What flat spot?
Ditto on the increased vibration with a sports exhaust system.
Fingers crossed on the duty. Buggers got me for it.

Been running the XIED`s on setting 7 for a long time, no complaints, But what if !! So moved them to setting 8 put a few tanks of fuel through the bike.
The bike runs strong on setting 8 but suspect it is running a little richer than needed. Hooked up the Innovate dual channel LM2 and went for a ride today.
On setting 8 it is averaging around an Air Fuel Ratio of approx 13 to 1.
So back to setting 7.
Graph recorded AFR`s for approx 15 secs at 40, 50,60 & 70 mph.

According to the thread on adventure rider, there was a small issue getting them to work correctly with the very latest LC's.
Something discovered by someone in the States who wasn't able to ride during the winter months and was playing with his computer.
I believe they've corrected the problem, but want to make sure things are ok with a bit of testing.
Think we're talking 2016-17 models. Just shows how manufacturers are having to tighten things up.
Good to know that Nightrider can respond quickly and I would imagine that's why the delay.

Bugger - 8 day manufacturing delay
Comberjohn is correct, it's a problem on very late model watercooled bikes, that are cold-soaked, after first startup. Nightrider is sending me replacement units with new code which I'll check and some others will test too. It may be that they could release the current productions units to you, what year is your bike? Also, who did you order from, Nightrider or BeemerBoneyard?
So you think that the Standard Exhaust System and Air Filter, complete with the AF's is the way to go then?
I have Akro Headers, K&N Filter and Stock End Can with AF's but was thinking I might go back to Stock all round (except for the AF's that is...I'm keeping them on)..
Hi Roger - I've no problem waiting for the latest model - just excited to try them!
My bike is a 2012 GSA, I ordered from Nightrider.
Cheers
Matt
Well, in the spirit of full disclosure...I did like my decat headers because the bike was definitely more punchy. However it was also a lot noisier and Mrs Oldnfat was complaining ( we tour a fair bit). So...went back to stock headers and the bike was smoother...a few days later the AF units were added and after a few hundred miles the bike was much smoother AND faster IMO than the decat bike. I also think low down torque is better on the stock headers (but pretty subjective view) result all round.

Agree with oldnfat, smooth and punchy with the stock system and the AF XiED units. But some may disagree...
If you want to have a sport system and be an anti-social git, it's a free country! I like long runs and found the extra noise tiresome after a while.
I would be inclined to consider putting the stock air filter back in. Seem to remember Geoff at Hilltop didn't think K&N's and similar, were a big help.

While I wait for my units to arrive, anything I should know about installation (2012 GSA)?
Does the tank have to be removed? - Never removed the tank on this bike (had plenty of practice on my 1100 though) - looks like I might have to buy a Haynes or some such...

More than likely Matt,
Can you access the Lambda connectors without removing the tank?
Just be mindful that really you want to conceal these units somewhere safe though they should be splash proof.
They have an earth connection that isnt that long about 200-250mm ish that will need fixing to somewhere. On the my 1150 the XIED lives where the ABS unit used to be.

You dont need to remove the tank, the lambda connectors are underneath the cylinder heads, you need to remove the plastic protective covers (3 bolts). I installed mine one either side of the airbox affixed with stickybacked velcro. You just then need to run the earth wires to the negative terminal of the battery.
The Noise is far from being Anti Social although I don't have a Full Sports System, just the Headers as previously stated.
I certainly don't find it irritating even after a decent Run and I've yet to frighten any of the Horses who routinely frequent the Back Roads around where I live, so I'm guessing that no-one else finds it too bad either.
I'm more interested in Peoples' Experiences regarding the Running of the Bike with these various Combinations installed.

Like I said, it's a free country.
I think most people end up with a remap or AF XiED's, after trying booster plugs, exhausts, filters, etc.
De-cat headers seem to give a slight boost at the higher end of the revs, although my OPINION is that there may be a reduction in the mid range.
With silencers, I think much of it is in the mind.
A German magazine tested all available aftermarket silencers at the time on a TC and dyno'd them rather than using opinions.
The vast majority, and there were plenty, actually reduced power, despite being louder. A couple of the top end ones like Akro, gave the same as stock. Only two improved the power output by two or three bhp and they were seriously LOUD.
Their conclusion was that BMW had produced a system that gave the best power with a modest noise.
By the way, they did a video of the tests to allow people to hear the silencers and just about all of them had that hesitation moving off, which to some of us, is but a memory.
The stock ECU with or without AF XiED units, will quickly adapt to changes to headers and silencers. I believe that I read that Geoff in Hilltop felt that to change the air filter as well, might be a step too far in terms of fueling.
I think many of us feel that once the fueling is sorted out by whatever method, what's the point of assaulting your eardrums by using a louder exhaust when there's no real advantage?
For me, the TC standard exhaust, especially without the flappy valve is noisy enough. It sounds sporty to me and I don't care about impressing anyone else.
