Hey everyone. I've been on SMJ trying to figure out whats up with my 630 and thought I'd poke my head in here and see if anyone else is in the same boat I am... I bought the SM630 in early January and was really super excited to finally be getting motarded! This was going to be so much fun riding with my buddies. And couldn't wait to start playing with my new toy. For the first couple months I took it pretty easy and didn't bang on it to hard. I wanted to make sure I got some heat cycles through it and things broken in rather than just broken. Little wheelie here and there but mostly just going through all the gears and doing a couple oil changes. This is about where things fall apart; figuratively and literally... Even during break in it was geared ridiculously tall (15/38) I didn't realize it at the time due to my lacking experience riding singles but it would lug in 1st. I decided to gear it and with a stroke of luck a local dealer had a 43T Gas Gas sprocket in stock that fit the 630. How lucky was that? Gold link RK chain for the sessy factor and wow what a difference (15/43) made. It wasn't lugging in 1st anymore and across the board it was a completely new bike again and was so much better, worlds better. Once I had a 1000 miles on I decided it was finally time to open it up. All day long my buddies on a 610 and KTM 625 were just beating the pants off the 630. It truly was pathetic. They didn't believe me until we traded bikes and took turns riding the 630 around. All three of us agree; something must be wrong. With that I took it in to a local shop and had a dyno run done. Completely stock minus sprocket I did it pumped out almost 40HP and 30ft/lbs. The good news was that it was really really lean and could be fattened up a bit. So on my way to the dealer to pick up some parts we started talking about the dyno charts and how it did. Thats when they said they had a full titanium Leo Vince 2 into 1 exhaust for the 630 in stock and would make me a deal on it. Well... It was much better once I had the dealer map it and could get it back out on the road. My backside isn't calibrated but it sure felt like there were some significant improvements in power moving it down the road not to mention the ti system shaved at least 15lbs off the bike. So to get numbers that are calibrated I took it back in and had it dyno'd with the new pipe. And to my dismay it peaked at almost 1HP and 2ft/lbs more than OEM. Across the whole curve it was better but still I was expecting to see a little more than that. Good news again is that it is a little rich now and needs to be leaned out a bit. RED = Ti Leo System BLUE = OEM System Up until this weekend I didn't have much to compare this data to. So two of my buddies have 610's with the same full Ti Leo Vince exhaust and came in to get dyno'd. One with an opened air box and one with a stock air box. I haven't made any print outs yet but the 610's dyno'd in at 48HP and 46HP respectively and the second was scary lean. Fatten it up some and open the air box and I'm sure it'll be right up there at 48HP. Last Friday I ordered the MOTYdesign 6 cell LiFePO 1lb battery which will shave another 9 pounds off the 630. It should be here today so I'm interested to see if I can feel that weight loss. Nevertheless, I'm still a bit disappointed. Aren't the 630's supposed to be putting out more power than the 610's? Its just very disheartening and I'm hoping that there is something wrong that can be fixed. I was going to get a Power Commander V and AutoTune but decided against it after my last dyno run. At this point I'm not going to put another dime into it until I can get some kind of confirmation one way or the other. Hopefully there's someone else out there that has a 630 as well and can help me do some R&D. I've done quite a bit and have documented most of it on SMJ. http://www.supermotojunkie.com/showthread.php?112289-My-Personal-2011-SM-630-Review Take care people, and I look forward to reading your feedback.
Yeah that does not sound anywhere near right. I would think you should be in the 50-55 range stock. Not sure where to look for that lost HP.
I started comparing all the dyno sheets I have and see a pretty funky trend; cc's go up and HP goes down... 510 = 53HP 610 = 48HP 630 = 41HP Kind of interesting... But I have no idea where that much power could be lost. You would think that if it were mechanical that would have stood out a long time ago and been fixed so the only logical place to look would be electrical. Maybe the ECU is funk but I won't know until I can find someone with a 630 that puts out more than 41HP.
Man that sounds suspect -- Ordered a 630sm and now been doing some reading and getting worried - keep me in the loop please --41hp is just going to be like kissing my sister --aaargh going to test ride a new sm 630 with 400km's on the clock this week-end taking my 610 te with to compare --have the O2 conversion on my 610 with a Arrows pipe and love it to bits ---
On paper the 630 should be more powerful than the 610! Husky claims 20% power increase More ccs More compression Bigger throttle body DOHC Something is amiss!
[/quote] 510 = 53HP 610 = 48HP 630 = 41HP [/quote] I bet the 630/610 has WAY more torque though. AND, your 630 should by all accounts have more power than a 610.
