I use the same method on twins too especially on the 850 Commando, no valve lifter so you stand on the kickstart and let the compression leak away until TDC.
Dido that for the 850 Commando
! I don't weigh enough to kick it any other way. I have to stand on it for a moment before it will move past TDC and then quickly stop the kick arm and allow it to return to the top of its stroke. Make sure the carbs are tickled and choke is on. Then it's one of those bucking bronco kicks to get it to make it past TDC on the other piston. Luckily, it starts after a couple of attempts.
FWIW, I have two B44s, two B50s, and a B25/TR25 and they all start easily cold with the above mentioned methods. But always need to turn the throttle stop screw in one full turn before kicking. Back it out as the revs climb.
