Don't forget, dry clutches saves lives....

This has been nagging at me for a few days now.  While these bearings appear to be standard on some bikes I don't understand why you need them and what forces are applied to the swing arm that the inner bearings don't deal with.
The standard thrust washers are thin and soft and barely show a mark which would suggest they don't take any significant load.

Hey Noel, Do FJ's need the YZF750 thrust bearings?
Of course not, but, when cutting down the YZF1000 (Thunder Ace) swing arm, why the hell not include them? When I think of our heavy loaded FJ's in a right hand sweeper, I can envision where the left side thrust bearing would take *some* loads, and the opposite side on a left hand sweeper.
Remember we have heavy bikes, and carry passengers/luggage..and now many of us are running modern tires which grip better.
A well lubed washer under the dust cap would do the same thing as the needle bearings...no biggie.

No need for nagging thoughts on this subject....However, keep a eye on the big picture...I keep telling you... this moditis is some serious shit....

Cheers! Pat

Pat, "Because I could" sounds like a perfectly valid reason to me.

Anybody happen to remember the link for that YouTube clip of the Firestorm with the tambourine "emulating" a dry clutch?

Japanese Ducati - yes, they did it! Is this it ?

 When I removed the swingarm there were no bushings inside the dust seal. If I did not have a parts bike, to dismantle the swingarm from, I would not have even known there were supposed to be bushings in there.  The real issue was of course the length of the collar (race) being so long the bushing could not be installed . With two bushings the swingarm would not fit within the frame. So removing three mm of bushing (race) allowed bushings and removed side to side movement. I made sure that there would be enough surface (of the race or bushing) left for the bearing to ride on. A torrington bearing would obviously help reduce friction under load of a sideways force. But since a motorcycle leans into a corner most of the load is directly on the bearings. Side to side is not that relevant. That is how I see it. Am I wrong?

Rossie's back on a Yamaha again ! Hopefully it won't get to ugly with Lorenz :empathy2:o.

Rossi is sure pumped to be back on a competitive bike again.....He my even sneak a few wins.... but i believe he knows Jorge is the man now and will probably be really happy just having a chance to get podium finishes in the dry.

KOokaloo!

There is a motogp race in Austin TX in april    :scratch_one-s_head:I think. Anybody going? sorry for thread jack BTW. I must say the info on this forum is very helpfu :good2:l and it looks like you put it to good use. It is too bad the previous owner kind of did a hack job though . Good job checking it over smart move .

 To summarize the project to this point. I modified the clutch as per Randy's advice on the clutch files. He delivered all the goods. Thanks Randy. The new cover, pushrod, shift shaft etc. were installed. Safety check done, insurance on. Plates transferred from the FZR. Ready to ride? No the dang clutch slave cylinder started to leak. This is on a Tuesday and no one has one in stock. Most bike stores have nothing in inventory except stuff someone didn't pick up. So Paul Wagar express shipped me a spare and after that was fixed I was ready to go. Oops wait the friggen master cylinder starts to leak. After it was removed and cleaned it works fine.
  Finally I could go for a ride. Well holy crap!! A standard FJ is an awesome bike but after all the mods? I have a mint condition low mileage FZR1000 with only 3000 k's on it so it rides nice, but I will take the FJZ1 any day. What a revelation. When guys spend hours and weeks modding their bikes, I now know why. I just had to use the word KOklaoo. My bike has blue dots.FZ1 master cylinder. Emulators. Wider FZR rim. Corbin seat. Penske shock. FZ1 swingarm, wheel and brake. Supertrapp stainless four into one. All these little things make a world of difference. I am absolutely going to do a complete bike following the mods here that have been tried. I am a convert. I have had 5 FJ1200's with zero mods. This is my first and it rocks.
