Rotor thickness for 88 FZR1000?

[Mark Olson]

hey Monkey ,

you can sell the fzr rotors on ebay and recoup the cost.

While removing the rotors off my front wheel, I rounded out 2 rotor mounting bolts. Anyone got a spare pair?

I was removing the rotors so I could get the front wheel refinished to match the rear wheel. As in gloss black.

Thanks in advance,

CraigO

Hi Mark,

Just want to let you know I did try in earnest to get the rotors measured today but ran into walls in 3 separate shops. I will venture out again tomorrow to get this done for you. I didn't even get my tire off and the rotor bolts removed. But I got a clue on how to do it myself. I just need a small grinder to cut slots into them and use a big flat blade screwdriver.

Will get back to you tomorrow on the rotors.

If you grind a slot into the heads of the bolts probably you will destoy the bolts further and or ruin the tip of the screwdriver. You need heat to break the loctite bond. Try using a torx driver that is slightly too big for the existing hole. Heat the bolt head and using an old style impact driver, the kind you hit with a hammer,set it to turn couterclockwise, drive the torx driver into the damaged hole when you've got the bolt hot and it will spin out. I've removed many damaged allen bolts this way.

Here's a page from the '87/88 FZR1000 Yamaha service manual (my son has an '88) :  Also I have a set of front rotors off an '84 FJ1100, which measure 7mm+ if U R interested...

Thanks for the info. 4mm is consistent with the measurements I took. Still does not tell me what the low end is, of course the rotor is over diameter and is now a mute point. I will keep your offer in mind if the other two offers fall through, 7+ is better than my under spec rotors. I am starting to think that all you guys are really "Helpful Honda" sales guys. I have some forks that need polishing....

[Dads_FJ]

Sorry, my attention to detail lacks sometimes...  But what I don't understand is, if the starting thickness is 4mm, how can this diagram state the min as 4.5mm?  Shouldn't it be smaller than 4mm?

My web searches showed the thickness to be 5mm. Really? Half a mm and the rotor is toast? Or worse as you point out the difference between the two pages has the stock rotor starting out 0.5mm under spec.....Too much time spent on rotors I can't use. Thanks for the informative but confusing sharing of the pages from the manual (not your fault, not shooting the messenger). I will let you know if I want them rotors. Thank again.

Relax Monkeyman.

Uncork a zin or uncap a torpedo and revisit Dads FJ's and Arnie's posts.

FZR rotor standerd thickness 4 mm.
89-93 FJ   "              "         5 mm.
Max wear for either .5 mm.

More importantly, did you get the damaged bolts out?

I think I'll let you "polish your fork" by yourself but I'll gladly sell you some Honda parts.

Hey Mark,

My guy says that the rotors are at the max wear limit and in his opinion they are toast.  

Anyone want to buy some rapper bling? I'll mount the clock and buy the chain. $5000 obo.

Thanks! Option one tossed in the bin, options two and three are stock 86' rotors. Steve (Moparman) have you measured your rotors for any useable life?
And Dads_FJ has rotors at 7+mm offering enough life from now till past the rally.

What do you guys want for a set?

[Dads_FJ]

Kinda hoping you wern't going to charge me for taking them.
