I also think it might be a replica... too "clean" for a race bike - not too many scratches etc.

Race bikes have marks all over them when you get up close from people rushing on them when wrenching.

Also no pictures of the all important dry clutch...

Those cams have a lot of duration but not a lot of lift - I would expect at least a .400" lift - those look to be less.

Racers NEVER show the insides of there motor to anybody as a general rule... all the stuff that Muzzy did at that time was purely R&D also... I would expect a lot more trick parts on the inside as well - don't see anything top secret in those pics...

Taken a closer look at that head... there is no pathway ground for large cams (+.390") so I would suspect those cams to be around .360-70"... plus those look to be stock retainers - you would expect Ti retainers on a race engine.

That bike also has street tires on it...

Anybody who owns the "Wayne" bike would keep it original... it would be a museum piece.

indeed, there are couple of details that dont match, for instance, no race bobbins on the swingarm. but for sure there where quite a few works bikes built in those years and with different setups and solutions. if its a replica, then this guy did a hell lot of research work AND fabrication....

in any case, nice reference for my gpz race bike build :)

Something in the recesses of my memory tells me that the genuine racers had sandcast cylinder heads. Or did I dream it...

From the link Tri posted:


The majority of those great old machines would seem to be gone. Take, for instance, Kawasaki's early 1980s Superbikes that won three U.S. Superbike titles in the hands of Eddie Lawson and Wayne Rainey. While the Kawasaki team fielded several riders most years and those riders each had two bikes, exactly one—and only one—motorcycle survives from that period. The AMA museum has in its clutches Rainey's 1983 championship-winning GPz750, but the factory KZ1000 S1s from 1982—which were raced in Formula One in 1983—were chopped up and destroyed with the engines sold to Vance & Hines when Kawasaki exited Superbike racing in the US at the end of the 1983 season.

meant to put this here

you know just for conversation sake...look how sprung that bike is...even with what appears to me to be a smaller rim up front...and even though he may actually be accelerating at that point...even the rear is tall imo...

if you back page to the shot i posted of him tracking leaned away from the camera (a famous and commonly posted shot) even cranked over you can see the travel left in the front end.....

in both pictures the bike appears imo either weirdly set up or tall or over sprung compared to the average race bike...compensation on Muzzy's part im sure for trade offs to win and not drag stuff.....

just a nod to what those era top shelf components needed to handle at full boogie.....

seems our hybrids lately are slated forward or drooping sagging in comparison.

pictures are only pictures and i'm not saying it means todays forks need ride so high,but still...the engine placement in these double cradle frames and the amount of clearance under the engine is a big factor in med corner behavior and those two pics really show the amount gained by lifting the double cradle frame and engine together up some





not that it matters much...this is one heck of a gpz 750....but i had a feeling it was a copy...

here are a few pics of one of the bikes..remember it evolved i believe constantly and was in a state of transition from track to track..
also it was crashed i think and re-done pretty heavily a few times

it doesn't suprise me that most of them got destroyed when your racing a bike it is a tool not something that you would get nostalgic over at all, at least at that moment in fact most guys that are racing use things up, change things around, including complete bike set-ups most of us that do race and are somewhat serious about it would have no problem for example cutting off a steering head and changing the angle, going from a wet clutch to a dry clutch back to a wet if worked better when your racing nothing is sacred it's all about making the bike work better and when comes right down to it winning,that's all that matters.not whether you have left something for posterity. my race bikes i have changed so much on them i can't even remember how they looked when i first got started unless i find pictures from back in the day i'd be hard pressed to duplicate it. it's really the enthusiasit's that pay attention to whether a bike had matching brake calipers or the switch gear was exactly authentic.not very often will you see racers caring about these details. i guess that's one of the reasonsi've never been into the whole resto thing like alot of people are i just tend to think of my bikes as tool's used for a certain job.
