My new 2011 fe 570 only had a 90 day factory warranty so it was necessary to perform all severe stress testing immediately while still under warranty. One of the first stress tests was a series of speed runs on interstate 279 near Pittsburgh PA. The first test runs were with the stock gearing...

Has anyone had to do any work to the cylinder on their 450? I think my bike needs a top end and im concerned cylinder work will be needed. Anybody have any experience or a preference on where to get parts from?

Do the 70 degree motors make a lot of top end noise? Mine seems to have quite the valve train tic to it.

Have an 02 fe400 needing a jug and piston found this kit http://www.ktm-parts.com/80530012000.html#.UQ8lumt5mSN but looks like the pin diameter is different for the 400 also not sure on the jug is there any other options? Trying to keep costs down its a secondary bike not used a lot

I'm at 90 hours and am getting a bit of smoke when I rev up, top end might be a bit tired. Anyone done a top end yet? How much more complicated is it with the motor slanted? Any DIY out there?

racking up mileage rapidly on the new FE570. searching the forums, it looks like the later models are fairly bulletproof (after sorting out fuel pumps, filters etc) so interested to see what kind of work FE570 owners have had to do after clocking up a lot of mileage. VALVES: most riders seem to...

Hello fellow Berg owners! I am new to your forum and firstly thankyou for the wealth of information already contained here - it has saved me asking MANY questions! I am new to moto and have picked up a '09 FE450 w/ 22hrs. I now have 38.8hrs on her and decided to check the valve clearances. No...

Pretty good chance this has been brought up already.. The search engine failed to get me anywhere. I have the Forks off the bike, And the Tubes unscrewed from the Cap... The Nut that's held (inside the springs) is exposed. I understand that I need some kind of Pin wrench. I recall some one...

After having the y fitting in radiator hoses fail on my 2010 FX450 at race a couple of weeks back and seriously overheating the motor. I had some concerns about the piston, then during an enduro last weekend it started blowing coolant out the overflow. So I decided to tear it down and replace...

hi would the top n bottom yokes off a 2007 fs650 fit my 2003 fe650 thanks

Manual says 90 hrs for new piston, camshaft bearing, conrod bearing, crankshaft main bearing. Just wondering what you guys have been replacing and after how many hours. Is it really essential to do this at 90hrs. (guessing it is related to your style and type of riding). Did you guys wait...

Does anyone know where I can get the cylinder head (or really just the rockers and camshaft assembly) for a 2001 FE501? Or any compatable sets of these parts would work as I beleive these particular parts are interchangeable from like years 450, 470, and 550's right? Maybe? Specifically will...

I'm still in the break in stage, What is the top speed? Ive had only to 50. I'm sure it will go faster if I let it

I just picked up a 05 fe 550e with 48 hrs on it,all scheduled maintenance done to it,was lightly trail ridden,I've had it out twice and put 75 race miles on it,I noticed oil seaping out of the hose on the top of the head ,next to the front valve cover,the hose clamp is saturated,has anyone...

Just curious what kind of hours are you guys running before doing a top end? I am looking at a very clean fe390 that has seen the better part of the nat enduro series and lots of local races. I have an fe450 with 18hrs as of today. It is about a month old and has really proven to be a great...

I have a 99 501 kickstart only motor and was curious if it is possible to swap on a 650 jug and head? I couldnt find any specs anywhere in the doc, so I was just curious if anyone was aware of what would be needed to do this, if possible. Thanks

Hey this is my first post, I'v done a bunch of reading on other peoples problems, and now I'm looking for a little Berg help. I have a collection of 3 501 motors (91, 94, 2001) and a 350 (91), as well as a parts 350 motor. I got the 2001 with a broken cam follower bearing and i'd like to get...

I was wondering if anyone knew, what the engine horsepower and top speed for a 2000 FC501 was? I dont have a dino or speedometer. I know this bike is tall geared with six speeds. Thanks for the info

I just blew up my husaberg fc550. The bike is only ridden as a supermoto, I want some more power, any suggestions while i have the cases split? I would love to upgrade my internals across the board, but i can't seem to find any info on options? PLEASE HELP BERG FAMILY! Also can you swap...
