Well went to grease rear linkages, upon removal of pipes etc ( was going to really strip and clean) found the chain has eaten almost to bolt where the linkage bolts to the swingarm!! Taking it off to see if can be repaired. Guess in hindsight I should have replaced the swingarm/chain guide protector thingy from when it disappeared under the back tyre 4 yrs ago! Oh well. They do say that hard work pays in the end but laziness pays straight away.

Any pictures? Inquiring minds need to know ...
"laziness pays straight away" That's a GEM!!!
Thanks!
Good reminder on why the guard is there and can what can happen. And your saying is a gem.
Every time I look at removing something or modifying a part the first question I ask is "why did the manufacture do it this way or install this part". They rarely "gold plate" things and most often have a good solid reason why they did it that way.
Not related to the post but something to think about.
An engineer once told me when you make a part stronger you just change the failer point to another area. :wacko3: :lol:

All I can add is :mad: SWINGARM!!!!! Bloody hard to get out!!!! No pics yet have to get it out and then we will see. Bloody grrrrrrrr!!!!
:empathy3: one of the swingarm covers on ebay last week ,
Nope. Got it out. Might have had to remove rear subframe,wiring,air box and battery box but its out. Weld her up tomorrow and get chain guide but I WON!!! Thank the gods what a wrestle!!

I'm with George here...
During my FJ rebuild, I found the chain guide to be somewhat worn... I figured it's there for some reason...and clearly, it's taking some wear as a sacrificial part. Swapped it with a fresh one.
On the engineering point of just moving the failure to some other area... When we build rock crawlers, bigger tires mean you start to break Birfields...Step up to hardened Longfields and you start to break axles...up the spline count on the axles and you start to break u-joints...upgrade to Tom Woods drive shafts and you start to break ring and pinion gears...swap to biggger third members and you break the transfer case mounts...Through-bolt the t-case arms and you crack the mount welds off the frame. I'm about to double-gusset the frame tabs and I'm told the next failure point is cracking the transfer case in half ($$$). Should have just kept it all stock! :rofl2: :rofl2:

G'day. Noticing on parts list that the chain guide is listed as not available??? Sending Missus to bike shop tomorrow with part number. Hoping they can get it. Tho last time toowoomba Yamaha shop dealt with her they pulled a swiftly and sold her 2 sets ( yes 2!!! ) of rear brake pads. When I asked last time about the availability of parts for fj I got laughed at and told "good luck". One hopes they are helpful . Other side of the coin Independant motorcycle wreckers AreGREAT!!!! Said they had a rear tyre for me,miscommunication, fitted a second hand tyre with a good amount of tread NO CHARGE and still ordered a new tyre for me and is looking for fj bits for me. Toowoomba Yamaha are rip off and slack arse locals be warned. Taking advantage of a pregnant tired woman who doesn't know about bikes. Pr***s!!!
Rant over

NJona86FJ,
G'day! Never quit, never surrender! :biggrin:
Get the correct Part Number. Crank up Google.com and put in the word Yamaha followed by the Part Number, in quotation marks. If nothing good appears, try the same trick on Ask.com and Dogpile.com too. Dogpile is a search engine that searches many of the search engines. You will see a lot of duplicate results, but zero-in on the results that you did not see, with the other searches. Now certainly, websites can make promises that inventories may not deliver, so a follow-up phone call is a good idea. If 18 places say No, and just one place says Yes, then you WIN!
This site research can help you win, with the wrecker yards:

Happy hunting!

Neil, Is this what you are looking for??

I'm in need of the same swing arm guard. Mine had a little damage on the top of the pivot. Cleaned it up with a sanding disc , removed maybe .030" max. The PO built a chain rubbing block with some nylon and aluminum bar stock. I will post up a picture when I get home. It's quite a thing of beauty...

Here you go: 89-93 Swing Arm Guide (http://www.rpmracingca.com/proddetail.asp?prod=M%2FC%3ASAG)
Randy - RPM
I thought I had already looked for that part on your website :crazy:
I guess that's what I get for thinking.
Joe
Cheers fella's.
Got my swingarm back today all built up nicely, Randy if the locals can't get one for me your the bloke for the job. Also eyed off your choke assembly, will keep you posted.
Cheers
Neil
G'day Neil, The seal guards for later models are still available from Yamaha, as I got one for my 93 about 18 months ago.
The guards for earlier models like your 87 are apparently no longer available. Not sure what the difference between early and late models would be, but you might be able to modify one to fit.
Tony.
Try this one neil,, 161090949905 ebay , rubber chain guide :scratch_one-s_head:
Wow. Swingarm shaft is mediumly Brinelled, cleaned it and all bearings greased, all back together and ok, will have to grab a chain guide off you Randy at some point, not immediately tho, FINALLY took the krauser rack off and put original blinkers on ( no more fat arse). It will be coming apart again, eventually, to fit guide, new bearings and seals,shafts etc.
cheers
Neil
