Hi guys this thread gos with the hayabusa b king conversion but iv taken it a bit further, fell in love with the Rad Greeves extreme busa in your AMA, so iv decided to follow that up with a little twist, iv gone for the 1400cc high comp bigbore with ported and flowed head, epoxy welded the inlets and exits on our flow bench, converted the head to Ti valves with the lighter spings, bespoke cams firing cyl 1+4 together then 2+3, souinds like a proper motogp bike, developed with a local motorsports engineer and kit ECU and loom to run and data log the engine and rider info, cam chain conversion along with stronger studs, converted the swingarm back to stock but filled it up with 3mm ali then linished it back to nice finish (see photo) made some wheel adjusters and paddock stand bobbins that fit the standard swingarm, converted the rear wheel to take a rsvr dymag wheel and got rid of the suzuki rear brake caliper and converted it to a slider type from within the swingarm, gsxr radial forks with rsvr dtmags and brembo discs all over... more to come in the next few weeks, just starting on the exhaust system to accomadate the big bang firing order.. pulse width etc... all the best john.

sounds interesting. who's ecu are you using and what are you don't for the ignition system? I guess a wasted spark system would work well for your app.
