i bought an unfinished project, and its almost finished. little electrical problems left and charging relay problems. but fully build engine with busa rods and 78mm pistons from an modern endurance racer. fully ported chims head that i thought was on standard cams but found out it had mild race cams. it rolled 111.5kw at the wheel on the lowest pull. that was with 36mm carbs. so hoping for alot more with 40´s or 42´s and mappable ignition. i redlined at 11950rpm according to the dyno. only showed 12300 on the tacho actually. i saw an 750 1989 article where the tacho showed 1000rpm too little. so its probably how well the tacho was made. lucky or not kind of thing
