But if we did would that not keep you busy
Not if you're dead... no.
Severely wounded yes... I don't want to be busy anyways. Quiet night is always a good night.
R1200GS is tucked up with FJR1300 Special. So hope they dont get jiggy....

You don't say what your EU4 full akra bike makes !! it would be interesting to see, to compare against EVskij standard bike and if the system makes a substantial gain.
+1
Although to be fair both bikes would need to run on the same Rolling Road on the same day with the same operator to get a fair comparison.
But I would be very interested to see what the Akrapovic Titanium £1300 cost provides in BHP gain, in addition to its weight reduction.
I love significant weight reduction as it can be very effective in all areas... accelleration, braking and handling but that benefit will not show up on a rolling road readout. Titanium exhausts, carbon fibre wheels etc
Weight reduction is a seat of your pants experience and will show up benefits on timed Sprints over measured distances like Santa Pod Race Strip, or a closed circuit race track. But again, R1200GS is not a performance machine, exhausts are so low sited on the bike (centre of gravity) that it would make very little 'real world' benefit. At the end of the day it isn't a track day project. Its an off road, on road Tourer and personally I think money should be spent enhancing that experience, and it's already quick enough.
Extra torque from an engine remap might help a lot if your loading up the bike with significant weight when touring, but honestly you've still got to scrub off speed from that lot, and more torque and weight puts more pressure on clutches ... so 'performance and speed' shouldn't be high on your list if fully loaded.
Also remaps are power modifications which increase wear on clutches, transmission, tyre wear, brake pad and disc wear and even rider attitude towards how you ride your bike more aggressively!! Plus Insurance Premiums and Warranty can be affected in the event of a significant claim.
So sometimes 'more' isn't always better.
As suggested earlier in this thread, if you are the type of rider who has 'mechanical sympathy' then you'll probably compensate out your remap extra power benefit by riding with 'less' throttle applied anyways. A rider with mechanical sympathy is a good thing (I'm in this category, trying for planned and smooth) but don't mistake this for slow. Haha.

Has the fuse tester assumed a few more identities ?

116 at the rear wheel, so not too bad. I couldn't care less about the figures tbh, it now goes as it should. Interestingly, both Euro 4 bikes he's done of mine are around 5-8% down on my Euro 3 bikes.
And, the petrol light came on at 170 miles on the way home, instead of 130/140 before.
...and economy is always a concern for you hey Nutty
Had mine done yesterday as well. E4 GS with akrapovic can and titanium headers.
Happy with mine.
Is it faster when going flat out? Probably not.
Is it smoother through the rev range? Yes
Does it pull better through higher gears when giving full throttle for an overtake? Yes
Smoother transition from zero throttle? Certainly yes. This was what I noticed the most, pre remap it was a bit rough when you first applied and advanced the throttle.
Peak power was 118 I think from memory. As mentioned though, numbers don't mean a lot - it's how it rides. It does feel better, particularly from initial throttle opening.
Would I do it again? Yes.

Had my standard E4 RT done started off at 106 ended up 112 ,bikes done 1000 mile.
Big gains in torque and now a lot smoother and it just feels right.
The other nice thing I now know it's not running stupidly lean.

I had my hexhead RT done in 2012 and the correction factor was different pre remap to post remap - one was DIN and the other I can't remember. There were a few like me who had differing CF's.
Good post !
To be honest I think taking every bike to Hilltop is a bit daft,but then he is called Nutty !!!
I took my Africa Twin to Geoff and it made a huge difference.And I can see that taking a GS there is possibly worth doing,seeing as it's at least 20% down on power to the class leader (that would be Nutty's other bike )
.But I have no plans to take my 1290R there. Why the need ? It seems to fuel very well (will find out properly in France/Germany next week) and it has more power than I will ever need.

I think you would be surprised how lean it runs despite feeling OK fueling wise
I seem to recall Andres taking his 1190R to Geoff and being quite alarmed at the standard AF ratio
But running lean doesn't concern me really......I'll let Nutty be the guinea pig....
If you are pondering along everywhere and watching rev counter then I wouldn't notice much difference either.
What I have noticed, that at 70mph the "hunting" has gone, the throttle response and progressive but smooth power delivery, unlike pre map. The fuel consumption improved to, and I rode like a twat back home. The bike is 2017 EU4. I am no riding god either, as only been riding big bikes for 13 months, but I can tell the difference.

They did run on the same Dyno, same day and with the same op.
Quoted figures is just pub talk, graphs speak volumes
Nutty was in front of me, I went in after him. His lighter bike (GS) V my heavier bike (GSA). Both bike probably built 2 months apart, (mine in December 2016) and there was a difference in power pre and post mapping. However I shall let Nutty to disclose the his information.
I was told, since my bike is still new, to thrash it towards 8-8.5k rpm, as top end is still tight (glazed) and a few more horses to be released, it will also aid in seating of all the internal components, resulting in better wear and less oil consumption.
I am Looking at getting an Akra end can but will likely stop there. As much as a full system sounds nice I don't think I could do 10k miles a year with it on. There is one up for sale on here but it is allot of money to part with.

Interesting posts. The key fact is that many go back. The bikes leaving the BMW mothership will run lean-to pass emissions. If Geoff can set up a bike that with no emission restrictions the bike has to run better, even if you cannot always feel it. It's all about expectations, mine is booked in for may EU4 standard bike. It has a surge at 3 to 4k revs which is annoying, if this can be smoother then job done
On a Dyno the weight of yours against his makes no difference, in the same way blue is no faster than black
However thanks for sticking up your graph, would be nice to see a few others of the day to compare.
Fair enough. It's been mentioned in a lot of Hilltop threads that Geoff offers a full refund if you're not happy. If I wasn't happy with the results, and could really notice a difference, I'd be asking for a refund.
I did say; it's about 116bhp IIRC. I'll stick the graph up later. The difference a full system makes (on a GS, at least) is negligible. Anyone buying one purely for power gains is going to be disappointed. I buy mine for several reasons, obviously power is no longer one of them!
I'm interested to see what it's like from standard. My 1290 has the Akra end can/ standard headers. As my GS had the headers fitted from new, I had to get the fuelling sorted quickly, but as it's always best to take a 'loose' bike to Hilltop, I think I'll stick a few miles on this one over the next few months before taking it up there.

But on the open road it does!
