This isnt going to be anything new, just my reflections on trying a fairly well established concept to get power out of the 570 70 degreer, not saying it will work, but I set my mind to try it out, and that is perhaps the proper description here :) Bike is a 2009 570FE and is used mainly for...

Hello husaberg riders, Last time i went riding my husaberg was peeing oil all over the place. I found out that a piece of my engine block has snapped off. All this was caused by a bolt from the camchain slide that has got out of the threads and been making this hole in the engine case. Only...

Hi, I have been searching all over the internet for information on the max engine speed for my 2010 FE390. The manual only says to not exceed 7K rpm in the first 3 service hours. Other than that, nothing. The reason I am looking for the max engine speed is so that I can figure out what my...

hello! I have a husaberg fe 400 2000 model. I bought it 3 months ago, it has been running really well since, and I love the bike. However when I was changing oil I found a lot of metal in the oil screen. At the top the cam is worn out and the cam follower bearing is totally gone. cam chain looks...

Hello husaberg forums, I accidentally dropped my water pump impeller pin into my water pump today and it fell all the way into my engine block. I tried using magnets and shaking the bike, it didnt fall out.. Any suggestions? Bike is a Husaberg FS650e from 2006.

My FS570 has 10,000kms on the engine now and was always a bit of a rattler which from what i read and am told by the dealer is normal. I fitted a DJH tensioner to try quieten it down a bit which did help a little but i still think its noisy when riding it using my MX helmet..i don't hear...

2004 FE450 engine damage My bike is 50h after rebuild. Start after first kick, don't smoke, runs great. Today I opened the engine to replace cases (because they broke) and I see this: My question is why? All engine bearings look like new. The lack of any other damage. Only many aluminum...

Hello, I am going to try to take some preventative measures to save the engine gaskets (just in case I need to tear into the engine again in the future, the gasket may not be destroyed). I have loctite 518 and copper sealant (for around the exhaust). Would either of these work? Any other...

Hi all, I currently have a FE390, and I'm looking for a 2 stroke to add to the stable. I've been looking at the KTM EXC 250, just because they are so easy to find, but I have stumbled across a 2012 Husaberg TE250. I was just wondering, does the 2012 TE250 share the same engine and gearbox as...

I'm interested in reading books about fourstoke engines in general. From the carburetor to the tip of the exhaust, can you guys link some reading for me?

Hello Guys once again I have to ask you for help and advice regarding my Husaberg 501 '97. Engine is now after a nearly coplete rebuilt but it did not start at all. Seems to be an issue either with parts or set up. It kicks back while using kickstarter and does not start. The obvious...

A while back, someone posted this thesis which I finally had a chance to read. It was very well done by a student who took an FE570 engine and optimized the intake. Page 67 shows the improvement of his tuned intake vs. stock and page 62 shows the effect of varying the lengths of the intake...

I've got this copy of 1999 engine repair / service manual i think that will be helpful for all pre2000 bergs owners if they don't have one yet looking for 1998 owners manual- there is no manual for 98 on husaberg.com- let me know if you own a copy ;)

Hi, I had problem with my bike. When I bought it after few rides, when I changed the engine oil I found a piece of gear tooth. It was tooth from primary gear. Wright now after 40mth I found next piece of tooth in oil. This time is from gear from balancer shaft. Why is it happened...

Hey! I got the front engine mounts a little cracked on the 650. I got a shop to make new ones, they made it from some kind of hardened steel, a bit harder than ordinary steel they said. Could harder material make issues like making their surroundings wear more than with the original...

Hello I fixed my bogging issue with larger iddle jet and adjust fuel screw. Anyway my bike is at about 200hours and full stock not changed anything before. I wonder how is my bike's engine sound and what do i have to do? I read some topics on forum and it is about attention to...

Hi I recently bought a husaberg 350fe 1993 And I want to change engine oil before driving, So I wonder witch engine oil should I buy? Thanks for reply! Sorry if the English is bad ! I'm from Sweden, But I hope I made me understand :)

Hi all, I'm totally new to 4T engines, and recently acquired a 2009 FE 450. It had that knocking sound at low rpm, and after a bit of research it all pointed to a faulty cam chain tensioner. I replaced the cam chain tensioner with a new OEM one, and I did the trick of compressing it with two...
