  1. Besser kurbelwelle für die 650.

    The 2016-look! Skickat från min sk smartphone med pilligt tangentbord och irriterande spellcheck.
  2. Besser kurbelwelle für die 650.

    Steel sleeves to be mounted in the crank cases to make new 22206-bearings fit. Skickat från min sk smartphone med pilligt tangentbord och irriterande spellcheck.

    Have a look at: https://m.youtube.com/user/Massegossen ... if you are interested! Skickat från min sk smartphone med pilligt tangentbord och irriterande spellcheck.

    I have not yet started it with this latest exhausts, less done any dynoing. All that is yet to come! Thanks for cheering and sending those kind words! I haven't caught anyone licking the bike yet, but sometimes people place a chair in the pits and just sit there looking... 😀 Skickat från min sk smartphone med pilligt tangentbord och irriterande spellcheck.

    60mm. Man sollte nicht die psychologische Wirkung unterschätzen...

    In the meantime, manufactured new exhaust system.

    Well, it's not manufactured yet, but the CAD-models of the bearing steel sleeves look like this: This is the left hand side bearing mount. I will drill some holes in the flange to help secure the steel sleeve to the crank case. This is the right hand side bearing mount. The large nut will help secure the steel sleeve to the crank case.

    Cheers, folks! We did a lot of FE-simulations on the different possible crank modifications. All of them gave very small improvements. The modification I had my highest hopes for (thicker left hand side crank web), had a very small positive effect. So! That particular remedy has been put to rest. But, I will replace the main bearings instead. I will let the crank "swing free" and assemble it with spherical roller bearings (SKF 22206). The counter balancer will be removed and the left hand side bearing will be mounted in a steel bushing, placing the bearing close to the crank web. The same goes for the right hand side. I will put some pictures up, once I receive the hardware and/or get the cases machined.

    Team Dr_C is getting ready for the next race. The driver just stands there with his coffee... Thats all right. He cannot destroy so much with only one hand! ;-)

    Maybe a 80mm and a 70mm for the 550cc.
  11. The Husaberg 550 and 650 are infamous main bearing killers. The culprit is the crankshaft, because it is weak and spreads to the shape of a banana when picking up revs. I'm planning on making a tougher crank. It will require you to remove the counter balancer. The left crank web will be thicker, to be able to hold the crank pin better. The right side will have a taller shaft to accomodate a second main bearing in the flywheel compartment. A spacer/bearing cage will be mounted at the right side and then OEM flywheel/stator/cover. Crank, pin, bearing cage will probably cost 700€. I'm not doing this with any commercial interest, just fix a known problem and make fellow Husaberg enthusiasts happy! With this thread I just trying to see if there is any interest in such an improvement?
  12. Thank you very much! Thanks! Yes, it should! Preferably in a unique design! I have a girlfriendless soccer playing son at 13 years of age. No very close...
  13. This is the last video in this build project. Enjoy! [video=youtube;wd_ja-Dgx4A]
  14. Now it's time to break it in! [video=youtube;-Sex1UNB27k]
  15. The taller conrod called for a headpacker, and that was the reason for me to produce a new frame. Now my machinist wizard "Mossbergs Mekaniska" has, as allways, responded well to my emailed CAD-files. The weekend will hopefully be spent with finishing the manufacturing of a cylinder sleeve, making some fairing brackets and tidying the electric wiring.
