Hi guys:

My wife has a 2013 XL1200C. I've installed V&H slip-ons with quiet baffles, a V&H VO2 intake, and FP3 with the recommended tune downloaded. This thing is running WAY too rich. Black smoke out of the pipes and dropped to 30mpg from around 55mpg.

We're at 5,000 feet here in Albuquerque, but I might add that I have the same exact setup on my Superglide and everything is great.

The first thing we did was reflash the tune in case there was some corruption in the file, but got the same result. I looked into the specifics of the tune on my wife's phone, and under "engine" it says 96 cubic inches.

We'll try auto tune now, but it seems to me that there's something wrong with the original file, considering that it should say 74 inches.

I'll try to call V&H tomorrow, but in the mean time does anyone here have any input on this?

Thanks.

 

I'd say it's the wrong tune...who recommended it?

 

It's the tune that V&H gives you after you load the bike parameters into the ap.

I got on the horn with V&H this afternoon. Worked with Chris, who provided excellent service. For some unknown reason the tune was messed up. Even though it was a XL1200 tune, it still said 96 ci when you looked at the specs.

Chris at V&H tweaked that, and got it straightened out. We just got back from a 30 mile ride part way up the mountain and my wife reports that the bike is running MUCH better, a lot more power through the range and much better driveability. I followed here, and while it still smells slightly rich, the huge clouds of black smoke when accelerating are gone. After she goes through a few tanks of gas we'll decide if we want to auto-tune.
