anyone ever mess with the air fuel ratio on the fuelpaks. my bikes setting is om 0. it always seems to cut out at a quarter throttle cruising in any gear. my quad used to do the same but all i did was adjust the air mix screws. im just trying to get ideas. Thanks

 

Did you follow the V&H chart for all the settings, or did you get the bike with FuelPak already set up? When I did mine, there was about 20 different codes to set and it was based upon having high flow air intake and high flow exhaust. It worked great for me. My buddy called out each code setting, I set them, we did a double check and then I was good to go. Never had to revisit a specific code and reset.

 

You might have to send it to v and h and have them up date the fuelpak my 06 deuce had one on it when I bought it and I had to send it in to get the updates send it to them they update it for I think 35 bucks

 

If you've setup your fuelpak correctly, entering the correct values for each parameter and still having issues, call V&H tech support. They will provide recommended adjustments.

 

Thanks for the replies. I did buy the bike with fuelpak already installed. I contacted vance and hines and they gave me the numbers I needed to input. i thought about dyno tuning from the dealer but I though about messing with the air fuel setting my self first, because on the website instructions said you may have to mess with the air fuel setting. Just thought i would get on here and see if anyone has messed with it and had any luck.
