any idea if that also needs to be done for european models? if not, is the airintake as good as it can get, no holes need to be drilled?
I'm sure I'll have it done a couple more times and as of my last dyno with the pipe and iBeat its running pretty rich so I was hoping that opening the air box a bit would lean it out enough that it would still run fairly well. I've started formulating a plan to get those bolts out so I can get into the airbox. Its amazing how difficult it is to shear the head off of a bolt when you want to, normally they just pop right off
Arrows is the system Husky uses --and comes with the ecu as part of the kit here in SA. The answer to the mystery may be that ECU --and gues what i tried to buy one seperately --sorry -only comes with the pipes was the answer i got
After using my cordless and slowly drilling the heads off of two of the bolts... I got the airbox apart and could finally see what this labyrinth business was all about. Interesting, very interesting... I pulled it out, put the air filter back in, put the face plate back on and rode in to work this morning. I'm pretty sure I could feel a difference but it sure wasn't night and day. I can without a doubt hear the intake better now which can play tricks on your mind when trying to feel a difference in power. But it seemed to accelerate harder while rolling down the road and I want to say it added a tiny bit of low end grunt for 2nd gear wheelies but really cant say for sure until I can get on it for more than 4 miles of freeway and .5 miles of industrial park roads...
Good to here you got in to your air box Master_E! You are running the TE gearing right 15/42?. I am curious what the dyno will say now that you got your air bix flowing better. I have iBeat and see that our ECU's give us CO adjustments with the p/u kit installed. That is awesome!
The Arrow slip-ons come with their own black box (as can be seen in the special parts catalogue). The Arrows are street legal. Apart from the weight reduction, I can´t see the advantage of changing to a single zorst system. Bikes with a single muffler are so often adapted to dual ... and dual systems adapted to single. Suppose it provides an opportunity to be creative and is thus part of the process of bonding with the bike. After upgrading the 630 with the Arrows and the p/u kit, ´twas a totally different bike. And it´s got P o w e r !
Are you using the OEM genuine Husqvarna resistor as mentioned in this note or an after market product?
Yes I have the Husky p/u plug resistors on my bikes. I know it is just a single resistor in the plug that is available at an electronic store, cheap. I chose to get the Husky part rather then chance making them myself.
I have whatever the dealer put in it. It is just a simple resistor and not the Husky replecemnt. For sake of understanding beyond a shadow of a doubt though I'll ask them for the details of exactly what was done for the P/U kit. It came to me all done so all I know is that "its been done"...
You may want to just use an OEM Husky product. If I was faced with your "slow" 630, I'd try to eliminate every potential issue that could possibly limit the bikes performance.
Yeah, +1 on that. not sure what the right component is for the 630. for the 610 it was 2,2kOhm= red , red, red . if someone could messure his OEM plug with a Ohm meter , so we could know it for sure. a wrong resistor value could result in power loss (logic). also , the resistor should be connected to the right connections in the plug.
Just had my 630 on the dyno. Power up kit and standard exhaust, no other mods. 53 PS at the wheel and like 7 PS loss. I`ll scan in the dyno chart later and will do another dyno with an aftermarket exhaust.
I assume because you're in Germany the dyno was calculating horsepower to DIN standards correct? Hence the 7 PS (aka HP) loss calculation to the wheel? And for clarification all of my dyno charts are run to the SAE certified standard. So I'm very curious about the: 1) does it have the labyrinth in the airbox? 2) whats the numbers on your ECU? 3) what kind of fuel do they have in Germany? We have this E10 ethanol diluted piss they call premium fuel here in Oregon... Thats really not to far off from where mine came in at give or take a few HP due to dyno calibration/fluctuation and being on the other side of the world and all... 53HP at the wheel would be hard for me to believe for an OEM bike. But 46? Mmmm, under the right conditions I could see that. Good info
No labyrinth with E5 98 octane. I´ll check the number of the ECU.. Oh yeah and the guy at the Husky shop said he made some kind of "update" after installing the O2 sensor plug. Dunno what that exactly means
When they pull the O2 sensor they should be putting a cap on the end of the plug with a resistor in it. That tells the bike to run in a "Race Mode" and they have to do an iBeat remapping. Pretty sure anyway... No labyrinth with E5, sounds about right then. Theres another thread somewhere that has pictures of a bunch of ECU's and we're trying to figure out if there's one that is better than another. Sounds like your 630 is running about the same as mine was...
Well it was a little boring at first, but the PU kit made a big difference. It lifts the front in 1st and 2nd with the 38 sprocket, I ordered a 44 tooth sprocket anyway..
