More power in my M900 -98

[Graymonster]

Is it an idea to change my vacum fuel pump with an electric one? Would my FCR 41's like it?
(also thinking about fitting an 999 fueltank.... love the look on Radical 9 1/2 )

heads turned up yesterday..
bit disapointed, I thought they looked like they had larger valves, but they are standard.
Also, I would have thought if you spent money on a twin spark setup you would have had them ported as well...
And they have standard cams...

Oh well, not a big deal, still not a bad price for heads here in Oz. I'll probabaly clean em up re-shim and on sell!   

Sorry to hear that monsta.

You would have to manage fuel pressure to 3 psi max. I like the big ugly hex pump for its low pressure but high flow capability.

[Howie]

The stock pump flows 65 liters/ hour (about 17 gallons).  Obviously more than it needs mathematical since, at 60 MPH would equal about 3.5 MPG.  Thing is, full throttle, no vacuum.  I would think, from an electric pump, less would be needed.  See if you can find what the volume is on a carbie 900 supersport pump.

Thx howie and Tony

Started teardown today, and found that my cam belts are way to loose.... Have felt that my bike was getting more and more lazy (maby thats why) but neglected it because the soon to come rebuild.... Realy exited about the outcome of this, hope it will feel like sitting on a rocket when finished

Gray- I've got this rectangular Mikuni fuel pump w/ FCR41's on my M900. Works great still w/ 6-7k on it.

I prefer this one for the peace of mind, matches the flow rate of the OG. Probably a good idea if you have future performance mods planned. You'll need a 2-1 splitter. It mounts up same as the OG also with slight modification.

There's a problem with your links.

They don't even work if you copy and paste.

Thx guys, I,l consider one of those pumps.

Teardown time 


Cannibalizing the old exhaust




The rough idea

Did a quick scan-back, must've missed something; watcha doing with that exhaust?!?

Oh and re: fuel pump again;  you should explore going electric. The subject has come up a few times and I think either Chris Kelley or Stu or both have done it successfully without hassle, but there isn't much documented. Someone has used an electric pump from a fuelie Monster on a carby and the pressure difference was not an issue, I gotta find that thread...

[Graymonster]

Hi BN.
Here http://www.ducatimonsterforum.org/index.php?topic=68956.0 is what you missed

And this is what it looks like now

[Nibor]

Is that just straight through, or mufflered? Will look awesome with the headers cleaned up! Love something simple, light, and loud on my bike, ran it briefly. Couple of times straight out of the midpipes, it's a bit too loud then haha and I know not the best for the engine.

[Graymonster]

It is mufflered like this


The pipe also includes an additional sound supressor and silencer held in place with a snap ring. Easy to take out if you want. Loud or louder

While waiting for my heads and carbs I hacked of my rear end



The idea is to make a new rear end. A little shorter and a little higher. I'm also planning to use a 999 fueltank... And new single rearsets... Any suggestions? Cheep and black

I also want to make a new electrical harnes. It must be like 52 meters of unneccasery wires here...



Got my heads and carbs today



Very glad its like 3 degres celcius and raining here... If not I would be out driving with no rear end and a wire harnes draging....

If you want cheap single rearsets, get them from an ST2 along with the rear brake master lever and mount. Got it all for $70 and then proceeded to change the pegs out for shorter aluminum ones $80 two months later
