Title: header nuts
Post by: scooter on April 15, 2012, 05:54:46 PM
did a search on this and found some have found them loose as soon as 3000 miles. is this something i should be worried about? do they ever come off? i would think that it would be covered under warranty.or is it as simple as just checking them every so often,they look like a pain to get too some say you can get to them from the bottom of the bike without taking the plastic off , this seems impossible to me.i looked at mine and there alot of stuff in the way. any body come up with any neat tricks to make this a easier thing to check. my bike is new and i want to take care of it.thanks

Install Fuji lock nuts In place of the OEM and problem solved...

Don't be! Go on your trip and enjoy it. Nuts will be loose but not falling out.

You should take the man's advice. It's offered in good spirit. Why ask If you don't want to know?

Oh, and and loose is like.. loose and falling by the roadside where a pain becomes a PAIN. ;)

Doubt they will do that under warranty, I wish you the best of luck however. Taking the plastic off is not hard at all, do it yourself and get to know your bike. Replaced all of mine a while ago, fuji-lock nuts are still tight and haven't loosened a bit. And locking nuts are not all the same, go with the fuji-lock style and be done with it. Although I think you are worrying too much about it already, take it into the dealer or check/replace them yourself. 8)

You can reach all of these without removing anythign from the bike.  Its not easy, but its possible. I did mine tonight. I used two 6 inch extensions,  a 1/4 t handle, and most importantly a 1/4 wobbly extension added to my 12mm socket.

did you come in from the side or from the bottom? i have plenty of tools so thats not a problem

To the OP, yes they get loose and some have had them fall off.  I had to take plastic off and loosen the rad to get to all of mine.  Different strokes for different people I guess.

are you guys torquing them or just running them in tight

It would be a thousand times easier to remove the plastic, but I was stuck at home with nothing better to do.  The best idea would be to tighten them along with other work.  It did not take THAT long, and I hate dealing with radiators and coolant.

I went through the triangular cut-out on each side of the lower fairing.  For the center nuts it was necessary to assemble the tool with half of it inside the bike and half outside.  1/4" drive stuff was a must have as 3/8" will probably be too large to fit anywhere.  I did nto even attempt to torque them as the angles were too crazy to get an accurate value. Several were finger tight, though, so I'm sure I helped them.

Heres what I built up to get to them:

I never touched my radiator, Jim must have had a bit too much scotch while doing that? :o I took the plastic of both sides, and had no issues getting to the header bolts. I never used a torque wrench, not sure how you could anyways? The fuji-lock nuts were snugged down real good, would guess around 8/10 ftlbs with the hand torqueometer. ;)

cool thanks guys. is this a one time deal or do you have to check them every so many miles?

Wow you are paranoid!!!!! :o If you install some fuji-lock nuts you are more than likely done, otherwise it wouldn't hurt to check them every so often. Some have tightened them and they stayed tight, others have found them to work loose after many miles "can't give exact amount". I think you should just go ride and not worry about it, otherwise check them after about 3k and be done with it.

Possibly.... ;)   Is there any other way to do maintenance work?  BTW, you know Kiwi Graham?  You guys have something in common although you are a bit more animated.

As Jim said, some have lost their nuts...

You can get to them without the plastic being taken off but you'll find it WAY easier to remove it to get to the two inside nuts. You can get to some of them easy enough, not so others.

During the valve check on my 08, I had the shop look at the header nuts.  They were all loose.  Good to go now. ;D

I see what ya mean.

There's also been some discussion as to whether the nuts are actually loosening up, or if it's just that the copper gaskets seat and break in causing the nuts to need tightening.  I installed a new exhaust system with new gaskets using the Fuji lock nuts and still developed an exhaust leak after a couple hundred miles which required tightening the nuts.  If it's just a matter of the gaskets seating, then it might not be necessary to replace the standard nuts with lock nuts.

Personally, I wouldn't worry about it at 3k miles.  Check them at your 7.5k service.  If you are limber, and don't have huge hands, and have the proper tools, it isn't that hard to tighten them w/o removing stuff.  Nothing against the locknuts, but they do not seem to be necessary.  As mentioned, they don't seem to be repeatedly coming loose.

Never had a problem with them coming loose. BUT, I'm ready for the 15000 miles service so I ordered the fuji nuts and will replace the stock ones at that time.

At 7500 miles, mine were very loose on the 08.   Not dangerously so, btu I should have checked them sooner.

I don't understand this thread...
 
Head or nuts??  :o
 
Is it where you want to take the hit??  :-\

ZG, I'll go with the head. If hit hard enough, I wont remember. The nuts a person can never forget.

Jay, I think that you've been hit on the head enough aleady, you better just run.

I checked the outermost left hand side exhaust header nut (had that side off for an air filter check).  It was tight so I think the others are ok...  Living on the edge, I guess.  I may check the right side outermost nut in a few days but I'm sure that's tight as well.

I just checked. Mine are still there.
