TO GET A LOG BOOK FOR MY BIKE, I AM ASKED WHAT FORKS IM USING. MANY GSX1100 RACERS ARE USING GSXR 41s, WITH THE ANTIDIVE MILLED OFF AND MUST KNOW OF A PRE 1980 MOTORCYCLE THAT HAD SIMILAR LOOKING FORKS. I NEED TO KNOW WHAT PRE 1980 MAKE AND MODEL THEY PUT ON THEIR FORM, TO BE ELEGIBLE AND GET THE BIKE THROUGH. IM STUCK ON THIS QUESTION, AS I TOO AM USING MODIFIED GSXR 41s AND CANT GET IT ON THE TRACK UNTIL I FIND THE ANSWER. IF YOU HAVE A GSX1100 WITH THESE FORKS, PLEASE HELP ME GET OUT RACING, BY TELLING ME WHAT THEY ARE COPYS OF. THANKS IN ADVANCE, WHITEY.

ROGER. GO AHEAD AND PROTEST ME THEN YOU TOOL. THEY ARE VISUALY THE SAME AS PERIOD 41s AND ARE BEING USED WITHOUT PROTEST BY MANY NSW RACERS. THIS PROTESTING CRAP IS REALY TAKING THE FUN OUT OF BUILDING UP MY RACEBIKE. ALL I HEAR ABOUT IS PEOPLE MOANING AND THREATENING EVERY ONE WITH PROTESTS FOR STUPID LITTLE THINGS. IF YOU KEEP THIS ATTITUDE UP YOU WILL FRIGHTEN EVERYONE AWAY FROM RACING P5 BIG BORES AND WERE MEANT TO BE ENCOURAGING PEOPLE TO COME OUT AND HAVE SOME FUN. WERE NOT PLAYING FOR ANYMORE THAN A TROPHY AND SOME FUN ON A WEEKEND. THERES NONE OF THIS HAPPENING IN SERIOUS MODERN ROAD RACING, WHERE LARGE CASH AND SPONSORS ARE INVOLVED, YET HERE, PEOPLE LIKE YOU ARE SO SERIOUS IN A SURPOSED 'FUN' CLASS. LIGHTEN UP ROGER.

and how many people are not racing because they can't afford to do the mods and are too slow because their bikes handle like well set up pre 1980 bikes ??????

GIDAY POPEY. DO I KNOW YOU FROM AROUND ADELAIDE AND AT THE TRACK ? ARE YOU A P5 BIG BORE RACER ? I WAS RACING A TD3 250 P4 FOR 12 YEARS IN THE 90's. I SEE YOUR POINT ABOUT AFFORDABILITY, BUT UNLESS YOU HAVE PLENTY OF MONEY, YOU WOULDNT BE ABLE TO AFFORD TO RACE MUCH AT ALL WITH THE SOARING COSTS OF THE SPORT NOW DAYS. A SET OF $200 FORKS DIDNT HERT THE HIP POCKET TOO MUCH. I JUST DONT SEE THE POINT OF SPENDING A FAIR WOD OF CASH BUILDING UP A BIKE WITHOUT THE GOODIES THAT THE POINTY ENDERS ARE USING. ID NEVER HAVE A CHANCE OF WINNING ON A STOCK WELL SET UP BIKE AGAINST THESE OTHERS THAT ARE USING ALL THE TRICK STUFF. IF I COULDNT AFFORD IT, I WOULDNT HAVE IT. BUT BY PROTESTING ANY ONE WHO 'CAN' AFFORD THE GOODIES, WONT HELP ANY EITHER. ROGERS COMMENT REALY GOT UNDER MY SKIN AND I HAD TO SAY SOMETHING, HENCE MY NOTE.

glad to see the response from both side of the fence, the comment is meant to question what is a period racer?? not what bits you can make fit from a later period. I still do not have a log book for my bike as it has taken a long time to finish as I am trying to make it look like a racer from the era. If you read my comments over 6 mths ago you would see that I question why CB1100r seats and alloy fuel tanks that look nothing like an original are allowed on GSX's, and why late model GSX 1100 motors are also being used. I thought the rules were there to provide a level playing field (ha ha)And as for being serious, I have always raced for fun and been pretty good at it, but I am not going to throw dollars at a bike which may as well be racing in a different class to your "trick" ones. I suggest you read line 6-8 of your own reply!

Roger ,the cut off date for P5 is 31 December 1980,last time I checked with Suzuki the GSX1100E (1075cc) was released in about October 1979.Which makes it eligible by 14 months.Thats why we can race them!!!Katana donks arnt allowed and that sucks.
Youll find to that the motor was never changed in style apart from the Kat versions.
As for protesting,its only a $5 trophy your protesting for.Why?Whats the purpose of keeping the guy off the track?

Here is a little story for ya,
A certain competitor had floating discs on his P4 outfit,well after people had a piss and moan about them he decided to change them back to solid mounts.
Thing is though he had a set made thru a friend of mine and now not only are they "in period" the disc material that was used is a far far better grade of iron than the steel floaters he originally had.
Better heat dissapation is a big bonus,Ive got 1 on my GP bike and must say its freakin scary under hard braking goin into Crash Corner with the rear wheel waving to others behind you.
The outfit looks as if it handles much better under brakes and will give any P5 outfit a run for its money under hard braking.
So all I can say is be vary careful about protesting as sometimes it can backfire bigtime.
Cheers
Neill

Whitey,

I am a newie to Historics (recently moved to Mt. Gambier from the bush)currently building my first bike to learn racing on, it is a CB360 twin, I also assist the scrutineer at Mac Park events so have an interest in eligibility issues.

FWIW my whole investment in the 360 will be about $1800 ready to race, it may or may not be competitive but it will be fun.

