Monster Emissions Cannister Removal

[ducatiz]

So, is  anyone of you look at your spark plug's after you did the modification???

 .   Because on a carburated one ...if you take out the PCV system ( the canister) there's less vacuum in the crankcase and the toxic fumes from the "blow-by "of the cylinder cannot be vacuum out of it.
 
 If  you take out the "canister" ,  you take out 4 in Hg of vacuum that the "canister" was doing in the crankcase.  Toxic fumes from the "blow-by" built up in the crankcase and build up pressure in it so all those fumes go back up past the blow-by and return to the combustion chamber ...and there you have it.... spark plugs carbonised by an excess of toxic fumes in combustion chamber.....( so now your must be thinking the carburetor is set on a to rich mixture.... )

I f you do the mod you absolutely need to restore that vacuum by placing a K&N filter at the crankcase vent or the tube that is left there after removing the canister.....


the same principal apply to the airbox don't block the vent!!! no vacuum will be produce...

You know they just don't put those just to make it ugly ...those things have a purpose...

You don't understand what this thread is about.  The emissions canister referred to is the "evaporative emissions" charcoal canister which is ONLY present on US-bikes and ONLY added by Ducati to be California legal.  The canister is not used on any Ducati (or any other) motorcycles outside the USA.

This is not in any way related to the PCV.

I can't really tell from the photos, but assuming the 'bulge' is removed with the cannister gone, are there any flat (e.g. non-bulging) side-fairings available for Monsters? It would be nice to have a smooth, flat one like on the left side.

yes you can buy it from motorwheels
or any european dealer.

To elucidate, the non-US versions do not have the charcoal canister.  You can order the European part from the catalogue, just specify the European version in the order.

Does anyone have any pictures of the removal process of the emissions cannister?

it's two or three small bolts to take the canister off and then plug up the nozzles on the manifolds or remove the nozzles and put in screws.

I've just performed this on a CA model 2001 Monster 750, and have a question:

What are these grey plastic triangular cans for on both sides of the bike, and is it OK to remove them as part of the emissions junk removal ?

I've just performed this on a CA model 2001 Monster 750, and have a couple of questions:

1 - What are these grey plastic triangular cans for on both sides of the bike:



2 - What is this aluminum valve type device:



3 - Should all these things also be removed ?

you want to remove the carburetors and fuel pump?

I removed a device that looked a lot like that from my WR450 which was part of the emissions junk, that's why I asked.

Can you can tell me about the two triangular cans ?

those are just covers . . .

They are not covers, they have two what look like breather tubes going into them. You can just see them in the pic, going into the 'tank' on the left side.

You can remove the plastic pods if you like, run the hoses that go to them where the air is still, like behind the battery box or you might have running problems.  Those lines are from the float bows and above the diaphragms.  The pentagon shaped thingy is your fuel pump.  You need that.

Thanks.

Yes, I investigated the plumbing and discovered that myself.
It must be a vacuum pump?
I'm used to fuel pumps having a 12v electrical supply, that's why I initially assumed it was part of the emissions crap .
