Why don't they just go to buckets with shims,
and run the cams directly over the valves?
This is still the most trouble free system.
I would also like easier access to the carb.
In enduro situations the ability to service various
areas of the machine is necessary.All 4strokes
suffer some in this area.
Less weight is nice but not at the exspence of
durability.Oh and could they make it a little more
water resistant?

When Husaberg came out it was unique because it was a light weight four-stroke that gave up little to nothing on a two stroke in terrain that favored lighter bikes. Actually Husky started it with the te510, but Cagiva put it on a high calorie diet and bulked the bike up considerably when making the te610. Anyway, the 'berg was special because it was light and handled well in tight woods and in rough terrain and could hang with a two-stroke most everywhere and was better at some things. The 'berg has continued to gain weight and become a do-it-all 4-stroke. The Japanese and KTM are now making pretty light 4T, but 'berg seems to be heading in the direction of CCM and ATK, except hthat nothing handles like a 'berg. Even VOR saw that making a counterbalanced e-start motor with an oil pump was unfavorable to racers and has put the basic lightweight mx motor in the enduro chassis for racers. If 'berg was thinking they would buld a bike similar in weight to a yzf or crf and add lights to it, then you one again have a bike that is back to it's roots. BTW, I have wondered about the weight that CW listed the fe450 at, my bike when weighed on a bathroom scale was 10-12 lbs heavier than my buddies Husky wr250 and GasGas ec250. Each bike had ~1 gal of fuel, the 'berg weighed 250 lbs.

Hi Tjet,

My two cents on your comments:

First of all the bucket and shim thing is fine if one has all the shims and know how to set that system up. I personally prefer the rocker arm set up, as it is easy to adjust the valves, and does not require me to remove the cover, and the cam to adjust valves.

And of all the high performance, and for that matter lower performance four strokes, I find my Berg (01 501E) to be the easiest by far to get to the carb: One bolt to remove the seat, two bolts to remove the fuel tank, loosen two hose clamps, remove two slide cover screws and pull out slide and carb. I can have my carb out of my bike in less than 10 minutes. And this is on a model with electric start. The FC's would be even easier.

Most people that I race with often comment on the simplicity of the Berg.

I do definitely agree with making them a bit more water resistant, and it appears to me that has been accomplished with the 2004 models. The only place I have had an issue with water has been the stator area. I just make sure that everytime I wash it I take off the cover and blow it out.

On my two strokes I just loosen the clamps
and pop the carb over sideways.I can rejet
and service most of the carb from there.
Shims are a little harder to service but you
would probably only have to do it once a year.
And you would NEVER have to buy rocker bearings
or rockers.And they are lighter.

This thread is out of control so it's time for me to do my part.

T-jet, you are saying the crf's and yzf's only need valve lash servicing "probably only once a year"? Good luck

On your 96 KTM 300 exc you say you don't need to remove the seat and tank to service the carb? Wow, on my 97 KTM 300exc I certainly had to remove these items so again I say Good luck(Well, at least to move clip on the needle). Not sure what it is like getting to the carb on a crf but it sure looks like that damned frame is in the way of many service areas. The Berg's carb is easy to get to.

Not trying to get too personal here T-jet but I'd say 90% of your recent posts have some fairly negative overtones and I must say, IT'S GETTING OLD! Maybe it's time to get yerself one of them there KTM 525's. Nuttin ever goes wrong wi dem! Ther perfect!

Man has this thread started some bickering and arguing.

We all want to see husaberg prevail, I believe in the end it will.

Arguing will not solve anything more than simply serving as a form of venting! :evil:

Besides I see no reference to CRF's and YZF's in the previous post

That was my point 3 pages earlier.

So much whining is doing more damage to the image of Husaberg than a bad shoot out article.

Then don't post to the thread. The sooner it becomes inactive, the sooner it will disappear.

thanks,

Hi T-jet,
If you think working on a Husaberg is a pain, try working on one of the other modern four-strokes. My Husaberg is the most friendly four-stroke I have encountered. I saw your similar post over on KTMtalk. I would not recommend buying a KTM RFS, if you like easy maintenance. I was so spoiled by my Berg, I did not realize it, until I had to do KTM maintenance. I was so aggravated, I would of returned it back to the dealer for a refund, if I could have. As an example, many KTM people drain their radiators inorder to remove one, just so they can adjust the valves. The recommended KTM valve check interval is every 15 hours.

Your valve critique makes an excellent point. I too wish they were built differently, so adjustments would not have to be so frequent. But, I do not care for shim and bucket systems, personally (for the same reasons that were already mentioned). Interestingly enough, Dale can modify the Berg valve system, to where it can be just as reliable as the shim and bucket approach. If I remember correctly, he told me that he only had to adjust their valves twice, for a whole season of flat track racing. I was extremely impressed, once he explained the degree of stress that type of racing inflicts upon an engine, which from what I can tell, is unmatched by any other common motorcycle racing discipline. Apparently, there was something about a, "Good enough for world champion, good enough for you," mentality that kept Husaberg from embracing the improvements.

certainly mucking with the keihin i can get to all parts of the carb from underneath having twisted the carb over. however, i like the clips on topo and i find it easy with yamaha fuel pipes and no clips to do work with the tank off. if i had a longer inlet rubber i'd be tempted to work on it with the tank on but the berg rubber is about 5-8mm short.

the biggest hassle is the overflow pipes and their routing. this should be overcome in the next hour or so as i'm jacking the battery box up a bit.

easily the biggest worry i ever have is the fact that the carb is about 5mm from the positive terminal on the solenoid/starter!!!!!!!

i'm not so much a mechanic as a bomb disposal expert and the slightest-wrong-move-and-i'll-be