The only bike I can come up with off the top of my head with 40+ mm forks is the Munch Mammoth, now all you have to do is find a set, the bike was released in 1967 so is good for P4 as well.

HI THERE POPEYE AND NEIL, THANKS FOR YOUR SUPPORT ON THE PROTESTING ISSUE. IVE SINCE FOUND OUT SEVERAL BIKES THAT USED 41mm FRONT ENDS THAT ARE 1980 AND EARLIER, SO I WONT BE GETTING IN TROUBLE NOW. BACK IN THE 90's WHEN I WAS THIN, I USED TO DO QUITE WELL ON A NATIONAL LEVEL AND FOUND THAT TO DO SO, REQUIRED THE USE OF THE SAME MACHINERY AS THOES WHO WERE WINNING ALL THE TIME. THIS IS WHY IVE BEEN DOING MY HOMEWORK AND SHOPPING AROUND, FOR THE REQUIRED PARTS TO BE ABLE TO BUILD ANOTHER 1/2 COMPEDATIVE RACER, AS IM WAY TO HEAVY TO BE RACING MY TD3 250 TO ANY VICTORY NOW DAYS. BUT THATS WHY I ENJOY RACING SO MUCH, I ALWAYS GO OUT TO TRY AND WIN AND TO ME THATS THE FUN PART, EVEN IF I DONT (WHICH NOW DAYS IS MORE LIKELY) WIN, I KNOW IVE BEEN ON EQUAL MACHINERY AND THOES INFRONT, RODE A BETTER RACE THAN ME. NOT TO MOAN ABOUT "I COULD HAVE WON IF I HAD AS GOOD A BIKE AS THEM" MY PLANS AND IDEAS WONT AGREE TO ALL, BUT EVERY ONES DIFFERENT, AND THATS GREAT. GREAT TO SEE A GOOD RESPONSE TO THIS THREAD. P5 IS ALIVE !!!.........WHITEY

My gut feeling is that you are trying to get away with something that is not kosher. I may be wrong but when I was researching details for the Pommy and NZ Forgotten Era bikes to front to Phillip Island, fork diameter differences was one of the issues.
I have checked, GCR's 13.4.4.2 there is no way that you will get a log book with fat forks that dont look like the real thing. There are plenty of forks available that are 39mm and 40mm why give yourself the agrevation. Do you realise that Wayne Gardiner won a few world Champs with 39mm forks so why the need for bigger ones.
Any existing fat forks either must look like an original from the period or they should not be on board and would have to be protested out, or observed by the eligibility scrutineers unfortunatley that is the way the system works.

FAIR CALL... IM BASING MINE ON THE RG500 GP RACERS OF THE LATE 70's AND 1980. THESE ARE THE SAME BIKE THAT HAD THE FLOATING FRONT ROTORS THAT SOME PEOPLE ARE MAKING REPLICAS OF. (ATLEAST THEYRE SUZUKI ITEMS GOING BACK ON A SUZUKI P5). THESE BIKES I HAVE PICS OF AND MY FORKS WONT LOOK ANY DIFFERENT TO THEM. THEY 2 ARE 41mm DIAMETER. IM NOT THE ONLY ONE "TRYING TO GET AWAY WITH FAT FORKS", COZ IF YOU LOOK IN THE PHOTO SECTION OF THE PCRA NSW WEB SITE, YOUL SEE ALOT OF GSX1100s WITH THE SAME FRONT ENDS, ALREADY LOG BOOKED AND OUT RACING! (ALSO WITH HONDA CB1100R SEATS) NO ONES PROTESTING THEM. ANYWAY, THERES ANOTHER PERIOD SET OF 41s, AND THATS THE HONDA LEADWING OF 1980 (OR BEFORE) SO IVE HEARD. SO WITH THE HARLEY ONES, THE RG500 GP ONES AND THE GOLDWING ONES, THATS THREE ELEGIBLE 41mm FORKS WE KNOW OF AND THERES BOUND TO BE MORE. IM ONLY USING THEM COZ I GOT 2 SETS SITTING ROUND AND SAW THE OTHERS USING THEM AND THAUGHT THEYD HAVE TO BE BETTER THAN THE 37s. IF ITS ALL TO HARD IL USE MY 37s. STUART LOLLYS A GOOD INDICATION OF HOW WELL THE 37s WORK. BUT THEY DONT LOOK AS "RACE BIKE" AS THE 41s! KEEP UP THE FEED BACK TO THE THREAD.......CHEERS, WHITEY.
ps. IL BE AT WINTON EARLY NOVEMBER IF YOU WANT TO MEET 4 A BEER.

there is a difference between the 1979/1980 gsx motors and the 1981 and later versions. different shaped rocker cover and different number of bolts (24 instead of 20)holding it to the head. this later version with 24 bolts was introduced as the 'black motor' and was originally released as powering the Katana in 1981. now as all major and minor katana parts are banned from p5 racing, isn't the motor listed as a 'major part' in the rule book?
but common sence prevails and this 'minor' infringment is overlooked by the powers who aprove the log books...
unlike other 'minor' issues such as brake calipers.
anyway, Kayaba had 43mm fork legs avalible in 1980, though of useing them?
 

 
There are those who do, those who used to do and those who never did..
why is this 3rd group always trying to convince everyone they know best?

WELL IVE MODIFIED THESE THINGS NOW SO THEY ARE EXACT REPLICAS OF THE RGB 500. PROBABLY COULD HAVE LEFT THEM STOCK AS EVERY ONE ELSE ISNT BOTHERING TO MAKE THEM LOOK MORE GENUINE AND THEYRE GETTING AWAY WITHOUT PROTEST. I JUST WANNA HAVE SOME FUN. WHITEY
