It's my bike and my engine, so I don't want to pay anyone to do anything. I think I can remove the cylinders, replace the studs, fit new pistons, paint the covers, and put it all together. What will happen when I turn the key is the question, haha. All degreased and nice n' clean..here we go.

Good luck...it ain't rocket science. Go slow...pay attention to o-rings (take pics)...and ask questions before you get out the big hammer. ;)

Hey DP; maybe I shouldn't be asking you since you're a professional painter and this would disgust ya; is there an easy spray can solution for the covers and fins? I'm going to polish the block but I want the covers and fins to be black. I used self etching primer and single stage automotive paint for my 750 and (I think) they came out great. Really don't want to get too fancy with this part.

I like the process you used on the 750.  ;)

I don't do spray cans because they aren't very solvent resistant.

That said lots of people use them and are happy. The temps that the parts reach don't require super high temp materials.

Regular BBQ stuff should work fine if you can find the gloss you want.

Don't buy any engine parts until you get it open and see what's inside.

I agree. I also really wanna hear it crank...I have my old coils and a battery....is that a dumb idea?

Also, the circle stamp is 96 and it has a dry clutch. So it's not a 1991 like I originally thought

A couple of years ago I did this same project to my '92 SS.  Like DP says, it ain't rocket science and pay attention to where the small bits are.  I got a PDF of the manual that was invaluable.  I wound up with 160 mains (Factory Pro #'s) and the timing fully retarded and I can run 93 pump gas without knocking. That's not ideal but it's working. You will want to check your squish, if it's too loose that can help promote knock as well.  I haven't put on the Ignitech unit yet (going to) but that won't give you any more adjustment than is built into the timing already.

How are you going to hold it down?

all 900 motors have dry clutches.

i've checked the squish on a couple of sets of je and it's pretty good, plus the 2v motors have a taper at the edge of the piston and more on the chamber, so any contact would be on the very outer mm or so of the piston anyway.

when you lift the heads keep the cylinders down, then when you lift the cylinders have someone standing by with a vacuum cleaner to suck up the debris.  usually the studs will have lots of rust in the studs/holes that will fall off and down into the cases, lh vertical in particular.

Was there oil in the engine? If so, any nail like alu shavings in there?
Those are a sign of the loose crank plug some mentioned.

You can check f looseness w  the crank in right position and a pointy instrument.You don't have to split cases to check and knowing it is ok is good f yuor sleep.

I've got the heads off. Wanted to post a pic of shiny aluminum but this stuff is weird, its like a sand cast I don't think it'll polish?

Hey guys;

are these the good studs? they sure look like it to me...



Also-since there's no head gasket here where the cylinder head meets the jug, what does everyone recommend putting here? RTV?



Some pics of paint work for your scrutiny are next...

"aluminum" colored engine paint for the case, matte black for the covers...what do ya think?







All the fins on the jugs and cylinders are getting black as well.

I realize this isn't a professional paint job, but I'm happy with it, and I wouldn't be offended if you critiqued it.

To my untrained eye, this piston doesn't look bad? very little carbon on it either. Lots of hairline scratches, but no obvious "gouges". Thoughts?


Reasons I've decided not to use high comps: several Ducati guys who I respect don't particularly recommend them..I don't want reliability issues with this engine..don't want to be chained to high octane fuel...and most of all, I KNOW I'll be wanting to swap in a 1000 or 1100DS motor in within the next 2 years.

If you think this piston looks like junk, I can look for a low mileage used pair?
