Header pipes/bolts

1986 maxim x 750
I plan on take my head pipes off over the winter to do some restoration.
Bikes really clean hardly seen the harsh elements of rain or sat out. Are the header bolts hard to remove. ?Should i worry about them breaking.?
Is there a method to the madness?

 

no their not put on very tight

yes, it will ruin your day

oil your nuts every day for a week, before you even try

 

Maybe ill leave them alone then.

 

No, we are confident that you will be successful. - well it IS you call, your bike and all of that...

Do as Polock said with the oiling (Kroil, PBBlaster, etc).
Then when the day comes get your wrench on and see how they feel.

Sometimes a nudge tighter and then loosening will do the trick. Sometimes a little judiciously applied persuasion will work. IF you feel you need to heat your nuts, keep in mind there is a gas tank above, grab some paraffin and touch it to where the nuts and threads meet, the paraffin will wick in there and your day just got better!

 

oil your nuts every day for a week, before you even try

That's what she said.

 

I got caught "oiling the nuts" the other day. The wife hasn't looked at me the same ever since

 

Matti bait..........hook, line and sinker

 

cause she wanted to

 

PT Barnum said something about me being born every minute.

 

Hope it was in the garage, and not in the front yard........

 

Got the pipes off today. Came off super easy. Didn't even have to oil the nuts..
No time to clean up the front of the motor.

 

Better luck next time.

 

you missed half the fun

 

I'm ok with that. Hahaha

 

You might want to make sure what end goes into the head and the other gets the nut. I think one end has more threads than the other.

 

Numbered them all just incase

 

Oh Matti, i thinks another line has been cast your way

 

matti ain't sayin' nuttin'

 

but where are you headin ?

 

Headin down memory lane.

 

Off course a little, but does anyone know where to buy replacement nuts. I stumped the local ACE store.
TIA

 

Either at your Yamaha dealer (and wait at least two weeks for the order to come in), or start a conversation with chacal and have them in a few days.
If you are not concerned with looks, get stainless nuts and double them up.

 

yamaha dealership same nut still used in 2005 for atv's or www.xj4ever.com len should have them

part number
90179-06500-00


partzilla has them in stock they state on web site


look closely at the nut it is an allen drive in the top of the nuts

 

They tend to say that about everything they sell, and sometimes it's true. That's been my experience anyway.

 

unless his dealer ship has them on the shelf I would go with xj4ever. I know he has them on the shelf

 

Over 300 of them in stock at the present time..............

 

Guess who just snapped another threaded stud... @chacal what's the link to your parts catalogue for the studs and nuts...

OP - oil those threads too. basically what I've said here is oil your nuts and shaft every day for a month and without really trying to set matti up again you need to use penetrating oil - like PB blaster.

As you can tell these feckers are a bit of a PITA but taking them off and on again is a good thing - moving them is good - the longer they sit without being moved the more chance they'll snap on their own just through 30 years of thermocycling.

 

Not gonna say anything.
Too easy.
Yeah, and too busy.
I'm off to oil my shaft and nuts.