The 510 came in at 36ft/lbs and I cant recal what the 610's were putting out without looking at the files...
Agreed; thats why I'm here. I cant seem to find another one that has dyno numbers. One guy did the same exhaust I did and had some dyno time in but I haven't heard from him yet... The dealer was supposed to be calling around asking as well.
What is up with your resistor plug (SMJ pic)? No offense, but it looks like a radio shack, diy special with a touch of heat shrink? I bought my resistor plug, p/u kit when I bought my TE 630. It is a Husqvarna part in the $25 range, # 8000 A670. I know guys have made their own plugs, but I would get the genuine Husky part, in the pic. Try that! MotoXotica had the plug in stock both times I needed them for my TE's.
Do the 630's not come with a 'power up' kit? My 09 510SMR came with the Lambda sensor bypass, fitted that and ditched the 02 sensor. The dealer had already binned the super restrictive air box screen. I've sinced ditched the flashback as well and fitted a K&N and gutted the end cans. You've already fitted a decent pipe. So that only leaves the throttle stop limiter. Does the throttle cam on the injector body have a restricting plate fitted? If so ditch it. It might just be you think you're getting full throttle but you're not. I don't know, seen your post on SMJ and might have missed you mentioning this? not 100% certain if the 630's even have this restrictor but it could be something that simple. You shouldn't be spending £1000's to get average 600cc single performance. Bear in mind, the 610's and 630's are not as light or as revvy as the 510's. Also consider, when I first got my 510 I couldn't even keep up with my mate on his Yam XT660X weighing around 60kgs more and making less HP... I'm sure you'll get there
There is no throttle stop on the 630's. There is a super restrictive baffle in the air box on the USA models. It is behind the air filter element. Has that been removed? It is call a "labyrinth" in the parts catalog. Edit: I just read your latest SMJ post. I see your labryinth was never removed. It slipped my mind to mention as my was came in a card board box and not my air box when I got my bike. Sounds like that little 'ole labtrinth can rob a bike of 15hp.
In Europe, we´ve more experience of serfdom than you´ll ever get. We just love the feeling of being whipped by bureaucrats. I wouldn´t last a single day with "NOT FOR ROAD USE" stamped on my zorst. The Arrows come with a neutral looking "Husqvarna" stamp which leaves our friends in uniform with a quizzical look and no grounds to interfere. I left the cat in the exhaust and taped the end of the lead to the frame. So it looks hunky dory, goes like a butcher´s dog and is very LOUD!
Ah, well that would explain it pretty simply. Think that and the exhaust would be the first places to look. Things have to flow in to flow out. The restrictor plate in the 510's left like a pea sized hole. If something like that's in the 630 look no further. +1. Anything with not for road use is fair game for a fine here and they DO look. I kept the OE cans, gutted them but they still carry the Husky official stuff and look legit like OE but flow. Perhaps I'm being dumb but can't work out what you mean there? Sensor lead??
I tried to get the airbox face plate off but two of those awesome little brass inserts in the airbox spun and for the life of me I can not get the airbox face plate off. I eventually took the whole airbox off and did everything I could aside from cutting to get that faceplate off. I'm going to try and go to the dealer today after work and ensure that another warrantied airbox is on its way (and pick up my replacement front caliper bolts that fell out on the road somewhere). But I'm also going to call my shop guy and ask if he'll be willing to do a really quick and very cheap no chart just tell me what the numbers are dyno run with no air box whatsoever. That should tell me what needs to be done. If I have to put a K&N cone air filter off the end of the throttle body then so be it. If I ditch the whole air box thats just more weight savings right? FWI, the MOTYdesign 8cell battery is AWESOME! and took 9 more pounds off the bike. So between the Ti exhaust and the battery the 630 has lost about 25 pounds! Now if only I could lose that much weight
I would not run it without the airbox, it will probably make less power and be way lean. Needs to be right, stock airbox without the baffle. I bet you pull that baffle and you find all that HP your missing. Then a quick iBeat tune up and some more miles and you will be happy. I hope.
+1. And the thing will bog when wet. If it's the same as the 510 I think all your probs have been due to a £2.00 piece of legislation complying plastic
The Arrow cans come with a different ECU, correct? I wonder how much impact that ECU has on the bike's Horsepower? You've got to imagine that Husky's 630 Horsepower claims are based on a bike running the "different" ECU along with the Arrows.
I don't know about the Arrow system but the Leo Vince did not come with an ECU and the bike had to go in for an iBeat mapping to run correctly.
