Don't know any great quotes from Sir Royce or even Confusion says stuff.....well, there is the one about " He who go to bed with ichy butt will wake with stinky finger in morning". Seriously what I had in mind was one of Kevin Camerons quotes" All too often driveability issues are blamed on the carburator and only when exhaustive rejetting fails to correct the problem will the tuner finally look towards the real problem....the ignition." Don't know if this applies here or not...just food for thought.

now i know that a 160MJ was fitted i am doubtful that my request can be right. i was very, very specific about what you had to do i think you'll agree. and you didn't do it.

the way i look at it, even if i was wrong-why didn't you try it? i think you said it was better after you dropped the needle ONCE.

i've got a dog a bit like you but i can train him for what he does wrong!

Don't tell me that, I have too many Italian bikes. I though I got rid of my woes when I sold the Spanish bikes from my youth. Those #$%#$# things had every ailment from jock itch to VD.

Now Taffy, I think you may need to direct your suggestions to the fine folks in Sweeden that produce this hitech machine. They could possibly use some help in resolving problems like this? Don't forget, this unit is brand new. It's really Husaberg's problem to make it run right.

I have a very close relationship with the dealership where I purchased this highly rated dirt bike on steroids. I was happy to do the work on the bike but only at the direction of the dealer. I would not dare start trying things on my own as it may give the Sweedish Boys a reason to void the warranty? I did all I thought I should, without changing the carb. I suggested changing the carb to my dealer and he said just bring it in and let them figure it out. I am fairly certain they will simply take a carb off a new bike, install it on my bike and call it a day? We'll see?

Considering the amount of money one has to cough up for one of these over rated beasts, it should at least run correctly when it's new? Don't you think? :)

Damn Taffy, it doesn't take much to get your panties in a wad.

My appologies if I offended you in any way.

I thought this post was a simple way of being derogatory? So I nipped just slightly back and you didn't take it very well. Again, my appologies. I am new here and I know better. I am very appreciative of your input.

I was merely pointing out in my post that the unit was brand new with a 12 month warranty and I was done working on it. It's Husabergs problem. If they can't fix it, then give me another unit or a refund, whichever they choose.

Again, thank you for your input. I will post an update once the problem is resolved. I was at the dealership yesterday and hopefully they will get to it today?

As far as the Main Jet goes, this is the first husaberg I have ever seen up close and I had no idea what MJ was in the carb until husaberg said change the MJ from 160 to a 175? I would have certainly shared that info had I known.
 
Hi TufBusa,
Your candor is admirable and appreciated.
Please do keep us posted.

Best Regards,
Dale
 
Please let us know which jetting number changes the dealer makes to make your bike run right.

The next time you fiddle with the carb try to change only one item at a time between tests. This helps us better diagnose what might be going on.

I had hoped that when you found going from a 45PJ to a 48PJ made things worse you would have tried a 42PJ next. Jetting changes can be frustrating at times but with a little trial and error positive results can usually be made.

Don't worry, your "over-rated" bike will be running like a champ very soon. Maybe you will even change your opinion to it being an "under-rated" bike.
 
You guys are great! Thanks!

I stopped in this afternoon at the dealership. The mechanic had my berg all back together and this is what he found. By the way, this guy is pretty sharpe at his trade.

One of the problems was the fuel sensor was way out of time. He adjusted it properly.

He called Husaberg and after a lengthy conversation, berg is sending us a different needle. The stock needle is a "OBEKR" I'm not sure which needle they are sending but it has a different taper. Berg says to install the needle, clip spot number 4 and set the fuel screw to turns out. It was set from the factory at one third turn out.

One of the employees has a 650 just like mine and I took it out for a ride to see how it ran in comparison to mine. It had the very same stumble, just not as severe.

I'll keep you posted as to what happens when we change the needle.

Thanks again for everyone's input.

Fuel sensor out of time? I'm not familiar with that one.

The fuel screw only being 1/3 turns out is a ****oo. Sorry none of us thought to mention a look at that. Normally the fuel screw is 2 turns out.

Sounds like your dealer is taking care of biz and you should be all fixed up soon.

