Pro Shift Kit

(the microbearing detent arm and F-Pro shift spring kit)

Virtually eliminate missed shifts and false neutrals. Quicker shifts.

The 1090, like the 690, has lazy shift action. Not what you want when Super Motard racing or jumping those doubles or splitting that lane.

Factory Pro's opinion is that if you nudge the bike out of one gear, it ought to go into the next gear.

 The stock shifting can be sketchy under even recreational use.
Some individual bikes, more than others, have a propensity for false neutrals and missed shifts in critical situations.

Changing the oil can make, maybe a 10% difference and perhaps moving the lever up or down can make a 10% difference - and this shift kit is a stunning 100% difference.
In other words, use any old oil and have your lever set almost anywhere realistic and it will still shift well.

Virtually eliminate missed shifts and false neutrals.
Installation: About 1-2 hours - no case splitting required. The clutch basket  has to be removed to install the arm and spring.

Available with
Hybrid Ceramic Microbearing

Fuel injection tuning

TuneECU screen

KTM 990 SM, 2013 dealer plug location


Tuning Specialist

The ktms are variable - an occasional few run fairly smoothly and some (most) surge a bit and many are super abrupt on the on / off / barely on throttle operation - kind of like what you don't want on a big, strong, torquey bike.

Many bikes are just not enjoyable to ride on a trail. The fuel injection tuning is one of the few faults of the bike.
It's what happens when, I assume, manufacturers sublet out FI tuning to non-motorcycle specialists for emissions and drivability tuning.
It's possible to make the KTMs run much smoother - better.

Proper tuning fuel, ignition, crossover tables, device activation tables will smooth out the lowend and improve power delivery linearity to make the bike sweet and nice to ride. (and 'oh darn", will make more peak hp, too  :-)

Wheelsmith / Factory uses the EC997 dyno - with Realtime HP and torque readout and a 5 gas Exhaust Analyzer - and that's why results are likely to be better than a dealership level dyno that only "tunes to an air-fuel ratio" (as if there is some magic afr).

I've heard reports in MotorcycleUSA.com that common dealership level dynos can take "120 dyno runs to tune" a KTM. That's abusive to your bike. It's fine for a magazine test bike, but not yours.

The Factory Pro EC997 and it's 5 gas exhaust gas analyzer derive loads more tuning information per dyno run - providing the most tuning information in less "engine runtime" -  6-10 runs would be max engine runtime.

Wheelsmith has been tuning KTM twins since the first 950's came out - in fact, the 950 jetting kit that Factory Pro / Wheelsmith developed is the best performing 950 jet kit available to this very day.

Wheelsmith (Factory Pro's R&D division) is available to tune your 990 - be it TuneECU, Tuneboy or a simple power commander.

Note: A power commander is limited in what it can adjust and can't tune for maximum smoothness as well as TuneECU or Tuneboy.

We suggest TuneECU at this time - it's reflashing the stock ECU with custom mapping and tuning -
TuneECU is more reliable than adding an aftermarket fuel controller.

TuneECU re-tuning and test riding

Oct, 2015

Hi Marc,
You dyno tuned my trackday 990 last year. You might recall that my wife and I went over to Point Reyes while you had the bike.

Just wanted to say thanks for a good job and I am a satisfied customer. The 990 is running smooth and crisp and the throttle is much more behaved.

When the opportunity arises I have posted the good results of a tune done by you in your shop. Hope you have had some business as the result.

       Hello Marc!

Riding home last night thru traffic and lane splitting was successful.
Previously, that would have been a very scary proposition but the 990 is
pretty smooth in that environment now. Thanks.

Thanks again for your successful efforts.

KTM 990 Adventure, 2007

both runs are with Leo Vince slipons with db killers installed

blue - untuned

red - re-tuned with EC997 dyno

lowend and part throttle on/off is night and day smoother
I once had a ktm 990 that was stubbornly overrich at about 1% throttle.
Not .5% and not 2% - just at 1%.
I tried the IAP table. I tried the TPS table. I tried changing the FL table without results.
After the customer checked and reset sensors, it was still bad at 1% throttle.
Turned out to be the crankcase vent check valve.

thanks to Chris Parks


Where is the  TuneECU connector located?
(aka: Where the heck is that darned connector?)
Remove Seat with key.
Seat lock is on the LH side, below seat.
There are 2 x 6mm headed bolts to remove.
A 6mm T handle will reach. (not an allen wrench - a hex wrench)
The two bolts are removed and the plastic cover is lifted up from the rear.
Here is the hidden TuneECU connector.
It's white.

If you were rummaging around on the bike, you might have found one other white connector near the steering head. That's not it.....
The cover has a "blank" plug
Turn the connector latch side up.
Unintuitively, you lift UP / OUT on the latch to unlock.
Blank plug.
Connect the TuneECU connector.
TuneECU cable connected to bike.
TuneECU cable connected to the computer's USB port.

The white connector is a dongle for a different chip burning software system.
Start TuneECU on computer.

Load a compatible map into TuneECU.

Start the bike.

If magic happens, the software will flash red, red, red, orange, orange, green, green, green, green in the bottom, right of the screen, read out the map ID number and the diagnostics will work.

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
