well u kno the pipe thing it is plasticy rubber thats near the carb on the side of a 400ex well it goes to a white little box see through and it is cut in half but no oil or anything is leakin soo is it bad or not thanks.

That little tank is the breather tank for your crankcase(gear box). If it is cracked you will be drawing unfiltered air into your carb(extreme lean)not to mention a whole bunch of nasties into it.Replace it dont plug it off

just put some tape around it or something to seal it, or replace it.

[AtvRider21]

the case isnt cracked its the tube/rubber thing goin to it.

[jb400exxx]

does it connect the airbox to the carb, or is it the tube from the engine to the white breather box?

[AtvRider21]

its from the engine to the white breather box.

[jb400exxx]

then you gotta replace it, or fix it with tape or something if you can. I'd just replace it.

[AtvRider21]

i guess ill just tape it with duck tape .. thanks peace

[jb400exxx]

i don't recomend using duct tape all over your quad but if it fixes the problem and doesn't look to bad then do it. if it's a cheap part just replace it.

[jb400exxx]

if it's part #13 in this pic it's only $5 from servicehonda.com or $7 from a dealer.

[AtvRider21]

wats the part called so i can replace it thanks for ure help guys

[jb400exxx]

i'm not sure, but maybe the vent tube or something, if the parts guys at your dealer are smart they'll know what your talking about. just describe it to them. if you can print the pic i just put up, then just print it and show it to them.

if you buy a new one get it from your dealer, it may be $2 more but service honda charges $7 minimum for shipping.:confused:

[Live2Ride300]

Go to service honda and get the part number then just tell them the part number at the dealer.

if its cracked put a very thin layer of rubber cement on the crack and when it drys put a thicker layer over it just so the cement doesent seep into it
