Title: Advice needed for relocating rectifier/ crankcase breather mod
Post by: Fruity on April 25, 2010, 10:16:03 PM
hi fellas,

i live in malaysia and it gets really hot here and on top of that my bike is an 04 monster s4r which gets really hot when stuck in traffic. yep, you guessed right, i pretty much ride around with almost cooked family jewels when i do ride into town. so i have done some search on the forum and net about how to relocate the rectifier and come up with 2 questions.

i) seems like the most common place one would relocate is underneath the seat where the suspension link is. unfortunately my bike has high exhaust and one of the connector pipes run thru there. would it be suitable?
ii) that spot is right above the tire and very exposed to the rain and muck. would that be a problem?
iii) i have also heard of using aluminium as heat sink. how big a piece and thickness would be suitable?

thanks very much for all the help.

cheers.

I used the TPO parts mount on my S2R, and I live in tropical northern Australia, Lots of Rain, heat and Humidity
It used to get wet all the time and never had a problem.
The Regulators are normally sealed up pretty tight.

thanks howie, was wondering if you have done it yourself. i can't justify buying from TPO and paying a huge amount for shipping to malaysia. i've seen some self mods and would like to try a DIY. just wondering what kind of thickness on the Al plate to use.

cheers.

anything thick enough so that it wont bend or defelct onto itself is fine.

for aluminum id go for 1/8th inch. it can take a nice hit by a rock and not dent. plus aluminum is a pretty decent heatsink. throw some CPU gel in there and u got ur self a nice fat make the beast with two backsing piece of heat sink.

this is pretty much how mine looks like. just straighten it up, and drill that other hole.

I have an older Monster, so mine is up front in the air stream from the factory.  Have fun fabbing.  Like He Man said, you can't go wrong with 1/8" thick.

all i did was just flip the rectifier so that it sat underneath the fender. had to drill a couple of holes through the plastic, but that was it. I painted it black so it could blend in tot he fender. if you have your rear tire hugger, you shouldn't have any issues with rocks and stuff flying up on it.

generally S*Rs dont have rear fenders. dont know why, cause that shock gets dirty as balls cause of that.

now that i have looked closer it seems that most of you have got your oil breather reservoir (the big black thing which the rectifier sits on in the original position) out. now this is going to veer off the original discussion. is that advisable??? cause that really hinders with modding the location of the rectifier. i'm sure it's there for a reason i'll have to work around it.

From technical/mechanical standpoint, most will say...No.

But Many do it regardless for aesthetic/personal preference with no problems...and a very Few with problems.

YMMV.

Post by: Fruity on April 29, 2010, 05:39:53 PM
did some search on that issue. some say, in fact these guys are expert of the business, that by removing the reservoir it'll spill engine oil on the rear tire and that means  [bang]

It is possible to mount the filter higher to prevent spills/spray...

That said, I haven't had any issues.

is yours mounted up high? i really liked the way Cellis (featured bike of the moment on the homepage) mod his breather on his s2r1000. he had the K&N filter directly mounted on the breather. wonder if he had problems.

Directly on the breather also:

cool !!! is that a K&N filter sold by TPO and a nichols breather? what do you ride? would a 2V or 4V make same pressure in the crankcase? meaning would a 4V spill more oil?

thanks darkstar you've been great help.

the nichols breather is one of the better ones. looks like there's some seepage on the filter from your picture. it doesn't get more than that does it?

The crap on top is glue.  That filter has been on there for about 4 years with about 10k mi. with no cleanings.

I've been shamelessly copying everything Dez does, at least in the suspension department.

Here's my new rectifier/coil mounting plate on my 695, freeing up space for the gas reservoir on a 749 shock (not yet fitted).

(https://farm4.static.flickr.com/3313/4580295111_9174aa0371.jpg)

And here's a photo of the TPO K&N crankcase breather.  I painted the top of mine satin black.

