Can I switch between SEL1 and SEL2 with stock dash

I did a search and read many posts and cannot find the answer. My current bootup puts me in SEL1, which I believe to be full power. Is there any way to switch to SEL2 (wet/mud map) using the button on the stock dash or do I have to install some kind of aux switch/button? 2010 TE450

You need the "dual mode" button. Husky makes it as an option available at your dealer.

Costs less than $40 here in Australia. I imagine it would be cheaper over there. Its a simple plug and play button that you zip tie to your bars and gets plugged in behind your headlight.

So I am gonna assume I can install a radio shack pressure button and connect it to the blanked off wire pair in my headlight area, right?

$40 is about $35 too much.

I think they are 15-20$ in the US.... now's where you say that's about 10-15$ too much

There has been some speculation- but It is just a "normal off pushbutton switch".
I have the OEM "dual mode" switch its nice to have the right plugNplay connector.

Sel2 is kinda useless if you ask me, It takes a bit to cycle between Sel1 and sel2 and back and forth (like 5 seconds of holding the switch in)- and Sel2 (as "the wet" mode) basically sounds off in power sooner -starts to seriously drop power at 6000rpms or something. The bottom may be a bit softer. Sel2 is a diferent ignition map not fuel map. I figured if its available for the bike it should be on the bike. But I rarely if ever use it.

SEL2 sounds much better for the riding I do, smoother power, less breaking the tire loose when the rush comes on, I dont need the rush, but if its not a different fuel map as well, as in less fuel, I guess I'll skip it.

For me- running in Sel2 past 6000 rpms or so- is intolerable. The motor sounds strained and is weak- so you will change your shift points and never run any revs... in that regard you might increase you fuel mileage. Its like following George's 'slow break in' method/ ignition map. In really really technical sloppy stuff it may be helpfull to ensure you don't over rev and and loose the back end- or loop it out in unpredictable loose to perfect traction situations... But you can do that easily with throttle control and clutch control. I just don't like to have to wait to be able to push the button 5 seconds to go back to Sel 1 for full power. So like I said - its rare that I use sel 2- real rare.

Im only middle aged. I like spending money. Its good for our economy.

Im the same. I used mine for a while, until the novalty wore off.
