It really does help when we can see what bike-year and what country at least.

Since the 950 has a more physical way to control power in 2nd and 3d, I would find it strange if doing this cutting the wires thing would work for it. What this mod does is just fooling the 990 ECU into thinking you're not in 2nd or 3d gear so it allows full power. If you do try it, please comment on the result!

Fuel consumption??

The Akro map makes the fuel consumption even worse than standard no... so does this not have the same effect...?

From what i understand,on the 950`s if you have already removed the EPC stuff and plugged the carb tops then you dont need to do this.See the HOW.

I did mine while I was doing the Canisterectomy and the SAS removal. Definitely hits harder in second than it did before. But I can't say which mod did what, because I changed 3 things at once. Bike feels more lively when you open it up so who's to say. Can't hurt to try it. Just cut 2 wires. If you don't like it solder them back together.

I removed the secondary butterfly valves in the FI throttle body of my '07 990S, which is equivalent to cutting the wires on the 2nd-3rd gear sensor.

Couldn't find any noticeable difference in performance or power delivery.

I think removing the secondary butterfly valves affect more than doing the gear sensor mod. That being said, it seems to be a personal appreciation thing. Some people say thet don't feel any difference, other say their bike is much more alive in 2nd and 3d.

Maybe depends on driving style?

The electronic part of the EPC triggers a solenoid on each carb to bleed the air through as I described earlier. If you haven't removed the EPC but want to try the mod out then the simple disconnect behind the panel is a good place to start.

For me, removing the SAS & EPC was a logical way to go as it adds nothing to the performance but does add complexity and therefore likelihood of failure to the bike. Much happier without the unnecessary junk!

I have a 59 plate 990 adventure and I had to remove the belly pan to get at the battery to fit some more accessories. whilst there I thought I would do the mod? cannot find the plug at all? is it still there on 59 plate 990 ? or am I missing it somehow?

This is a much better way to go about the noise issue than what Buell did on the 1125 bikes...they installed a solenoid that actually pulls the throttle back when WFO in 3rd gear for noise concerns. It's not real smooth, either.

The solution there is to install a resistor in place of the solenoid. The KTM mod is much easier, but a neat harness could be installed between the two connectors in place of cutting wires.

I would suspect 100% that it impacts US bikes too.

Yes, that is correct.

If you haven't done the SAS/EPC, there's a couple of relevant posts about disabling the 2nd/3rd gear sensor on the H.O.W.:

It should be there... are you looking in the right place? Best way to find the connector is to start off from the gear sensor (located right at the base of the sidestand) and then follow the wire until you find the connector. The connector should be right in front of the engine case.

The 2nd and 3rd gear limiter ONLY affects the very last % of throttle opening in 2nd and 3rd gear. It WILL NOT affect any performance "off idle or midrange" it will not make it feel "more lively or peppy" unless you are at 100% wide open throttle.

basically, before the mod your throttle opened 97% of maximum and after the mod it now opens 100% (yes the difference is about that small)

hope this helps,

cheers
