supercharged and fuel injected cb550k. (Startup video added)
« on: March 18, 2017, 05:34:43 PM »
some pictures of my almost finished cb550k supercharged with a aisin amr500. Microsquirt fuel injection, lots and lots of custom parts.  gsxr750 front end, hayabusa discs. braced frame and swingarm, custom tank, seat, intake manifold+++
Engine is fully built, ported, cam, JE pistons.
Bike is 97% finished and got a lot of attention in the norwegian bike show last week.

Let me know what you think :)

i also have a longer build thread in the high performance section of the forum.

Would love to see some up close shots of the induction system.  Beautifully done bike, sir.

i attended Oslo Motorshow this weekend and won a award for "Best Engineering" across all classes of motorcycles :)

Quite happy with that one :D

Actually got to drive the bike a little too.. sounds amazing and feels good :D  Just some final tuning left, but the bike is finished ! :D

As ive never driven this bike before.. ever..   Its difficult to compare.. but it feels strong from down low, even with 0 tuning on the ecu.. it runs way too rich and the ignition table is not optimized yet.

Finally got to hear the sound on the video.  I can see what you mean about it running rich!  I was trying to discern the sound of the blower.  At what RPM range does it engage?

Are you running the factory charging system?  That is enough to drive the fuel injection system?