(https://farm5.static.flickr.com/4020/4580295117_686622124b.jpg)

Next step, cut the metal tab that the coil used to mount to off, then respring my 749 shock and fit it.

this... is awesome.  I have been looking for a good way to install and hide my PCIII.  Most people stick it on top of their battery, but I think I've got some gas tank expansion issues because I simply cannot get mine to fit under there.  But this looks very nice.  I think I can justify snatching up the TPO regulator relocator kit now  [thumbsup]

just to let you know, theres a difference between the 749 and 749S shock. one is a sachs and the other is a showa.  both fully adjustable, but i dont think the sachs is rebuildable. the 749s is shock is the same as hte 999 shock.

I've actually redone the plate since that last photo, as a test fit of the shock (I'm yet to get it resprung, so it came right back out again) had the gas reservoir just a few millimetres away from the coil HT lead.  There's plenty of length in both coil leads, so I moved it back about another 12mm.  Now there's oodles of clearance.

I could be wrong, but I think gOoIe B is talking about the defect with the Plastic tank and many people have been dealing with this issue as of late.

You could just install the Breather Filter kit and ditch the hoses on the vent tank.  The kit filter connects to the OEM Breather Valve and provides plugs to plug the hole in the air filter box.

You can get an aftermarket breather valve but it is not required unlesss your current one is leaking or you just want the bling.

You can leave the rectifier connected to the vent tank which will serve no other purpose except as a mounting point for the rectifier.  You can also purchase the TPO Rectifier Relocation Kit or make your own to ditch the vent tank which like I said will serve no other purpose once you have installed the breather valve filter kit.

cool... ordered the filter but passed on the bracket.  i think i'll still ditch the breather box, but just drill a couple holes in the plastic tray under the seat, and mount the VR underneath the tray, on the tire side.

I put the k&n on my bike and oil comes out pretty good at highway speeds, around town though its fine. I'm going to try Stuart's idea of the extension tube and see how that works for me.
Title: Re: Advice needed for relocating rectifier/ crankcase breather mod
Post by: scott_araujo on May 18, 2010, 08:26:49 AM
An extesion tube is a good idea.  There were some nice pics on TOB of someone who had nestled it nicely into the crook of the frame with the chrome cap facing out.  Also, don't fill your oil all the way to the top mark when cold, try the lower mark.  Keeping it a little lower helped Infidel with the same problem.

i wonder if the vent tank can be replaced by something else.  That is, maintain the functionality of the breather/tank, but something a little more custom looking.  I've been digging around online for a replacement tank that could bolt to the frame, but not had much luck.  not even with anything that could be lightly modified to work.

any ideas?
Title: Re: Advice needed for relocating rectifier/ crankcase breather mod
Post by: scott_araujo on May 18, 2010, 06:13:32 PM
It's basically a combination baffle and expansion chamber.  You could probably use anything that would prevent oil blown up the pipe from going into the air cleaner.  Maybe cobble together something from a Budweiser shorty can  [laugh]  Or maybe Peroni.  Do they make shorties?

I'd like to do something like this myself to keep the vent going to the air cleaner but still get better cooling to the voltage regulator, maybe move the second coil so I could take off the side panels.  Not really high on the list of projects and things I need to get done though.

i mounted mine earlier today... filter fit nicely.  my only question now is to verify that the regulator doesn't need to actually be grounded or bolted on the frame, right?  i wanted to just flip it on the underside of the lower plastic fender/tray...just drill a couple holes in it and mount it there.  a friend told me though that earlier bikes with single phase needed the actual metal of the regulator to be grounded.  i don't want to burn up the voltage regulator.

The case doesn't need to be grounded - the green wires are ground.  I ran mine disconnected from the bike while I was stuffing about, with no ill effects.

Just saw your post, sorry for being late. if you already installed teh shock, youll notice how light the spring is. So not suitable for the monster. ih ave a 1091-31 (150lbs w/o gear). without revalving, it works pretty decently, smoother then the stock by far. Im not sure how much better it is with a revalving. and honestly, i rather not. Reason? You can get a used ohlins on ebay for about $500. The revalving would be half that price. Not worth it IMHO.
