watch this fool swap a '96 900ss engine into an '01 M750

[Rudemouthsky]

Really bummed that my 750 belt covers won't swap over. I'd just painted them an they look like 2 monstrous metal penises. The ones on the SS are plastic junk.

I thnk you CAN get them to swap over, but don't hold me to this.

I saw someone had done a diagonal slash-cut at the center of the belt covers, and then spaced them out... yes the covers are techincally open at that point...
looked pretty trick too.

can't remember if he did it to fit smaller covers on a bigger motor, or if he just did it for aesthetics.
maybe someone else knows....

The cut was in a semi-S shape and it was for that exact reason:  Can't fit the 750 covers onto a 900 b/c the 900 has taller cylinder heads.

Guys' name is Gil.  He's (mostly) off the board now.

Ok...lots of distractions in my life as of late. Almost ready...

Here is the engine when I first uncrated it;








Here it is now:

That looks amazing!

Great job

 OOOOOOOOOOOOOOOOOO!

Thank you! I honestly never thought I'd even have the nerve to get this far. People on this tech forum have been so awesome about answering my dumb questions and so many answers are already contained within the archives of this site, its just great. Only thing that sucks is the rest of my bike looks so tired compared to this engine. Every cruddy nut and bolt is going to be an eyesore when this is in.

Duuuude!!!!  WoooooW   nice work!

Ok so the big day is tomorrow, I have my talented friend at my disposal from dawn till dusk. I have a few questions ahead of time and will be photographing throughout and documenting all day tomorrow...hopefully won't need to stop to post here, but if you could keep an eye on this thread tomorrow in case I get stuck I'd really appreciate it.



First off, the 2 hoses coming from the carbs disintegrated when I went to detach them. Leaving nothing but 1 spring and the 2 plastic boxes. What's the deal with these? can I scrap them completely when I mount the FCR's? or will I need to route new hoses somewhere else? I see nothing on my new FCR carbs that appears to accomadate them, I have no idea what purpose they serve, and I'm hoping I can ditch them completely.


Here's my old ignitor boxes. My Ignitech appears to have 2 each identical male/female connections.


Hook it up, find a safe place to secure it, and it'll work just like that? the stock Ducati/Kokusan map is pre-installed.

My last question pertains to the crankcase breather. Should I save the plumbing and vent the crankcase back into the airbox as it is now, or leave the K&N setup currently on the 900 motor? I kind of dig the idea of hooking up pods and building a battery box at some point at some point to show off the sexy FCR's a lil' more.

thanks so much for your help. One thing I never found when I first joined this forum was a detailed, picture filled write up of this mod, and I hope to enshrine that here. I think noob M750 owners everywhere will be very interested in it.

You'll love how the FCRs clean up a bunch of redundant hoses like that. FCRs dont have or need them. Just a fuel line and an overflow hose.

Ignitech is plug and play. You need to remap for hi comp pistons. Some adjust maps for smoothness or easier starting, but the canned map is an improvement on a stock motor by all accounts. Mine is in the battery box next to a small case battery (Lithium), but some AGM batteries leave enough room. Use thin foam to insulate vibration. You must run resistor spark plugs to protect the unit.

Good luck.

Ooooh so I can chuck them in the same box as those ridiculous turn signals..chopped tail..beer tray..side panels..airbox lid...etc. Woohoo!

"Left side"
Ignitech 2-wire white plug (blue and brown wires) connects to red/white trigger wire.
White plug with white wire to black/brown/red on bike harness.

"Right side"
2-wire black plug (blue and yellow wires) goes to black/yellow trigger wires.
3-wire black plug to red/gray/black on bike harness.

Thanks Speeddog!

So here's some news: 1996 900ss inlet manifolds are the exact same size as 2001 m750 inlet manifolds.

[Rudemouthsky]

I'm completely stuck. The 10mm bolts I ordered from a 90s SS are too short. Threaded rods are currently holding the engine in place until I can figure out a solution. Apparently pre 2001 Ducatis have different item numbers for each motor mount bolt. The lengths of these bolts are not the same they are too short. All of the homework I did preparing did not warn me of this. I'm stuck with either going to a Fastenal or some other kind of industrial fastener place to find a suitable bolt, getting raped on the Nichols bolts, or drilling out the cases. This pretty much fukn blows.
