1985 Yamaha xj700 Maxim Help

Hi, I hope someone out there can help me with a few questions I have about my 1985 Yamaha xj700 Maxim I just purchased.

1) When you start up the bike it idles real high. There are two hoses coming from the carbs just hanging there. Does this sound right? Well actually one of the hoses has a bolt in it. Could anyone tell me what the problem might be and how to fix it?

2) Is there a repair manual for a 1985 Yamaha xj700 Maxim? I've looked and had no luck finding one.

Any help anyone might be able to give me would be greatly appreciated. Thank you
Brian

 

Check this out for the manual.

I do not condone the reproduction of copyrighted material, but sometimes its so convenient.

 

The only book for the XJ 700 is the Yamaha service manual. Nobody else published one for that bike. I'm sure that you can get one from "chacal" our local parts guy. He can be found in Sell, Trade, Swap, Wanted area of the forum. He would also have just about any part that you would need for that bike. A good idea would also be to get a set of the XJCD's there is a ton of information there as well. Look up the XJCD on the forum, they're fairly inexpensive, I think that I paid like $10 for my set. As far as the hoses on the carbs, there should not be a bolt pluging it up, I think that what you are refering to are the drain hoses.

 

If choke is all the way left it will idle high till you move it slowly to the right the idle should lower. I'm thinking the 2 hoses you are talking about if they are coming from the carburetors may be overflow. Not sure without a pic.

 

There should be 4 hoses coming of the carbs and just tucked away, I think they are breathers but I don't know why one would have a bolt in it. Have you tried adjusting the tick over, there's a knurled knob at the centre back of the rack which will adjust the tick over but warm her up first.
Not seen it mentioned recently but the XJ cd is far better than the manual, if you search around on this site you should find how to get hold of one. I have both but much prefer the cd.

Faighaigh.

 

I myself have a 1985 Yamaha xj700 Maxim. How do you reay know if its a Maxim X , an XJ700N or what. I am a new rider and this is my first bike.

 

Simple..... Maxim X is liquid cooled so it has a radiator and fan in front. If there's nothing like that at all, then its an XJ700 (airhead), not an XJ700X.

Welcome aboard!!!!!

Dave Thanks so now i know its an xj700 maxim x, cause it does have a radiator in the front. is there a special spark plug wrench we need to use? the ones i have dont fit at all. I would like to give this bike a good tune up and oil change. Just learning all of this. Just bought the bike yesterday. It may need some carb work from sitting. I drianed the old gas and put some high octain gas with a little octain boost. seem to work it a little. Thanks Dave

 

Often when there is a bolt jammed in one of the hoses, it means something was coming out of that hose enough to bother the person who jammed the bolt in it. In other words, gas was probably overflowing from the overflow lines! I'm pretty sure those carbs have overflows.

That means something bad was happening and someone made it "go away." I had something similar on my bike when I got it. You need to go through the carbs, I would think. You won't get a decent idle until you do.

 

You'll find lots of good info here: http://maxim-x.com/

Including where you can find a sparkplug socket that will fit in that deep, narrow well. I also saw something at partsnmore.com that looks an awful lot like the original plug socket from the toolkit. Part no. 35-0078.

 

Sounds like you have some fun ahead of you with this bike. Put up some pics

 

an 18mm deep well craftsman 6-point 3/8" drive will fit. With an extension of course.
Welcome aboard.

 

I just use the one in the tool kit works great

 

Hey Desinger_mike. Thanks for that info on the 18mm deep well craftman. I am so glad i found this forum. You guys hve been a lot of help in the few things i have asked. But here i go again, and it may be the last question. how do i check my oil level. I just ordered a repair manual on a cd for the XJ700X. I hope this would help. And when i recive it i am will to help other like you guys heled me. Thanks.

 

autosdafe, my bike didnt come with a tool kitt but its cool. as for fun YES i have been having fun since i got it. Cant wait till i get it right.

 

To check the oil on my bike You put it on the bike stand and run the engine for a sec. Then on the bottom of the clutch case is a clear window that will show the oil level. It may not be the same for yours.

 

Just checked some pics and it's the same on yours.

 

Hey everyone. I would like to know what some of you think about seafom. ive been getting mixed stories on it. I would like to know what you all think about it and what have you used it for. Like always thanks for all your help

 

I think seafoam is ok added to gas. I was debating putting it into my crankcase but I have decided against it because I am afraid some will remain in there even after I drain it, which would screw with the oil and I'm scared of reducing my lubrication effectiveness.

But let me just say what others will probably also say--seafoam is not at all even close to doing proper carb work. I think of it as a way to get water out of my gas tank and that kind of thing. It won't fix any problems in the long term.

 

Many say good for maintainance. Add to cranck case before oil change to clean it out.
