• 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 The previous version was outdated and no longer supported.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!

Gearing Recommendations for 630 SMS

So, just to clarify, the SM ECU + JD Tuner, does NOT produce the same performance as the TE ECU? To get the max from a modified bike, we need the TE ECU AND a JD Tuner?

Sounds that way, I will be trying all SMS/TE/JD combinations next weekend on my SMS(something came up this weekend)

My TE only has 3 hours and 70 km on the clock - still breaking it in, so I cannot make any WideOpenThtrottle comparisons

From a casual, easy riding point of view, the TE is smoother on - off throttle and has better off - on throttle pickup and cruises stronger.
But make no mistake, the SM with SM ECU + PU + JD Tuner produces storming acceleration that I am very very chuffed with.

Again, this is just my experience on my bikes in my environment.
Other members in different parts of the world may have diferent experiences.
Any takes out there ?

Please update. I may seriously consider "experiencing a short in my SMS ECU" and requesting the dealer order a TE ECU. Make Husky do what they should have done in the first place.
 
I just opened my airbox.. what a difference :eek: 2nd gear wheelies are sooooo easy now. But that's also how it should be on a 600cc bike :D

With or without clutch?

You have stock pipes, power up, 15/44, and JD power surge, right? Can you post a pictures of the new holes in your airbox?
 
Yep mission impossible :excuseme:

@Rocko Clutch of course :D

Anyone here have access to a TE 630 with PU that they can compare their SM 630 to and see if 3rd gear wheelies at 67KPH ( which equates to 42MPH ) are possible ? :excuseme:

I would like Independant confirmation on the SM / TE difference,
before I pull the trigger on a TE ECU for my SM,
yes, the dealer will arrrange it for me.
 
I wonder if it is possible to order the Arrow ECU. I mean if someone that already installed the Arrows on his 630 has a damaged ECU for some reason, the dealer should be able to order it too.

Also would it be possible to use a 610 ECU? Or would there be a problem since the 630 and 610 have a different top end? Anybody got an idea? :confused:
 
I haven't purchased my SM 630 yet, but plan on doing so tomorrow. It seems like everyone is clutching at straws and really doesn't have a definative answer to the question/problem of the acceleration/freeway cruising. Surely someone from Husqvrna or one of the tech's should have it down to a science and know exactly what to do.

It's not really that difficult...
With stock gearing, 75mph will be ~5200 RPM and will make your butt tingle after a short while.
Going smaller on the front sprocket will wear and stretch the chain more quickly than stock.
Going larger on the rear sprocket or smaller on the front sprocket will increase your RPM's at any speed but give you more torque to the wheel.
Going smaller on the rear sprocket or larger on the front sprocket will reduce your torque to the wheel, but give you a more comfortable cruising RPM for the highway.

With stock gearing, 60 is perfectly comfortable, the buzz starts around 68, 75 isn't terrible, but 80+ gets a little uncomfortable after any length of time. For many this isn't an issue, but we have some pretty fast interstates around here...

If I ever have transmission problems, I'm ordering a TE gear set to drop in, for the higher 5th and 6th ratios. I think the SMS should have had these ratios to begin with...

If you want aggressive, dirt bike style, low end throttle response, ask your dealer if he'll swap-in an ECU from a TE630. (Assuming that you're buying new.) Ride the bike around the parking lot with each ECU to determine which one you like better. Otherwise, adding a JD Jetting 6x is a simple modification that can make the throttle respond more aggressively.

If you're just looking for a commuter bike, the SM630 is fine without any modifications other than the power-ups. If you're not going to ride over 70 MPH, add two or three teeth to the rear sprocket for a little more grunt at lower speeds....
 
RDTCU,
I understand how the gearing works, but it's the combination...airbox, mapping, exhaust/un-corking. The whole works. It seems like it could go on forever. I've read posts where some like their 610 more.

I agree, the TE gear set is probably how it should have been.

I have run a TE ECU in my SM and it made the SM run virtually the same as the TE, i.e. much nicer.
Simply put the TE ECU is the ECU I want in my SM.

The TE and SM ECU's must be mapped differently in areas other than fuelling, eg Ignition timing.

While you are at the dealer you may want to enquire into what would be the effort and cost involved in replacing the SM 5th and 6th gears with TE ones......er ... before you do that though you may want to put your flame suit on...
