OOOO K,pash here we go lightend crank to help grumbly spin up quicker
..........non permnant magnet altinater .this WILL ade cranking,as there is some effort needed / power lost just overcomeing the permanat magnet altinator
valve spring pressure saps power,slows engine spin up time ,so the lighter the better ,hence reducing valve train weight ,lifters FAR too heavy ...nick adjustable push rods will be heaveier than STD ones without oil in them ....the top end is feed oil through the lifters then the push rods (how much do they weight full of oil
),..497 cams give FAB torque from 3500 in grumbly 2 with a 1200 motor so were hopefull they will work WELL in a 984 motor ,........lubricating the top end via the scavenge side of the pump,BSA have done this for years ,......now the oil thats no longer needed to lube the top end from the pump can now be used to feed the big end via opening the restriction up in the end of the crank / lower running temp in the big end as MORE oil is flowing through it
the grey area is the oil jets inside the crank cases fireing oil to the underside of the pistons ....oooa it might all go badly wrong
...its all very exciting
,there will not be that many pics sadly and this will take a LOT o time to come together

, and if weight or power to weight is an issue when are you going on a diet 
......exactly how you're gonna do this is beyond me as you'd at least have to fit a restrictor into the circuit to get enough 'pressure'/flow to feed the rocker bushes......Buells have enough issues scavenging their sump, heads and camcase as it is without return oil being cycled back into the cases before they've made it to the tank 
.....We know it must be the time of the month.
