MOUHHAHAHAAAAAAA. I think I split my stomach laughing to much :evil: 
I didn't think that you guys reffered to "our" husaberg site as the official one....
But now I got the explanation to why I haven't gotten into it all day...

Yeah. I saw that first _after_ I had posted my first reply :? :wink:PokenH00D said:
Too bad they haven't had any proof reading done before they made the site public. There are pics of 05 mixed with text about upgrades from 03 to 04. I've emailed the guy in charge of Husaberg Scandinavia about this and volunteered to be the official proof-reader from now on. Let's see if he takes the bait.

See what you did now, the whole site is broken. :wink:
Works fine for me :wink:PowerFiend said:

Anyone know anything about the reasons for shortening the stroke from 82mm to 80mm on the 650?
This will steal 16cc from the engine and I frankly don't understand why...
Has to be some reason though.

We've been told it is to reduce the load on the main bearings. They had a few main bearings giving way, time will tell.
Hi,
I wonder if there are really so much main bearings given away that it was
necessary to reduce the stroke.
I always thought there would be more load on the connecting rod bearing.?.
The new NJ206 bearing should be
long lasting.
best regards

unless you're tuning the last 'Nth' degree out of your engine (in which case you'd re-stroke it anyway!) you'll find that you've lost no power. the engines will rev quicker and the flow characteristics are those of the bore size so you'll find that the bike is 'zippier'.
it's all in your mind.

But less torque, partiqulary unusefull in supermoto.
My bike is tuned really hard and I have problems with the left crank bearing giving up on me time after time, like 10 hours or so. A 2003 and I replace the bearings every time with the original roller ones. Are there any better ones availible or what?
And btw, can this problem be from the balancing of the crank itself? What´s the service limit for rebalancing the crank?

Don´t know. Not an expert in that field so I order them from Husaberg and put them in... If the original ones are C3 then that´s what I am using.

a standard bearing is designed to run to 10,000-11,000 rpm. but that would be with a perfectly balanced round shaft and not a crank and it's assembly.
the other thing is a standard bearing doesn't like the axial expansion-it wasn't designed to tolerate it.
a C3 bearing is an expensive bearing made to a higher specification and quality BUT it's "looser" in that it's designed to take up the slack upon expansion. in other words it's great for car and bike engines.
they're bloody expensive!
that's why you'll often find the manufacturers only put one on a camshaft and one at each end of a gearbox etc.
a C3 bearing is a must i would have thought. if you ask a bearing stockist for your std bearing, they will cross-reference you to the C3 equivelant AND give you the specification of it as well.
when rebuilding you don't change the axial tolerance from the set manufacturers. the bearing does all the work for you.
i got through 3 cranks in 1984. changed oil, changed bearings and never had any trouble again.
this will be your problem and NOT the balancing!

C3 designation is merely a internal tolerance specification telling you it's greater than normal, not necessarily that it is better quality or a higher specification bearing in terms of materials etc.
The standard roller mains used in the Husabergs were, to begin with, C4 designation which tells you it has an internal tolerance greater than that of the C3, which I suppose means it is "looser".
The roller bearings are very hardy little things anyway so if you're having constant trouble with them, I would recommend you check the crank alignment/end float although up to about 4 degrees of the arc your standard roller bearings should be fine.
I know this isn't really an answer but it is a bit of anorak speak.... :wink:
Cheers,

PS the SKF speed limit for the 6206 roller bearing is actually listed as 15000rpm now.
