knocking

I just finished rebuilding the bottom end of my 2006 FE650. The auto decompression stopper (hot rivet) backed out and snapped my cam chain. Damage wasn't too terrible, but I ended up addressing the flooding wore items: replating the cylinder, new Wossner piston, complete rod kit, both main...

So I've got an 2006 FE650E. It's been pretty nosey since I got it last fall. Has 200hrs on the clock. I know they're a noisy motor, but this is a bit noisier than my RFS KTM. I just installed Taffy's Dual Valve Spring Kit, along with a new cam chain and tensioner. Figured that would have...

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...

My fe 400 has developed quite a loud knocking, it started quite suddenly so I stopped riding it and I'm using my other bike for now. I've recently stripped the casings as I had a problem with the camshaft beairings collapsing, it rode fine for a few weeks after that, now it's started knocking...

Hi everyone, We have been racing husabergs in enduro sidecars since 2005 and have had our share of problems but now we have a new one. We recently had an engine rebuilt and running well for three days racing before being taken out to save for the main race of the year. When we put it back in...

I had a bad experience with my 390 berg hit a rock or something hard. The really bad part is that i didn't noticed it before i began to hear a knocking sound from it. It was a hole in the clutch cover and the oil had dissaper. After a new clutch cover and a service of the berg i started the...
