A mountainbike racers quarantine m900s rebuild thread. what could go wrong...

[rsoffar]

bummer, the hydraulic gear puller I was able to snag is too large to get a grip on the primary drive gear.

[Speeddog]

I will admit. Im currently stuck on the primary drive gear.
~~~SNIP~~~

Access to the edge of the gear is limited by the crankcases.

OEM Ducati tool is shaped to use all of the space.

I'd recommend using the OEM tool.

[rsoffar]

have one located. Hopefully can have an update in here sooner than later

‘00 900S with the floating rear caliper hanger, OE Öhlins rear shock.  Nice.  The 10mm engine mounting bolts aren’t great, but Nichols makes Titanium replacements.  Nice Nichols breather & 48T slipper clutch.

If it were my bike, high compression pistons would be in order and some fork internals...

[koko64]

+1 on that.

Perfect project for cabin fever.

What condition were the cylinders? Saddle?

Look up eBay for CCW heavy duty studs, they are about. Powerbarn are selling JE high comp pistons for a good price.

The stock loom is such a mess on this model as it travels over, under and around the air box. Corse Dynamics intake kit with cut down battery box opens up wiring options. That being said the air box has better volume than some models and with modifications and a PCIII can work well.

oh wow thanks yall.

I knew it wouldn't take long for this thread to get talking dirty to me.
I had not considered this mod but when's the next time Ill be this far into things. Not crazy expensive either  

what kind of other mods does upgrading to these pistons require? any Dif fuel mapping or anything to go along with it?

If you are going the heavy modification route do consider making your own harness.  There are a few threads about making one on this forum.  Not so bad on a carbie.  I couldn't agree more with koko64 about the factory harness.

I will definitely be watching this thread.

this is great to hear. something I have the idea Id really like to tackle but its pretty intimidating. I have been searching the forum for all the good threads, collected a couple so far.

FYI this ones fuel injected not carbed, not sure if that changes the opinion of it being not so bad ha

[Howie]

Yes, more work, but still doable.  Lotsa pins in the connector for the ECU.

[koko64]

Just raising the compression means higher octane fuel but that's about it, all else being equal. The tuning consequences start with open airboxes or intake kits that remove and replace the air box with pods, then you have to look at Powercommanders, dynotuning or ECU reflashing. Unfortunately, removing the air box, or cutting it off the battery holder, frees up how you can reroute and tidy up the loom in that area without chopping it up. It's the worst part of the loom on that model imo. The easier path of tidying up rather than cutting up the loom is much easier with the air box gone or modified. My brother and I considered a separate airbox to battery/ignition holder made from two whole components in order to reroute the loom and make servicing easier, quicker (and cheaper). This would keep the airbox operating with its benefits.
FWIW, the WASP intake kit people over here did not fit their velocity stacks and pods to your model but modified the air box and tuned it with a PCIII on a dyno. I noted that with interest. Just some food for thought.

That model, the 900ie imo, is the best of the 900 models. The motor comes with hot cams from the factory and better ports (don't make them any bigger), a bigger air box, lighter wheels (a bit), a stronger charging system and EFI. You get the S model goodies too. The motor just needs more compression and a good tune to wake up. You won't recognize the performance.

Wow so cool to hear they are still around.


Still remember buying all the parts from them back on my first experiences with my first m750

Hahaha amazingly excited when taught how to change a chain...
