Genesis Of A Racebike - IT LIVES !!!!!

Here are some photos of the first bike to be built this year. Apparently February has been renamed "Build a Superbike Month" :D , so its time to spin some spanners. This is the Forgotten Era bike I intend to race in the PCRA Champs later this year......

Frame - 1980 Z750. Some mods already done, all excess brackets, etc, ground off. Further mods - engine mounts to be modified to suit motor, further bracing on frame tubes.

Wheels - Class-legal 3.5x17 front, 4.5x17 rear. Unsure of heritage, I *think* they are GSX-R rims from the early 90's.

Swingarm - Box-section aluminium swingarm, modded as required.

Motor - 1980 Z1000J motor - 1170cc capacity, otherwise stock ... :wink:

Forks have not yet been obtained, have rear brake but no front rotors or calipers at this early stage. The visit to PI last week gave me a few ideas on what is / isn't legal :shock: .

This baby should hit the scales around 180kg dry, and those old 2-valve donks can put out a reliable 130-140hp. It should be a weapon.

Yes I have been a bit slack............did a proper trial engine-fit today, looking good, top front mounts line up , lower fronts will need to be moved, and rear mounts line up as well...........ya just gotta love KHI 'economies of scale'.... :lol:

Already changed the swingarm, I had forgot about the GSX1100 number floating under a bench, its a better fit and lighter as well, so its going to be used instead. Used some old shocks, fitted the rear wheel up to the s/arm to check the chain run............well I'll be buggered, it lined up straight :shock: :lol: one less problem to worry about.

This bike really will be..........."......you know Maxy.........a piece frome here.............and a piece from there..........." :wink:

Hey Gos, get an early Ceranni front end from a 860 or drama ducati, word is that R6 cartridge goes in pretty easyand works damn well, "alledgedly" is what Leo Cash uses in his Honda up here.

:shock: Cheers roo, I know a couple of the post-classic guys down here with those front ends.........

I am going to do a number on a set of forks that are 'visually indistiguishable' from the forks used on the TKA Z1000SR - the endurance racer that was ridden by Gregg Hansford in the Coca-Cola 800 at Oran Park in March 1980. The forks on that bike were 40mm, used twin horizontal pinch-bolts on the lower legs, and look *identical* in every respect to some forks used later on by KHI on a particular road bike.... :wink:

At the moment, there is some issue with twin pinch-bolt lowers in Period 5 racing, all the fast punters at the Island Classic a couple of weekends ago were running modified lowers, so that only 1 pinch bolt was used...... :? :? It beats the shit out of me, I cannot recall *any* forks from the era (1972-1980) that used single horizontal pinch bolts - except maybe some old Marzocchi's or something ?? Maybe it was the fork lowers used on some of the early Bimota's that are deemed as *era-specific* ...... :?
