85 maxim 700 breather like hoses comming of carbs

when I bought my bike off this guy he had 4 hose coming of the carbs(1 for each carb).then he had them going to a air filter. I will put up pictures tomorrow if you need them. I looked at another bikes online and did not see them on. I was wondering what are the point that is their. I would like to take the hoses off because they look terrible. It is also hard to fit my pod filters on.

 

I assuming that you mean the rubber neck that connect each carb with the airbox, right?...If not I will need the pics...

 

The hoses that come off the carb are overflow drains. I would NOT recommend taking them off. Besides, when the carbs are in place, to boots are installed, and the airbox in its correct position, those tubes are just about invisible. They are black, and hidden in the shadows.

But Dave . . . He said the "P" word - he has no air box.

 

Zip-tie them to the side of each pod. Inboard of the pod in order to "hide" them better.

So over flow gas would go thru them tubes and thru the air filter. I bought the pods before I read all the bad stuff about them but just gonna give them a try. I did not see them on other pics of the same model maybe I they had them hidden like you said. I just don't understand that the gas would go thru the air filter.

 

No, it doesn't... They just droop over so if the bike tips over, the gas would drain somewhere else instead of on to a hot engine. They don't go into the airbox. The only hose that goes into the airbox is the one from the crankcase breather

 

Oh their is another small air filter that the overflow goes too. Not the crank case vent. the guy I bought it off of must have put it on their. All of the overflow hoses come together into a seperate air filter. I wonder if I could take that filter off and run everything down

 

Can you show me a pic? I'll "SC" you with my cell #

That's the most ridiculous thing I've ever seen.

 

Yeah and he had hoses sticking in other hoses to make it longer

 

Do you think I should remove the all together or just route them all down past the motor and get rid of filter

 

I'll try to get a pic of mine tomorrow afternoon if I can get through the snow

 

Bet that mousetrap made synching the carbs a real joy...............

 

Wow, just when you think you've seen it all. Hog will get you a good pic. I can't cause he has my carbs

 

Your carbs aren't for this bike anyway----
Btw, here's how your carbs look now

 

You know ... A fleeting thought: those hoses almost look like someone was trying to create a version of the Xj1100 "octopus". Maybe they had the wrong info, and actually were trying to 'figure it out'.

 

Hog, you're way too organized. How do you expect to lose any parts when you put them in neat little trays? Where are the peanut cans and baby food jars?

 

Here is a better picture

 

Haven't been able to get to mine yet, but here's all you need......

The hose between carb 1 & 2 is an overflow tube. its simply an empty tube about a foot and a half long or so. same for the hose between carb 3 & 4. They just exit the back of the rack, and droop down behind everything. it the bowls get too full, or the bike tips, the fuel just runs through the hoses to the ground. the hose that is between carb #2 & 3 and connects to the metal T is your incoming fuel line . get rid of the rest of that gobbledygook. it doesn't have any place or function there.

Dave

 

OK so take all the hoses off except the fuel line and leave it or should i get hoses and run them down. It really dont matter to me unless having no overflow tube is a huge safety factor.

 

I'd put overflow hoses on. I guess you could cap the connectors, but it's a safety thing and I'd as soon leave them there. Whether you go with the airbox or with pods, the hoses are just going to be two black lines between the carb boots or the pods. Once everything is installed you'll hardly see them.

Funny, I just saw a set of XS11 carbs that look right like what hohenstein showed---- i really am wondering now if he has an incorrect rack!

 

Jeez, Dave! Do you have a real job, or is cleaning carbs just what you do? Almost every thread has somebody liking you for shiny carbs! Are you able to do them blindfolded yet? You and Len are fast becoming heroes to me!

 

85 XJ700 Airheads have breather port hoses coming off the top of each carb.

The PO took those breather hoses, and connected them all to a filter. Disconnect all that poop, but LEAVE the hoses off the breather ports... they should be about 12 inches long off of each carb.

 

Read chacal's post in this thread...

how could i check if i have the right rack

 

Any series of numbers still visible on the bottom of the bowls?

 

Hitachi 33's with vac ports.... check your jet sizes. that should confirm if you have the right rack or not...

 

The number on the outside of the bowl was c-2 and the main jet was it looked like 107

 

Do you guys know what the numbers should be or could I research and find it somewhere.

 

you can find jet info here...

hohenstein, not the little cast number in the oval on the edge of the bowl....I said on the bottom of the bowl--I mean on the BOTTOM of the bowl. There were a series of number printed on the bottom of the bowl. If none are, look on the sides of the bowls, or on the side of the carb bodies themselves.

 

I believe the hitachi's are printed on the bottoms and the mikunis are printed on the sides......I Think you have mikunis

 

Look at the pics he posted earlier. They are definitely Hitachi carbs.

I have seen these oddballs before. I have owned these oddballs before, some of the 85 airheads have them. (I think lower numbers, but i cant confirm)... As long as the jet sizes are good, he should be fine...

@chacal, you got anything here?

 

Yeah I checked and I have the correct jet size

 

You got the right carbs. Po got creative.... See my earlier post with a link.... There is good advice there

 

ok bringing this thread back i am having trouble and want to make sure this is not the problem. As of now i don't have any hoses coming off of the Breather ports up top. i am not sure if i should plug them or run a 12 in hose of them. would the ports cause a high idle because like a vaccum leak.

 

On my 85 xj700n all 4 are long enough to route down and behind the engine and simply vent into the atmosphere. On mine there are actually a couple of clamps that they fit into. I would replace them all with hoses long enough to vent to the bottom and zip tie them if there are no clamps.

 

Yeah they're pretty long...about 12 inches, maybe? I don't think it will make any difference how it runs if you have or don't have them. As was already said up there^^^ they're overflow hoses and usually do nothing. I think if you leave the choke on too long, you might get drips coming out of them. Or if your bike falls over...
