Ok, I finally got the bike out of the shop after waiting almost a month for a clutch cylinder seal ( dealer stole one from another model ) and all my first impression are the same ... EXCEPT ... the fuel injection is awful! Low speed surging, bucking, stalling, backfiring and very erratic idle. How come the SMS does not come with a powerup kit? I want to keep the stock exhaust but what can I do about about the f.i.? I'll keep riding and building up the miles as I know these things get better with time.
But there IS a power-up kit. The Lambda sensor is disconnected (and ... if you want to ... removed and a plug is inserted instead) the lead to the Lambda sensor is then re-connected to the plug that comes with the kit and located anywhere you want out of sight ... and that´s all there is to it. Doesn´t take long and is inexpensive. Most have found that you then have an entirely new bike: no more surging; once idle had been reset, it´s stable; fantastic power, no more stalling and no back firing. This is how the bike was obviously designed to be. I left the Lambda sensor in as camouflage and re-plugging´ll only take a few minutes once every two years for the local environmental test.
Thanks for the info, I'll look into it. When I bought the bike it came with a tool kit and that's it. I asked the sales guy if there was a power up kit and he seemed pretty confused and twisted the throttle and said there was no throttle stop so that meant it didn't need a powerup kit. This is such a fantastic bike, I can't wait to get it running right. Looks like a trip to George's for the 600 mile service!
Same problem as you and did not improve with time. Power up kit should be called "FI upgrade kit". Bikes should not be sold with the FI as is. Safety issue as far as I'm concerned. Mine stalled while turning after leaving a stop sign. Rear wheel locked up and bike fell down on pavement. Lucky I didn't get run over. Suffered with crappy FI for over a month until PU kit installed. Different bike now!
Thanks Willie, I almost had the same thing happen. After stopping to fill up with gas, I entered the street and the bike unexpectedly stalled in busy traffic ... didn't fall over but sure had a scare! I totally agree with you that this is a safety issue. I'm not interested in any kind of hop-ups like pipes, cams, pistons, etc. , I just want the thing to run decently. I'll let you know how the FI upgrade goes.
By-passing the lambda (O2) will richen the mix and make the bike run better. The extreme lean is for emissions. If you feel it's dangerous to run the bike lean while you're breaking it in, do the by-pass. Warranty is likely gone at that point but it's a choice.
My dealer enquired about the warranty. The German distributor informed him that the kit installation would automatically be stored on the bike´s black box but they´d still honour the warranty as long as it wasn´t raced. They practically admitted that the bike was not expected to be run permanently without the kit but it had to be delivered without for legal emission reasons (E3). (B*gger E3!)
Don't leave the O2 in if the wires are not connected. It needs to be heated or the sensor will go bad due to carbon build up or something like that.
Think it´s better left in place so as not to provide the law with an obvious excuse to haul me in. And I´m not planning to use it ever again.
Same as. Love the bike as a sorted machine but pre that, stalls and some scary moments. Posted this is response to yet another dude in the same boat: Zupa, I don't know the answer to your question but I've also got a 510 on an 09 plate and is fitted with PU kit though still standard pipes. What does me is the lengths we folk have to go to to sort these bikes - most bikes - into the machines thy're meant to be JUST to get around the friggin ridiculous EU/US emissions crap. The Icelandic volcano is still spewing more shit into the air than my bike ever will if I rode it flat out for the next ten thousand years. Yes, all scientifically verified by NASA of course.. I'm hoping just to take mine to the dyno and get it run up and get the O2 levels good to run not lean and responsive across the range. At MY expense! I mean the amount of raw materials and carbon footprint blah blah that goes into researching/making all this aftermarket stuff, for the emissions that bikes produce for the limited amount of time they're on the road v cars/trucks etc they should be 90% emissions exempt from the factory and ready to roll. Sorry for the rant dude. Just fed up with seeing so many guys struggling to sort hard earned machines with yet more hard earned.. Out
Too true moto66! But supopose we must be grateful that there´s at least one bike maker that provides us with the ability to get back to what the engineering team originally inteded the bike to be. And the PU kit isn´t that expensive and is very easy to instal.
I agree, I got my UK bike with all the necessaries to do the PU, bar free flowing silencers. I know the manufacturers must be pissed also as every bike is a dumbed down version of what it could be due to emissions regs. Thinking of buying a new van, VW, 140hp version, that'll be £xxxx more thanks. We all know it's just a setting in the ECU. Husky are good and now the bike is sorted I'm more than pleased. I've had bikes for 25 years and love the tuning/sorting but not things stalling or running so lean they're at risk. It's just painful to see everyone else here and other sites going through the same puzzling process to get a decent running - despite being a sound product - machine. Not that I get annoyed easily or anything
Sorry guys but I just got back from the dealer and they once again said the 2011 SMS630 does NOT come with a power up kit. The TE 630 comes with a power up kit but there is nothing for the SMS 630. They did say that when I brought the bike in for the 600 mile service they would recalibrate the f.i. to the latest factory settings and the bike would run much better. If there is a plug for for where the lambda sensor was connected please give me the part number as he was not aware of a plug specifically for the SMS model.
8000A7724 CK HUP Oxygen Sensor Plug 8000A7749 CK HUP Gasket, O2 Sensor Plug 8000A6750 CK HUP Oxygen Sensor Connector Should fit SM also.
Thanks Willie, I'll be taking it in for the first service in about 2 weeks and in the meantime I'll order the parts. Other than the lousy low RPM fueling the rest of the bike ROCKS!
There´s a story doing the rounds here in D that Ducati had been "adjusting" all their bikes sold here directly before leaving the showrooms. Then they even started mentioning the new performance in their adverts ... until Kawasaki went and purchased one, took it to bits and then notified the authorities, resulting in a high cost prosecution. So maybe it´s best NOT to mention the PU kit!
Good point ... here in California I'm sure the " Greeen " Police would like nothing more than to catch a dealer commiting the heinous act of making a motorcycle run properly and sueing them out of existence. I can see the headlines now, Husqvarna Motorcycles are directly responsible for global warming.
I would much rather keep the O2 sensor in place and have the FI tweaked to improve runability. I don't particularly care if Husqvarna gets raked over the coals for the f**kup. They should not release bikes until they run well AND meet emissions standards. Maybe there will be an update in the near future. Until then the PU stays!
That was my opinion too! But there seems to be no alternative for manufacturers but to limit power output (by leaning etc) in order to pass legally imposed emission limits. The bike was designed to run perfectly with the PU kit. I wanted to get rid of my 630SM a.s.a.p. ... until it was uncorked while at its first 1000km service. It now runs perfectly: smooth in slow traffic and pulls your arms off when needed. Handling is superb ... as are the brakes and suspension. Just unhook the lambda sensor, re-plug, stick on the twin Arrows, plug in the new EFI and it´s the bike you´d always wanted!
