4&6 racing

Hey everyone. I found you guys after trying to figure out just what exactly I just bought. I picked up a 1997 Ninja zx6r that was built by 4&6 racing, which is what brought me here. I saw that several of you guys were quite familiar with them and they are unfortunately no more. So what makes me wonder what I really bought is.....

1st The bike weighs in less than my 2012 Daytona 675r. It's wet weight is only 381lbs.

2nd The rear swing arm has been welded up and reinforced

There are some things that don't make a lot of sense as well. For example if you go through the trouble of taking 60lbs of weight off the bike why would it have stock breaks. Unless those were scavenged somewhere between the original build and now.

Anyway I didn't know if maybe someone here may be able to give some insight.

Not to familiar with them personally, never had them do any work on my bikes.

My guess is your guess on the brakes. Probably took them off for another bike at the when they "retired" this one from racing. Old racebikes are hard to know whats been done unless you bought it from the guy who built it and got a list of stuff done. Hopefully someone here may know the bike.

I'm not crazy, my mother had me tested.

I raced one of these back then, and most of that stuff is probably because it's an ex race bike, and they were notoriously flexy, to the point of cracking frames. Better handling for that bike came in the form of reducing flex, and I'm guessing that was one way of making it better. Or it cracked there, and it was fixed. Brakes as per supersport rules had to be stock at that time. The weight reduction could come from many places, including the exhaust, gas in tank, bodywork, shock, tires, battery, etc.

Lol it doesn't take a rocket scientist to figure out who the serious players are when it comes to straight super-bike dedication lol!! I am new, but already can tell you have a great passion, you have been in a few threads I been reading. Can you get me in for a KTM club race kit installation as well as a tune? I sold my s1000rr over the winter and picked up a rc8r that being said I only have about 250-300 miles of seat time, I think it has great torque, but the BMW was definitely one up on the hp

* Edit * - I could write an essay about how much better of a bike the rc8r is, but I din't want to go too much off topic

** Edit Edit ** - It just let me PM you, did not let me before, PM'd

Judging from the way they boxed in the swing arm I'm sure it was to reduce flex.
So you would guess it was an old supersport bike then? It's story was that it was raced AMA but I didn't think supersport allowed for a lot of modifications. The diet it went on and having the swingarm doctored up the way it is made me question if it could have been. It would be interesting to know it's "story" but I'm guessing that's a long shot.

Technically, the rules did not allow those types of modifications to the swingarm or frame, but without knowing the full extent of the purpose of the bike, it could be a mutant of supersport/superbike parts at this point. If I had to guess, it was definitely raced at a higher level by someone who would appreciate and need those mods, so most likely AMA.

Thanks bro! Yeah I actually already have the club race kit, it is just basically an exhaust, with a thinner head gasket, SAS removal and a filter. Lucky I am part of the forums and did my research not to get their other 2 " super " kits as they do absolutely nothing besides add risk to failure. After countless hours of data it was clearly proved on the KTM forums that the " KTM super bike kit " was complete marketing propaganda and a complete waste of an additional 8k+ with no performance gains and reliability being favored by the simple " club race kit ", KTM should actually be ashamed of themselves. The " special cylinder " they speak of is just a freakin oem cylinder that has been flow tested out of 10 units ( so basically they take 10 STOCK cylinders , flow test them, and shove the ones with the best flow in the kit and call it " special " ). The KTM club race kit is phenomenal, but they really got super pathetic with the other 2 options lol.

I woke up in a hotel and I didn't know what to do
I turned the TV on and wrote a letter to you
The news was talkin' 'bout a dragnet up on the interstate
Said they were lookin' for a Cadillac with Tennessee plates

Since I left California baby, things have gotten worse
Seems the land of opportunity for me is just a curse
Tell that judge in Bakersfield that my trial will have to wait
Down here they're lookin' for a Cadillac with Tennessee plates

It was somewhere in Nevada, it was cold outside
She was shiverin' in the dark, so I offered her a ride
Three bank jobs later, four cars hot wired
We crossed the Mississippi like an oil slick fire

If they'd known what we was up to they wouldn't 'a let us in
When we landed in Memphis like original sin
Up Elvis Presley Boulevard to the Graceland gates
See we were lookin' for a Cadillac with Tennessee plates

Well, there must have been a dozen of them parked in that garage
And there wasn't one Lincoln and there wasn't one Dodge
And there wasn't one Japanese model or make
Just pretty, pretty Cadillacs with Tennessee plates

She saw him singing once when she was seventeen
And ever since that day she's been living in between
I was never king of nothin' but this wild weekend
Anyway he wouldn't care, hell he gave them to his friends

Well this ain't no hotel I'm writin' you from
It's the Tennessee prison up at Brushy Mountain
Where yours sincerely's doin' five to eight
Stampin' out my time makin' Tennessee plates

There may not have been a whole lot of (economical) options for brakes back then. It's not like today; back then mods were pretty starightforward and simple - less weight, more power, proper suspension setup. No cartridge forks, super fancy shocks, slipper clutches, mater cylinders, etc. Plus, if they lightened the bike up that much, the stock brakes would have worked that much better.

FWIW, the main guy at 4&6 was Jim Rasheed; the shop went under about 5 years ago. Around that time, Jim was also affiliated with Safety First racing, and head tech inspector for AMA roadracing for a couple of years. Jim knows a ton about racing; when he was Todd Herrington's builder and team captain, they were the last privateers to win an AMA Superbike race.

Ken, it looks like you got a new gloryhole mate! Yes new guy, he does have a great passion - for tight wet holes!

I am new, but already can tell you have a great passion, you have been in a few threads I been reading.
