I have to check my bike came with a different almost new ignitor box, FZ has the jets in carbs from new that are power increases from FZR factory.Meaning FZR has less GRUNT than FZ. Also I fitted 64mm pipe from the 4into1 s/s header-collector and added an aprillia 706 dual outlet muffler, with the narrower section cut off the inlet making a FAT pipe straight into the can.Seemed to be extraordinary but no recorded data to support my satisfaction. I support the ‘no mirrors gain’ theory too. 44 tooth sprocket at back but too much hassle to count that front one. There is a pic of mine on Facebook / FZ750ownersclub; its painted blue/blue/blue(3 tone).

well i just did a rewire on the fz and with a lot of theory and study found it a doddle to wire up the ignition and starter.Your mechanic mate shall have it running in 2 hours. its just a solid state ign. with crank signal, igniter……usual bits.earth the coils well and the only reason for a diagram is a want of a circuit tester. coils run 1-3 & 2-4 cyl. as you may have figured. Many FZ Genesis motors wind up in buggys due to the fear factor on two wheels but its to bloody powerful and leggy for a go cart so the result is worse than m/cycle shock factor. Hammer the 4-10K rpm range with (reported by Yamaha) 105 H.P. available, it will not disappoint . Unlike its destroyer who savaged the original. There is an FZR that shares the same motor as FZ so check the engine code if it hasn’t been grinded off. 2LM is the first FZR I understand.Fz are 1FN,then a whole bunch of numbers to 2MG & 3?? not sure but you’ll find it on this site if you look about. Break a leg.