Excerpt from the first page of this thread:
Pay attention experts and you may learn something. Light load high rpm provides excessive advance.

How much is too much you ask? Such depends on many variables including jetting. However, 50 degrees plus is possible under certain conditions .

Excerpt from the second page of this thread:
Just for fun I should point out that I was quite serious regarding the possibility of excessive ignition advance during light load cruise.

You automotive technicians know what happens with excessive light load advance, indeed, irregular running and consequent surge.

The Kokusan uses TPS as an indication of engine load. Under light load ignition advance does increase considerably.

"Do you suppose every TPS is in the exact same position regarding throttle opening and engine rpm? I doubt it".

In any event, disconnecting the TPS will eliminate load based advance and as stated earlier often does improve performance albeit @ the expense of economy.

Simply disconnect the three wire TPS. Mileage will decrease, however, manners most often improve.

What part did you not understand?

OK, so when Tufbusa said Fuel Sensor he was actually referring to the Throttle Position Sensor (TPS).

Thanks again to DL for his megalomania tainted explaination.

Careful Robbie as you are teetering near the personal insult line.

Regarding narcissistic behavior:
perhaps you should review whom has been of benefit, myself, or the Husaberg community.

With little understanding of load based advance:

Is it primarily designed to improve performance or just alleviate an undesirable running condition during periods of heavy load?

If the engine is in an unloaded state why would the TPS be on? (in TufBusas case)

If the engine is in an already good state of tune what effect will disconnecting the TPS produce?

Would higher octane (race) fuel help if the TPS is causing mild surging?

Thanks,
Eric

Hi Eric,

TPS load based advance is akin to that of pre engine management vacuum advance systems and as such very much mileage related.
ie Light load = increased advance.

Unloaded conditions can often benefit from increased ignition advance. Take a peak @ any 3D EMS ignition map.

The TPS is not a switch. Such is a variable resistor and represents an infinite number of values between closed (often .5 volts) and wide open (often 4.5 - 5.0 volts) throttle.

When the air fuel ratio is near optimum less advance is required.
ie Lean and rich of optimum requires more advance.

Octane rating is not usually an issue under light load.

One may simply eliminate the TPS advance during carburetor tuning and then adjust for best economy and / or performance (over a very narrow range) with location.

Vortex ignition systems allow the entire advance curve to be altered providing one has purchased the software license.

Hope this helps.

Sincerely,
Dale
 
Take a chill pill Dale.

You might not think so but I value some the info you have to offer. In fact I value the info and feedback from all of our UHE members. No one here is any more or less indispensable, invaluable or beneficial of a UHE member and believe it or not that includes you.

The UHE member community will continue to benefit from this forum with or without your alleged pearls of wisdom. I for one hope you choose to stay and share your knoweledge. My only wish is for you to dispense with the patronizing, know-it-all and gotta have the last word tone.

If you find these words insulting, sorry but so be it.

Robbie,
Truth be told I could care no less what you personally wish.

In my opinion if you do not like what I have to say and / or how I say it, simply change the channel.

I have been careful not to step over into the personal realm, I strongly suggest you do the same.

Your technical opinions are fine, make it personal and we shall indeed have a problem.

As for me, I am not going anywhere in particularly as a result of the likes of you.

Tuning is how I make my living. Such being said I share over three decades of experience via this site for free. I do so as I am the US link between what was and what is Husaberg. My theory, what good is such experience if no one benefits. In my opinion I have earned the right to be confident.

Please feel free to disagree, state your technical opinion and / or argue points of interest as I truly enjoy a good debate. However, be advised to steer clear of comments regarding personal character as such is simply unacceptable behavior.

Dale
 
HEY LOOK EVERYBODY, A PUPPY! 8O
(while everyone else looks, we install one of Dale's carb kits and move on........) :wink:
 
let us ALL think wisely about how we say things and not just what we say. we can't all see our smiles and our laughter...

having just bitten a newbies arse for summink i tend to lose my way a bit sometimes and then it gets harder for others to join in and offer their newbie-r input. i'm aware i do it but it often doesn't register on my own radar. i can't see it. a lesson for me..

regards

Taffy
