2013 GSA midrange missing...

[Grb]

Hi all,

Moved from a klv1000 (vstrom) to the GSA this year, and the low rpms on the GSA are a great improvement, and I spend most time around 2 to 4.5krpms

Twisty B-roads are a delight up in 4th / 5th gear until you need a little extra to overtake... the midrange power seems to die off until a big hit up at the top end.

Dropping to 2nd gear gets you by, but it seems a little out of character to need to get over the midrange dip.

Only 2500 miles on the bike so far, so maybe this improves ?

+ The klv1000 had a PC3 to try to remove the horrible low rpm leaness... maybe the GSA needs something similar for the midrange?

Hill top !!!

Yes Hilltop!!
Sorts out the midrange dip
Plenty of happy customers on here. Do a search

I use a PC3 on my 56 plate GSA and it's excellent but you will need a PC5 for yours. De Catted headers are also a way of getting that mid range back but don't have the same oomph as a well set PC.

The latest craze is Hilltop where he alters the ECU and the results are excellent. thereis a long thread in this section if you want to wade through it.

I have the KLV and GSA. Different as chalk and cheese. Not noticed the mid range dip on my bike. Doesn't mean its not there tho.

The KLV at 3200 rpm is awful. Have you still get the PC3 and want to sell?

De Cat and Hilltop !

Try 3rd gear

I do have the PC3, and happy to sell, to fund whatever the GSA needs...

Try the 2014 model. Hopefully the midrange will be better or you can always twist the throttle to the stop.

 

[Norfolk Tiger]

De Cat and Hilltop !

+1 I agree

At 2500 miles the bike is hardly broken in. Riding it at such low rpm's (2 - 4.5k) sounds like killing it, especially with such few miles. I've a 2010 model and rarely ride below 4k rpm. Cruising is between 4.5 - 5k, riding a twisty road +5k, riding hilly stuff (Alps) +6k and more. Get near redlining regularly. This is what the GS was made for, or at least it was for me!!

it's not a VFR400 you know?

not sure i understand properly, but what im picking up is you are bimbling along in 4/5th gear and finding you need to drop down to 2nd to overtake
Im in my 4th year of owning gs's and have never felt that much lack of power, my style of riding though is to always be in an appropriate gear for the speed im doing, ie. keep bike responsive in this case over 4k revs, particularly on bends and obviously on preparing for an overtake.
i never find myself needing to drop more than 1 gear or rarely below 4th to get the pick up you want to overtake safely

I'm guessing.. they're not missing any midrange? ;-)

It's not the lack of power overall, it's just that it takes a bit of a flat/dip around the midrange before a big surge towards the top end.

I've noticed a few of the dyno charts posted here which also show the stock curve going flat around 5k to 6k rpm.

I'm going to consider the PC-V to tweak just this flat spot, since the rest of the range is excellent, and very smooth in low speed busy traffic.

The EU noise rules require a ride-by noise test at mid revs. The ECU is programmed with a flat spot because it makes less noise.

The simplest solution is a remap. The new map will have no fueling dip in the mid range and allows the engine to make full use of its original design over the whole rev range. If the bike is to be used in areas where fuel is quality is questionable just have it mapped on that fuel.
