Dunno if you all saw this in my shock install thread. When I changed my tire last week, my rear axle had some mild corrosion and some surface pitting. Cleaned it up, greased it, and put it back. Yesterday, I dropped out the OEM shock and installed the Penske. The top shock bolt was fine, the bottom shock bolt was fine, but the dogbones bolts looked like this:

The corrosion was quite extensive as you can see. The pitting in the bolt was VERY deep in many places.

Next time you have your 2006 (or any other FJR year) rearend apart, while up on the center stand not only should you lube and check the axle and splines, but drop your dogbones and see if they aren't majorly pitted. I was shocked that my 9 month old (since manufacture) AE was THIS BAD! :angry2:

It's not just the '06's for that particular bolt. Most of the FJR's for all years show that corrosion. I had mine out at 10K or 9 months and was very similar. Fortunately, cleaning it off and dabbing the bolt with some good grease like Mobil Synthetic (red) stops it. Now at 2+ years and 45K+ it's happy as a clam.

You found any other big bolts....or just this one?

And an admin note, if you're going to start this new thread and reference an old one....you are encouraged to include a link. I did it for you this time.

I just finished reinstalling the back end on my 06. I pulled it apart because I suspected this is what I would find, and it was. I found quit a bit of corrosion on several bolts. The two worst were the side stand bolts. Heavy rust. Then the dogbones you mentioned. I lubed and cleaned every bolt, bore, bearing, and bushing.

I also went a step further and unplugged every electrical connector I could get at and coated the pins and sockets with ACF 50 which is an anticorrosive compound. I was quite suprised to see Yamaha had already put an anticorrosive oil on the 3 AC wires where they plug into the rectifier/regulator. None on the DC wires though.

For folks that plan on keeping their bikes for just 2 or 3 years I wouldn't worry much but if your in it for much longer you need to get this done. It's a "pay me now or pay me later" thing.

(edit)

And don't forget to remove the fuel tank cap assy. as the tank is starting to corrode underneath. It needs a coat of grease under there.

Don't start thinking "why is this bike rusting all over." This is typical of every bike I ever worked on. It's just if you want to keep it perfect, these are good things to do.

That is normal for a Japanese motorcycle. Well normal from my experiences anyway. In my past life (read younger) I was a dirt bike racer and the first step in buying a new motorcycle was to take it apart and grease the axles, rear linkage and steering stem bearings. Then you were ready to ride. My wife has never understood this step in 20+ years of marrage, (new motorcycle apart in the garage) But, I have learned the hard way that if you don't do it the bolts will seize. I also have allready taken this step with my 2006 Fjr when I got it. Little more involved than my dirt bikes but worth it! By-the way I just realized I've never said Hey, to the Forum. So I say it now, HEY! I bought a Fjr in July for a trip to the Gap and love it. this has been an awesome site for info on the bike and I am lurking every day.

Never heard of this before on the FJR forums! Any pics ? Guess I'll put it on the list of items to check.

I read of this on this forum a long time ago. I checked mine, and under the fuel cap ring assembly you can see the paint doesn't extend all the way to the opening in the tank. Moisture gets under the ring and creates corrosion on what's not painted. I put a coat of grease under there. Very quick and simple to do.

I saw this a while back and just forgot about it. Thanks for the reminder. Need to get that done. I've had the bottom suspension apart twice on my 04. I coated the thru bolts with the Yamaha Marine grease. Seems to work good as a anti corrosive/moisture. Oh, by the way, welcome to the board woodsrider.

How true. I'm also an avid dirt rider and my wife and daughter just can't understand why my new bikes get taken apart before the first ride. They're grown accustomed to seeing dirtbikes in pieces but were daunted / scared / perplexed when they saw a new '00 BMW K1200LT apart a few years back. So the sight of the FJR in pieces over the summer was no big deal............!

 
Can anyone take pictures of where these bolts are located? I love pictures....they're worth a 1000 words.

Thanks.

Iris, the bolts I was referring to are under the bike, between the wheels. :rolleyes: A couple posts have eluded to the fact that ANY of the bolts, particularly the bolts down low getting splooged, are likely to corrode.

Here's where I was talking about:

The bolt in my first post picture at the top of the page is actually NOT pointed to in the pic above, but it is at the bottom rear position on the dogbones. That is the bolt you can see over the "MVP" letters from my floor jack. Good idea to take all the bolts out and check for corrosion especially around the bottom of the bike.

I just checked under the fuel tank cap assy on my 06 and, yep, there's rust under there along with flaking paint. Added some grease. Hopefully that slows it all down. Good idea to take 1 minute to pull it off and look for rust.

 
I recently replaced the Auminum skyway sliders with Delrin. The bolt on the right side had alot of surface corrsion. I think a contributing factor was washing the bike and then puting it on the side stand. Water puddled inside the slider and then ran down the bolt. There may have been a little galvanic action going on between the bolt and the alum slider. I coated the bolt with rustoleum and stuck it back together.
