My M750 carbie flywheel started out at 2052g, and ended up at 1726g after extending the trigger lump and a good bit of lathe work to lighten it.
I could have lightened it more, if I hadn't run out of time on the lathe I was 'borrowing'.
It's certainly not 'too light'.

I thought I weighed the Nichols unit, but I can't find that info.

IE flywheel would be easy to cut down.

A 900ie with ignitec and FCR carbs would be good I am sure. I have built a few 800ie motors running the FCR's with both oem Kokosan ignition and an ignitec so it can be done either way. I am waiting on speeddog to be the test pilot on a ignitec unit using the crank sensor pick ups, no reason it should not work great. I have just not tried one yet.

Injection would also be fine and lower maintainance just not as much fun in use. If going this route I would base it off a 5am ecu not the 15m.

I also would say gearboxes are subjective on my 900's I prefer the closer ratio gearbox which was only used in the 900 monster S models. It is an easy upgrade when building motors as it is the 748 gearbox and is pretty much a drop in. If you are running higher speeds or lots of extended time at higher speed the higher overdrive may be preferred. For track or tight twisty stuff I will take the lowered gear version.

99  is a hoop style ride height adjuster if you are running a s2r swingarm the later style frames with a superbike style rod might be an easier conversion.

But, since all but the 2002 900 engines have 10mm engine mounting bolts and the later style 'ST-based' Monster frame (which readily accepts an S*R swingarm) runs the 12mm engine mounting bolts, you'll have to deal with a conversion there.

So pick up an 02 900 wreck and fit sss as the easiest starting point. Will it be a US reg or Aussie reg Titan? In Oz the frame is the bike and determines what you can and cant do. In Oz if you want a carbed 900 it will need a carbed 900 frame to get thru. If its a US bring over, then thats another matter.

My '01 750 had 12mm. mounting bolts, not sure about '00.  99 and older were 10mm. for sure.

Ah, SpeedyMoto frame slider fitment:
Monster 900    1993-00    09-0203
Monster 600, 620, 659, 695, 696, 796, 800, 1000, 1100, S2R, S4, S4R & S4RS    2001-    09-0201

2000 and older, 10mm.

Secured an '01 900 frame. It's black, will need some serious TLC. Just going to go with a very nice gloss black. I need to try and find an engine now. Going to read back through the thread to figure out which is best for my needs.

That frame is 12mm engine bolts, so '01 and later for direct bolt-up.
