robertaccio 406 Posted May 25, 2022 some motivation for the final look is already complete. It just keeps me focused on the end game. head is in work and engine is on the engine stand. FYI Spec sheet for mid nineties Husaberg FC501 @55bhp at 8000 RPM, under 230 Lbs. 1 Share this post Link to post Share on other sites

Bottom side Looks lower than carb Husaberg engineers copied the Honda factory works RC500 tank set up and worked with Acerbis to create an OEM low boy tank. What you don't see is a outer tank mounted Mikuni vacuum fuel pump that constantly pumps fuel to the higher petcock side of the tank. As long as the bike is running this pump is circulating fuel to the high side whether needed or not. Good observation. Share this post Link to post Share on other sites

As weird as the machine is.....spec sheet doesn't lie, single cam, 4 valve, less than 230lbs, @ 55 Hp. With a few World Championships under it's belt before the so called AMA US centric Japanese 4 stroke craze began. Share this post Link to post Share on other sites
tntmo 887 Posted May 26, 2022 They are interesting, but in my opinion if they were “all that” they would still be around. Cool machine anyway, let’s see how it gets transformed into a beauty! 1 Share this post Link to post Share on other sites

Cool machine anyway, let’s see how it gets transformed into a beauty! KTM bought them out and created their now famous single cam RFS line directly based upon the Husaberg design, that 'Berg DNA can still be found in all those RFS KTMs that are still out on the trail to this day. The other side of that evolutionary tree went from the original Swede Husqvarna 4T design to the Cagiva owned Husqvarna Italy all the way through the 350/410/610/630 (570 etc) line of big single cammers. ( my 1999 TE610 is on that branch). Incidently the Husaberg design is brought in from the same engineers that designed the original Husqvarna 4T in the mid 80s. I'm happy to report that both my Husaberg 501 and Husqvarna 610 are later model oil pump equipped machines. Share this post Link to post Share on other sites

EBay and the mighty Taffmeisters in the UK for all sorts of stuff as well as full email tech dialogue . Lots of parts around. typically they did not change much for the entire decade . I have brought in the engine stand to my sponsor shop NCM.net and my chassis is getting closer for assembly. bits and bits. https://www.taffmeisters.co.uk/index.php?cPath=232 Edited December 18, 2022 by robertaccio Share this post Link to post Share on other sites
