Quote from: STLanduyt on January 13, 2026, 08:53:07 PMAs I was cleaning the left swing arm of the FJ1100 today, I noticed that large pieces of rubber were falling on the ground near the engine side of the chain.  My chain seal guard is falling to pieces.  New seal guards are not available AFAIK.  There was a General Discussion topic in 2017 titled "Seal, guard, chain slider.... 1984-1987" that contains a photo of the seal, guard.

A seal guard is still available for the FJ1200, but it has a different attachment than is used on the FJ1100.

What solution have FJ1100 riders found?



I've gotten many things from ebay, you just have to be good with searching, you can also search craigslist or FB Marketplace for "FJ1100" and see what comes up, there are often some people parting bikes out across the usa, you may be able to have them mail you parts. You could def find a full swingarm for the 1100 on ebay with the rubber piece, just would have to spend more $ but that comes with the territory of keeping a vintage bike running.

The glass is not half full, it was engineered with a 2X safety factor.

I bought the seal guard from Hot Foot Moto.
Thanks Pat, Randy, 86FJNJ, and FJmonkey!

The FJ is still being cleaned after sitting idle for too many years.  The carbs are with Randy at RPM, meanwhile I am in the process of disassembling, cleaning, restoring and/or rebuilding, and lubricating the various components, which brings me to the major reason for this post ... what is the best way to remove the rear shock and disassemble the swing arm to clean and re-lube them?

I have the Yamaha Service Manual, which has been my guide, but I thought it best to ask the group before I plunge ahead.  I am working in my garage, with the FJ on its center stand.  Unfortunately I do not have a motorcycle mechanic's lift.  While this is not an ideal set up, is it a sufficient work space for this project? 

BTW, the first successful repair I made was to the helmet/seat lock.  The helmet lock no longer locked.  Turns out the locking mechanism was missing its spring, which I replaced with a spring from an old ball point.  Works like a charm!

1) Remove lower cowl,  seat and side panels (tank optional) 
2) Remove rear tire assembly and caliper. Don't disconnect brake line, just tie caliper up out of the way.
3) Disconnect swing arm linkage
4) Loosen, push through and remove swing arm pivot thru bolt. Don't worry, the swing arm will not fall out.
5) Remove swing arm. Note: the swing arm will not pull straight back, you have to lift up the arm at the front pivot shaft before you pull out. I do this by twisting the legs of the swing arm to get each side of the pivot shaft to lift up. Once the shaft is lifted up you should be able pull the arm back and out.
6) Remove the shock adjuster chain and top thru bolt on the shock. The shock will drop down. Be careful, try and not let the shock drop to the floor.

Cheers. Pat

If the chin fairing and exhaust are off you can put 4"x4" wood blocks under the frame rails. It was sturdy but I added straps to my ceiling joists as an extra safety.

I also recently got this scissor lift and it works great. Just make sure it's on the frame rails and not the engine oil pan or drain plug. It works on my FJ and my Honda.

Not safe long term but I briefly hoisted my bike with straps on a ladder to lift the front end enough for a quick front end change.

Pat and Eric,

Thanks for the guidance!  You gave me confidence that I was on the right track and directions on how to proceed.  Eric's garage set up is similar to mine (excluding the Countach poster) and I will use a couple of his ideas to elevate the FJ.

My best to you both, Steve

BTW I hope someone benefits from my tip on using the ballpoint pen spring in the helmet hanger lock! LOL

I did use the center stand on the FJ when it was on the wood blocks it helped keep it stable. If your front wheel is still touching ground or if not you can put blocks over that too for stability.
