Friend of mine just acquired a decent condition 84 with 19,000 on the clock. Forks are a leaky mess Brakes are saturated with fork oil Tires are garbage (IRC) Owner swapped out glass fuses for blade type. Looks to have Toomeys. Clutch cable needs some love Handlebars are in a weird position. (I dont remember them being so cramped) Anyways... my buddy wants to just keep it in a safe clean rideable original condition. Thinking a set of pilot activs for the 18" wheels. 110 & 120? Need some guidance on the stock forks/rear shock. Were there any decent rear sets? Amazing what 30+ years does to your impression of the model...lol.
Conti attack 100/90 front 110/80 rear. Run the attack R's if you can get away with it. Fork seals are easy to do and available from Yamaha, but can be tricky if you don't have the right tools. I always just send all of my stuff to Traxxion Dynamics Clutch cable still available from Yamaha but I always get stuff like that from Economy Cycle. Contact Michael Morse at Vintage Brakes. He offers modern compounds in RZ shapes. I run them on my racebike with the stock rz calipers and mc and it lifts the rear off the ground easily. Jim Hinshaw at Fast From The Past offers Tarrozi rearsets that bolt right on, look cool and are solid.
Is he looking for parts? I'm turning mine into a hybrid so I have everything fork, brake, swingarm and wheel for sale...front and rear.
