Title: What's good / bad about a 900ie engine?
Post by: slowkitty on February 16, 2010, 03:01:59 PM
Monster Noob here .... Rebuilding a low-mileage 900ie  ....

How good or bad is this motor? What do I need to do to it (if at all)?  Not looking for speeds above 150 km/h :)  

Appreciate the feedback.

Cheers

Why?

Did it blow up?  Strange noise?  Just like tinkering w/mechanical bits?

I've heard nothing bad about that engine in particular.

Nothing bad that I can think of. Good aggressive cams from the factory, good parts availability, and it sounds good.

give it more capacity, more comp, head work and a wide ratio gearbox.

got any money left after that let us know.

Well, if it is not broken don't fix it.  I am new to Ducati, and was just wondering if there is anything in this particular lump that I should watch out for.

Looks like a good oil change, valve clearance are needed and I'm good to go.

Thanks for the info.

Cheers

They'll go an easy 60K and have gone 120K w/o a rebuild if you treat 'em right.  Bullet-proof may not exist....but this motor is damn close.

Brad,
What fits in terms of "wide ratio" gearboxes?

TIA

As in, what motors have the wide ratio 'boxes?

Yes,  what motors have the tranys that would work?

I "believe" the only motor that had the close ratio was the "S" models of the monster. Again, I "believe" you could tell what was close/wide by looking at the front sprocket and if it was offset, it was close and if it was centered it was wide. <-- I could also be talkiing out of my ass completely as it's been so long.

Hence, why I ask the question in the first place.
