Hi!
My name is Martin, 23y old from Norway. I’m a happy owner of this 2001 model Husaberg 650 that i bought a while ago. The engine was "rebuildt" by Taff in january 2012, 2-3 owners ago, so it sure has been a solid build and done its job. When i bought the bike, it had not been used for a while, because the only way they had managed to get it startet was to tow it by a car.
I got it home to my place, cleaned the Dellorto PHM40 and the rest of the gas system, I changed the spark plug, oil and filter - just gave it a good service and she started right up. I drove it for about 1km and suddently i noticed a high "razzle" sound from the register side. Drove home and took of the rocker-cover. I find a 53cam in bad condition, missing pices from the lobes, and a decomp mech without any spring load, just hanging loose and knocking on one of the big screw holding the sprocket to the camshaft -making the noise.
So, lately i fixed all of the problems with the engine, bought and mounted a 08 cam with updated autodecomp, cam chain, slides and tensioner, torque limiter, sprague, r6 starter, kick sledge, DVSK, clutch, valve clearance 1/6 turn, ignition timing to 6d before, and on and on and on and on, you know the drill.... - LUCKILY it started, and it sounded beautiful! YES- i fking won! Everything worked perfect, for about 2 hours, and a new "razzle" sound was noticeble, this time also from the register area.
-The nut on the balancer shaft came loose, so i checked the back of the nut and confirmed that when tighten, it will add pressure to the balancer gear and not just only the shaft itself. Locktight and 120Nm, back on the road and drove for 10min before the sound came back. Today i used the bike 2-3 hours and was going to have a look at the problem again. Drained the oil and thats when i for the first time see pices of metall in the oil filter and the oil lt self. Not just small, but i found 3 or 4 big pices *5x20mm ish, magnetic.
Question is than, could there be a shims on the balancer shaft, inside the engine, that now is gone, and thats what made the play on the shaft?
The crank axial float is 1,1mm
Maybe someone out there have any idea what will be the best outcome? Thanks for any input! Cheers!
