• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

SM630 idling high + some more. :)

Today i went to my dealer and changed oil and oil filter at 200km (124 mles).
Since the bike is brand new i followed the advice from this forums and gave it a early oil change.
At the same time the dealer adwised me to unplug the O2 sensor and install a "cheating" box instead. Is this what you call the PU kit?
Well after this i now have an idle at 2700rpms. This is too high in my opinoin.
The temperature when i was riding today was -10 degrees celsius, (14 degrees Farenheit) Could thtis be the reason that i have such high idle? Since it it so cold here right now?

When all that is said the powerdelivery was much smmother after the o2 sensor was disengaged.
I can see you talking about the 1000km servoce to install this, but in my opinion the motor seems to run more correctly so why should i wait to do this? It was both my dealer and the Hysky importer in Norway that advised me to do this.
At last i can tell that riding the SM630 on spiked 17" knobbies on the winter roads here when the sun is shining and it is -10c is heaven to me :)

Doesn’t it have an idle adjuster knob like the 610 on the left side behind the motor ?

First thing to check is that the cable to the air valve on the left side of the throttle body is seated properly.

It'd also be worth checking that nothing is interfering with the correct operation of the throttle. eg incorrect routing of cables...

The idle adjustment screw is horizontal at the bottom of the throttle body on the right side, just behind the front edge of the air box.
 
The SM looks great. Like all Huskies they bed in slowly and just become so reliable and a real joy to own.
 
Turn the idle back down. The idle speed increase is normal when installing the power-up kit, as it gives you a richer air/fuel mixture. You'll also notice that the tach is more steady at idle, rather than jumping all over the place like it did wit the O2 sensor in place.
 
Yes! It´s to be expected that idle is much too fast after the p/u kit is fitted. Look at the relevant passage in the manual that came with the bike and use the special spanner in your bike´s tool kit to re-adjust the idle (but make sure that you do it while the engine´s warm). It´s as jtemple says. You´ll have a whole new and very satisfactory bike.

Ditto!
 
x 3 on to be expected comment and too change the idle with the special spanner, not sure why the shop didn't do this too be honest, did they even tweak the mapping of the bike after installing the power up kit?? Ask them politely if you can have the maps checked on their computer and then they should do it if they haven't already (this is if lowering the idle dosen't simply fix it).

BTW, Nice looking 630! What tyres are they, I'm thinking next winter i'm gonna get a similar set and then swap back too my curetn tyres.

In the rear i have a 130/80-17 Maxxis Dual Sport M6006
In front i have a 4.60 - 17 Cheng Shin C-858
Both tires is fitted with spikes for lorry trucks, but not too many, so i don't loose the grip on asphalt.

I talked to the shop, and they have simply forgotten to adjust the idle. Well i did it my self today.
I also got a full workshop manual from them :) I'm shure it will come in handy some day.
 
A new EFI comes with the p/u kit (look at the "Special Parts" catalogue on the Husky site). So re-mapping is not required. Setting the idle only takes a few minutes.

I didn't get a new EFI unit with my p/u kit. Here's what I got:

8000A7724 CK HUP Oxygen Sensor Plug
8000A7749 CK HUP Gasket, O2 Sensor Plug
8000A6750 CK HUP Oxygen Sensor Connector
 
I did. I have a copy of the pdf right here. I'm not seeing what you're seeing I guess.

The only thing I see that includes an ECU are the arrow cans. I don't think that's the power-up kit everyone is talking about :)

The O2 bypass kit that I have isn't in the special parts document at all. It costs about $40 and gives you a whole new bike. Best $40 I ever spent on a motorcycle. The Arrow cans and ECU cost a heck of a lot more than that.

Those tires are sick! How do they compare to the original SM wheels? Also I see your original post was in Feb. how is tread on those tires now? and how many miles do you have on them? I am very interested in getting a pair for my SM630.

Took my SM630 to the dealer who recomended that:
1) The ECU be switched from A Mode to B Mode.
2) The O2 sensor be taken out and replaced with a plug.
The above was all done.
Idle is now at 1450 rpm.
Bike has much more grunt right from the bottom all the way to the top.
Power delivery is smooth and all EFI issues are gone
Bike is now much faster
Apparently the factory released the bike in A Mode which is a low power mode because, in case there were some inherent faults in the new 630 engine, Husky didnt want to have mass engine failures on their hands.
Now that the engine has stood the test of time, Husky are now happy to have it switched into B Mode, i.e. "full power" mode.

I believe the bypass plug that replaces the O2 sensor is what switches the ECU from A to B. There's a resistor inside of it.

Well i had about 500 km's on the tires from February to late April. I would say about 50/50 on snow and asphalt.On bare asphalt the bile is of course much more stable with the SM tires. It feels a little "nervous" with the knobbies on the winter, and i would think a 21 in front makes the bike more stable and easier to handle on snow and ice. If this is because of the truck studs i cannot say, because i did not try the bike with knobbies without studs. But i will have this option in the next winter also. The treads show no wear as i can see, and all the studs are still in place.
In February the bike was brand new, so i began the break in of the bike in slippery conditions, so it might be because of careful driving that the tires still looks so good.

My dealer also reccomended this.

Will this void warranty at dealerships???
 
I too installed the power up kit and my idle jumped to 2600. turned it down to 1600 because that sounds right to me.

What idle does the manual recommend? The dealer didn't give me a manual :(
