged in, if in fact they are suppose to be? With them plugged in, it sound like it now may be lean. You really need to look at the Fuel Pack installation instructions. Just go to The Vance and Hiness web page. Either way, I would recheck the setting on the Fuel Pack. From what I have heard, no computer or anything is needed. Its set by monitoring lights and pressing the right buttons. That may be an over simplification, but apparently if you can change your own oil, you can set a fuel pack. If I had more time, I'd look it up for you.

Asking the forum to figure out what someone else has done to your bike is like searching for a needle in a haystack.
You need to talk with the person who installed/tuned the bike. If you bought the bike used and already tuned then i'd suggest you take it to a reputable tuner and get it straightened out. Oh, and i'd stay away from the Indy you mentioned - he obviously doesn't have a clue.
