Dual oil coolers and whitebrothers eseries exhaust on my 350x

[NOS_350X]

Well here are the pics boys.

[toyota200x]

It is good to see some high quality exhausts on trikes. I think you need to invest in some seats. Good looking trikes!

[kilabeez0]

overkill??

[BIGCRIP28]

nice....... :D

I didnt know that an E-series was availible for a 350X? Looks like a 400EX header pipe, I can see the slight benifit of the 2 coller system, just be sure to run MORE oil in the engine because filling up 2 coolers instead of one while riding is going make you a little low. Looks good though, I wonder how much it is going to drop the overall temp? If its a noticiable differance I might look into doing the same thing, I have an extra cooler laying in the shop.

I added 3/4 of a court to it. It runs MUCH cooler to me its a night and day diffrence. Its a win win situation, larger oil capacaty (sp?) and cooler engine.

The whitebros isnt made for the 350x, its a 400ex and i fit the headpipe onto the 350x. Now i can run any 400ex slipon.

What did ya have to do to get that 400EX header to work? Did you bend it, and if so, how did you bend it without damaging it? I tried this awhile back but temporarily gave up. Was going to mate the 400EX stainless header to the stock 450R silencer. Got a close up pic of the junction between header and silencer? Looks like a sweet mod!

I cut, grinded, and welded. Only to the headder. I think if you want to do the stupid 450 modd use a stock 350 exhaust. If you want ill sell you mine.

Ok next question, How did you ajoin the 2 oil coolers together and where?

[NOS_350X]

If you give me ** email addy ill just take a bunch of detailed pics of it, because i'm shure no one elce here wants to see that.

[The Goat]

anyone else done this. I'm interested in it if it works

[350xrider911]

i want to know about the dual oil cooler set up im doing a 460 stroker set up know and want it to run cooler i have an hmf slip on mine pulls hardder than a 440ex do i see a 400ex carb on the white one.

[tanks350x]

here's a question for ya.... Is the oil pump strong enough to pump all that oil??:wondering I'm wondering if the extra cooler puts more of a strain on the pump, with the extra volume

[willrideanythin]

FST makes an aux oil cooler kit. I think its under 100

[SWIGIN]

i know my 350rx is the coolest 350x motor i have ever bin around... im useing a 450r cooler.

built 350x motors need more cooling IMHO.

with a new pump its fine, one thats only working 50%....not so good

[AJZ_200X]

Do you have a sound clip of that exhaust. Looks wicked (probably sounds wicked to)

who what when where how?

I want one.

[NOS_350X]

do i see a 400ex carb on the white one.


At that point in time it was acutaly a 05 trx450 carb. Then i went to the 400ex carb, Then to the FCR.

I have never had any problems with oil or heating on that bike. Mainly jetting and octane rating is the biggest factor on operating temp You richen it up and it will cool your bike down if your having problems. I woudnt do the oilcooler unless your running frequently in +100 degree temps.

Ill see what i can do to get a clip of that exhaust. I also did a new one that sounds even better, Its a DR D off of a trx450 Im going to do a writeup on how to do the exhaust and get it on 3wheeler.org/vb

[The Goat]

down here during the summer it sits over 100 degrees...I figure every little bit helps.

NOS...what was your jetting with that fcr...I know mine won't be the same, I'm just curious about a starting point for the leak jet and main.

also...what in god's name does that "mikuni" style jet in there do...and di you change it?

[Blown 331]

So what exactly had to be done to the head pipe? I still have brand new take off 400EX exhaust from a 400 I bought new in 2003 and I would like something other than DG on my 350X.

[BigGreenMachine]

White Brothers E2 is the way I would go. Its a great woods pipe.

a stock cooler is not big enough for a big bore stroker 460...its needed

[NOS_350X]

Swigin, What tep do you run at that you must have a secondary oilcooler? now is this fact that you go big you must get one or is it just your oppinion?

Goat, With the 400ex carb and 450 carb i was well into the 200's (around 220 on the ex carb) With the FCR carb i then was able to be around the 175 range.

Im not shure exactly which jet your talking about (its been a while since i had to pull the bowl off) but its eather a Leak jet for the acclerator pump, or a starter jet. no need to change.

Blown, 1 easy cut, Grind, Weld and your set, With the 400ex headpipe and a 450 stock or aftermarket pipe the rear mount even lines up, With the 400ex rear pipe you have to make a new location for the rear pipe mount.



Isnt the Eseries pipe the one that was falling appart on everyone?? i think so.

[The Goat]

with the 37 fcr...were you able to use the choke...or...did you simply jet it to where it would start?

...stock in the 37 I purchased was the 42...seems like a 45-48 would be more correct.

But back to the thread, if you still have pics, would you post them up? I'd like to see this cooler mod.

also, with your huge main jets, were you running something larger than an 83mm piston?

[SWIGIN]

temps range from sub 0 to 100

and im talking about larger then stock coolers not dual stock ones.

i used to run a stock cooler on my 350x quads but a 450r cooler cools much better. and the 460cc motor my buddy built will over heat when it's 80 degrees and up with a stock cooler.
