Mikunis from the Yamaha worked...but the cables coming in from the rear did not. They fouled on the tank and made the steering feel stiff. Enter Gerhard
he kindly donated a set from a Ducati so the cables came in/out from the front. Unfortunately this was not a quick fix either, as the cable bracket had very little room before the radiator cooling fan housing. The throttle was very stiff as the cables were bent as they came out, mainly the return (throttle close) cable. I removed the return cable as the spring on the carb is strong and was snapping shut. I had to use the original Paso twist grip as it has the stopper bar inside as its designed to run 1 cable only.
Also, the cooling system hoses and T piece I installed were too high and the cable bracket stopped the carb from being seated on the inlet tubes. I had to re-route hoses and modify T piece to lower whole system
The coil for the hor. cyl. was in the way too, so I had to move it forward. Make sure you remove the paint from both surfaces to get a good contact as its now only secured with one bolt.
I removed the electric fuel pump (gave to Giscard) and installed a vacuum pump in its place (Thankyou G.) I mounted it in the same spot but had to use spacers and a home made bracket.
I power the pump from the inlet tube closest to it.
I supply vacuum to digiplex from the other inlet tube.
I have the fuel line going from tank to filter to pump to T piece to carb. The other leg of T piece returns back to tank with a restrictor jet in the line. There is also an overflow line from the mikunis that goes to a little catch tank. I have also mounted another little triangular,black, plastic tank from a monster which the diaphragm breather tubes go into.
Once it was all plumbed in I started it up and went for a ride. It took a little while for it to start but that was expected. It ran ok for a km or so but then started running like a pig and then died altogether. After pushing it home (she's stretching the relationship right here) I pulled it all apart and noticed that the diaphragms were slightly too small and were not seating properly in their grooves under the black covers. Luckily the ones from the Yamaha mikunis were a little bigger and seated perfectly. The jetting set up is as follows;
Dynojet (stage 2 for 900M) Needle jets with the circlip on the 3rd rung down from the top and the nylon ring under the circlip.
Dynojet springs
75 (mikuni) Starter jets
170 DJ Main jets
45 (mikuni) Idle jets
Idle screws set at 3 turns out
Adjusted idle to 1200rpm
Installed UNI foam pod filters, put the tank and seat back on and went for another ride. Pretty much runs perfect now with this set up
There are a few little indiscretions every now and then (read; farts 
) 
but I think that's more to do with a balance issue as I only balanced by eye on the bench (made sure the butterflies were moving in sync and were at the same point at WOT) I will be making a balancer from some tubing later today and will fine tune now that I have the basics done. I have a bad oil leak which needs to be fixed before going on a long ride anyway. I have traced this to the oil pressure switch which I'll be replacing when I get back down from my next work commute in a couple of weeks.
I hope this helps anyone who is looking at doing the mikuni conversion in the future. This set up works for me. I am in Australia at sea level. You may have to play with your jetting to suit climate and altitude.
I apologize for sounding like I know what I'm talking about (coz I don't
) I am only stating the steps I took to get where I got, and managed to pull it off. Thankyou to all for your help along the way...you know who you are
