Ducati Monster Forum

... well, it happened last weekend. My 05 S4R suddenly died, because  Rectifier / Regulator died from overheating ...
Luckily, it happened in the area where one of my close friends lives, so I pushed the bike about a mile, to his garage ...

So, got  the new Rectifier / Regulator, and Relocator kit from TPO parts . (also, crankcase breather Vent filter kit. )
These kits from TPO parts come with detailed instruction. Probably anybody can install, but here's the review anyway.

Installing the R/R relocator kit requires the removal of crankcase breather tank (because R/R is mounted on this tank ), so, here's how things go.

The instruction paper says unplug the rectifier module, but you can do it without unplugging. Just undo three bolts, move the rectifier out of the way, loosen the clamp and you can remove the breather tank. Like this.

Breather tank removed.

Now, the crankcase breather vent filter kit instruction says remove all the hose and install the K&N filter directly on top of the breather valve. But I left the hose from breather valve (1) attached, just removed the hose between air cleaner box and breather tank (2).

This hose

The kit comes with five different size of plugs, to close the vent hose hole on air cleaner box.

Supposedly one of them should fit, but the hole on the air cleaner box of S4R is ...

... ellipse  :o not circle. What do I do ? Well, I had rubber plug in my parts bin, so ...

(http://i342.photobucket.com/albums/o420/ZX750E2/Monster/IMG_0362.jpg)

 ... just cut the hose, push the rubber plug in ( the gray thing is RTV silicone sealer)

(http://i342.photobucket.com/albums/o420/ZX750E2/Monster/IMG_0364.jpg)

then, refit onto the air cleaner box

Now, where & how do I mount the filter for crankcase breather ?
Got these.

(http://i342.photobucket.com/albums/o420/ZX750E2/Monster/IMG_0369.jpg)

mount the filter here (I may move it in the future, if I come up with better idea ...)

hose runs like this

Then, attach the rectifier to the TPO kit bracket, then mount the bracket to the bike.

Now, your rectifier / regulator is flipped, under side of the bike, also turned 90∘, so the fins run the direction of air flow. In the last pic , r/r is already mounted, but it's too dark, can't be seen. But it's so simple, anybody can finish it.

The R/R relocate kit, fit and finish are excellent, so I don't mind paying $35. ( even though you  can fabricate the mount by yourself for a lot less money, I'd recommend this kit. )
The crankcase breather filter kit, well, the only thing I actually needed was K&N filter, didn't have to buy the kit. So check inside of your air cleaner box before putting an order.

I'm pretty happy with their products and service anyway.

Great write up!  I am getting ready to do this so the timing was perfect  [thumbsup]

This may seem like a stupid question but is there any reason why you can't fit the filter were the original pipe to the breather box stops.

+1 that's so odd having the breather like that.

that's where i put it... no problem with it.

Are hunduc s21folgore one and the same person the reason why I ask is because of the vapor that is possible on the back tyre.

I saw no reason to relocate the filter at all.  It fits directly onto the breather valve.  Sometimes less is best  ;D.

what i meant i put it on the end of the hose coming from the breather. (no extension to the tail of the bike). my filter is close to the flipped regulator now. vapor to the tire: it is a possibility - the longer the hose, the smaller the probability though. also, if you do not overfill with oil and do not pull wheelies everything should be fine even just putting the filter on the breather directly. lots of people did it that way as well.

so the only way to install is with the crankcase breather box out right?  Does anyone make a kit that avoids taking the box out?

the old TTs had it in the tail under the battery, a special breather box. seems the higher the better.

Not trying to hijack but thought I would show what I did in case others want a different option.  Instead of using the TPO kit, I used I scrap piece of aluminum to hold the coil and flipped rectifier.  I bought the K&N and mounted it where the stock hose enters the box.  I simple 1" conduit bracket secures it securely to the forward side panel mount tab.

... slight update ...

Here's the better photo of rectifier on TPO kit mount.

As you can see, I changed the breather hose routing a little bit.

(http://i342.photobucket.com/albums/o420/ZX750E2/Monster/IMG_0399.jpg)

K&N filter has been moved here. Less noticeable with the seat on.

... hey, I  just noticed I forgot to put the screw on the license plate.

I got one of these in-line fuel filter by Mr. Gasket. (available at any auto parts store.)
Take it apart ...

(http://i342.photobucket.com/albums/o420/ZX750E2/Monster/IMG_0392.jpg)

... discard the filter, cut a small piece of scotch-brite and put it in where filter was...

the temporary liquid-vapor separator.

Temporarily mounted here ...

... and the drain hose goes down here, with the rubber plug at the end.

Like I repeatedly  said, the breather set up is temporary. I used clear-body type  filter casing so that I can monitor the amount of accumulation. After awhile, I should be able to figure out  the size of the catch tank. (Or, I may not need the tank at all. ) If you are setting up a track bike, you'd have to have proper catch tank. For a street bike , it is
 " probably " OK not to have catch tank and mount the breather filter wherever you want (directly on top of the breather valve, where breather hose ends, or at the end of tail section )
AS LONG AS
1) your engine is not overfilled
2) you don't do stupid things like pulling multiple wheelies ...

HOWEVER,
IF, for whatever the reason is, engine ever pukes oil out of breather, "filter mounted directly on top of the breather valve" set up can cause serious problem (oil will be dumped right front of the rear tire.)
I may be paranoid, but I prefer "remote mount" breather filter.

It seems as though you added a whole heap of superfluous tubing, but well done none the less!

I bought the TPO Crankcase breather as well (he's right by the way.  Fantastic product and easy to use) and decided to build one out of scraps I had lying around and powder coat it and make it perrrty.  You can see chewed up metal where I had to relocate the coil mount studs as well as where I botched the R/R mounts, but other than that it looks pretty snazzy.  I also relocated the license plate and used lighted mounting bolts to hold it on to the new bracket.  I don't have a pic of it fully wired, but rest assured it's nice and tidy.

So, ... it was 2012 ...

I finally installed the "oil catch tank".
(https://farm5.staticflickr.com/4092/35362563040_bc6f7161f4_c.jpg)
(Bought the tank at Webike Japan's summer sale. Ordered July 1st (Sat.) noon, the stuff came in this morning (July 5th, Wed).)

Now, I can sleep well ( I don't have to worry about the rear tire anymore).

I just have my breather directly to the crank case with 1-2 in of tubing.

 With all that tubing back from 2012, did you add the oil catch because you were doing lots of wheelies and have noticed that the 2-3 ft of hose was not enough to keep the oil from leaking on to the back tire?

I notice that the hose has some "brown" to it from oil and could only figure lots of wheelies

Another one of a million great threads ruined by PB!

Yeah, I will have to "rebuild" a lot of tutorial thread that I did in the past.
(without photos, they are useless. I will move the photos to flickr, then re-post one by one.)

A Labour of love right there!
