Staying Cool In Summer Heat

[blankenship]

Hey i check this forum everyday and read all the articals taking in alot of info...............but never heard what u guys think the very best way is to cool a 1999-04 400ex i love my bike but on those long rides i can feel the power loss from the heat want to get the VERY BEST cooling system availible to me

[Wheelie]

Check out www.spal-usa.com. For the price, they are tough to beat. Very effective, not to mention cooling on demand.

have any pix of it installed??

I switched to 20w-50 oil and I deffinately noticed a difference. My motor wouldnt get as hot and it would cool down much faster than 10w-40, also synthetic oil cools a lot too. Run a 20w-50 synthetic and I think you tackled your heat problem. Still a fan, air scoops, bigger oil cooler, different oil cooler any of those help too.

I would be careful telling people to use synthetic oils. Honda does make an synthetic without moly though, for like $9 a quart. Just any old synthetic is way bad though! Talk about burning up a clutch in a matter of weeks!

as long as it doesnt have molydeblum or whatever or a energy saving label your normally good to go.

what about dual oil coolers has anyone heard of that i though of just running inline oil coolers just buyin a second oem oil cooler and fab it in place mayb a bigger oil resivour (sorry cant spell)???.....what u guys think


p.s thanks for the 20w-50 idea ill def try that im about due for an oil change

not true at all you don't know what your talking about and are brain washed by dealers. I have used 4 different kinds of auto synthetic and have had no issues. Oil with a atv picture sticker on the side is the worse oil you can get its junk.

AMSOIL thats all i can say thats what ill be using!

i have an extra oil cooler and you can feel the difference in the heat off the motor and also from one cooler to the other there is a big difference. the oversized oil tanks are overpriced and arent that effective in my opinion.

moly makes ur clutch slip...u need the honda hp4 without moly...or another synthetic without moly additives

[Speedy 400ex]

ok thanks looks like i got to change it again.

I use mobil 1 racing synthetic. Is for transmission, clutch and engine. Is like 10.00 a quart
I also run 112 octane in my 400ex, but I have a 440 kit, and with the 12-1 comp ratio, 112 is what I run.

[Motofool250r]

12:1 does not require 112 it wont do it any harm

but i run 15:1 and use 110

[blankenship]

well thanks for all the tips but i think im going to go with the dual inline oil coolers......does anyone have any picstures of one already done or really good pics of a cbr oil cooler mod i know there was a thread by red_rider once about this but cant find it??

[BigBore24]

not the best pic but heres where i mounted mine. this is just a cheap universal cooler i picked up at a parts store and it has worked well but i would recommend one with a little tougher construction.

i have seen transmission coolers at advance auto that are a little bigger than that 1. could I use that?

[BigBore24]

yeah thats basically what mine is...only its from napa:D

[blankenship]

thats a great mod are u running it inline with the oem cooler or just the aftermarket one would it be too much to ask for more pics mayb of how u ran the lines im wanna poke and stroke my 400 (bore to 426 11.1 comp with 4mm stroker crank) and need to get it cooler too any help would be great

[CoolCat]

I know I don't need to run 112, I could run 110. But it isn't good to run 87, 92, or 93 octane. I need 110 or 112 for my motor, it runs cooler.

[BigBore24]

i ran it inline with the oem cooler. i just cut the oem steel lines where they are straight and used oil resistant hose to connect my cooler to oem one. i have had it on there for about a year now and have had no problems with it. it was hard to get a good pic but heres the best i could do

[BigBore24]

another

[honda729]

nice mod, i think you can squeeze another stocker in there if you like overkill, lol
