Bicycle Repairman Posted March 2 Share Posted March 2 My first Yamaha was a 1980 XS850 Midnight Special the previous owner had installed lower bars and a bullet fairing. I wish I still had that one. The current project is a 1995 FZR1000 EXUP with 162 miles on it. It was "stored" (neglected) for 28 years. During the year it sat (neglected) in my garage, mice had filled it with dog food and damaged some of the wires. Long story short, the last thing before it's like a new bike is fork seals but I don't have 1995 manual/supplement to tell me the factory air space/oil lever for the KYB USD forks. I assume compressed with springs out. Anyone? Thanks, Danny 1 Quote Link to comment Share on other sites More sharing options...
Moderator Snakebite68 Posted March 3 Moderator Share Posted March 3 Trust this at your peril... After a quick 2min google search: Capacity: 425 cm3 (15.0 Imp oz, 14.4 US oz). Oil Level: 143 mm (5.63 in) From top of inner fork tube Fully compression without spring. Grade: Fork oil 10WT or equivalent. If that means anything to you. Taken from the 1987 FZR1000 service manual Quote Link to comment Share on other sites More sharing options...
Bicycle Repairman Posted March 3 Author Share Posted March 3 Thanks for trying. The '87 fork is completely different. '95 was the first year the KYB USD (upside down) for was used. I have a manual for earlier models but not the '95 supplement. Hours of scouring the interwebs has turned up nothing. Quote Link to comment Share on other sites More sharing options...

Moderator Snakebite68 Posted March 3 Moderator Share Posted March 3 Interesting, everything I'm finding is that the FZR went out of production in 1994... Quote Link to comment Share on other sites More sharing options...

Bicycle Repairman Posted March 4 Author Share Posted March 4 I believe 1995 was the last year. Thank you, Neo! That's exactly what I needed. I'm not sure what "Preload Adjuster 0 mm Range" means though. My forks have adjustable preload. 1 Quote Link to comment Share on other sites More sharing options...
NE0 Posted March 4 Share Posted March 4 I would say "Preload adjuster 0 mm Range", suggests( and i'm no expert) that it's wound to its stop for the level to be taken, then wound out to 20mm standard preload. Thinking about it, I believe its just stating that all the readings are taken with the preload set to zero: for the travel to be 88mm and sag, well....that's my interpretation of it, but i don't have it in front of me, however, i think its going to be something on those lines. It's just a reference point for all the specification figures to apply. Quote Link to comment Share on other sites More sharing options...
Bicycle Repairman Posted March 5 Author Share Posted March 5 If I'm interpreting correctly, the level is measure with springs out, stanchion collapsed and adjuster full out. (0 mm preload) Quote Link to comment Share on other sites More sharing options...
Bicycle Repairman Posted March 9 Author Share Posted March 9 I finally found a downloadable service manual that covers the 1995 with the KYB USD fork and figured out how to free the spring from the damper rod. Of course it requires a special tool that can easily be improvised with some plastic pipe and a washer but since the seals can easily be replaced without disturbing the spring, I decided to simply wash everything with Maxxis Suspension cleaner and call it good. Rather than using air space to measure oil, I used volume. I put in slightly more than 16 US ounces in an effort to stiffen the compression a bit. I also used 15W oil. I won't bore you with all the work, time and money I put into this project but it was a fight at every turn. Now the bike that had been "stored" for 29 years with 162 miles on the odometer, now has 168 miles on it. Tomorrow, much more! https://www.facebook.com/bicycle.repairman.75/ 1 1 Quote Link to comment Share on other sites More sharing options...

Bicycle Repairman Posted March 12 Author Share Posted March 12 So the next day I rode it to our local moto enthusiast hang out here in Tucson, Gear Shifters, and the owner immediately invited me to submit it for curation in the 520 Moto Show presented by Iron Horse Motorcycles (shameless plug). I didn't have to think about that too long. It now has a little over 200 miles on it! I think the fueling is not quite right though. The pilot jets are for Portland elevation around 400 ft. give or take and i'm now at over 2200 ft. Or maybe the fuel pump is gunky or maybe the fuel filter is gunky. In any case, I still have some fueling issues to work out. Other than that, I feel a rock star riding it!
