ultralite

That SV ram air box that Mark is talking about should be illegal. Basically it's a ram air box that encloses the entire airbox, so since the airbox remains intact and stock, it's been deemed legal, at least by CCS Florida tech.

So with that thinking in mind those little "vented brake" ducts should also be legal in Supersport but they are not. Makes sense to me.

I would think though if you were to call a class Superstock then class rules should be closer to a stock machine. spersport on the other hand though loosely based on a Stock bike allows more modifications and additions to the machine.

We talk about grids getting smaller and blame it on the economy but grids have been getting smaller for a long time. it would be nice to allow older machines a fighting chance such as this Ultralight class and maybe give my FZR400 a fighting chance. I will put my plan together and submit it for consideration regarding my FZR400.

i just looked at the rulebook and I don't see any reference to liquid cooled 4 cyl machines in ULWSB.  Weird!  800cc Honda Hawks are OK, Ducati 800s are OK.  I think they should let you in on the FZR400 up to 490cc.  Same as WERA D superbike.  I also think WERA should boot the Ducati800SS out of D superbike but that's another forum...

800cc Honda Hawks are OK

Except that no one would ever do that. The limit for reliability sake is pretty much 700cc.
Sure, JD Hord has built a 90hp Hawk that weighs nothing, but it's chock full of so much unobtanium, nobody else is nutty enough to spend the money to build something like that.

There is a provision for the 4 cylinders liquid cool pre 87 up to 570cc, and the 87-92 up to 500cc. My thought though is that the SV once legal in Lightweight and no lower competed against the FZR400 which was allowed 560cc. Based on the concept of the SV now legal for Ultralight wouldn't it allow for the FZR400 with the same LW limits? That's the pretense I will work from. Yes I know it may be a grenade like the 800cc Hawk but at least it gives that option. I love those little FZR400s.

can a FZR 400 make 70hp with out being a time bomb?

[spyderchick]

yes.

[roadracer162]

yes.

...and yes. My stock FZR400 with total loss makes almost 60 hp. The other stock version with it's charging system intact is slightly slower out of the corners. With some mild work the FZR400 mill can make 70hp reliably but consider that the weight is the same as the SV. The SV can get out of the corner better than my FZR600 so I am sure it will certainly trump the FZR400 with no matter what motorwork the FZR has.

I know that I am of the minority still running and working on the FZR400. But it is what keeps me racing and not in bankruptcy court as far as my racing is concerned. A major drawback for the FZR racer is the puny 18" wheel on the back. There are no manufacturers building a race tire except for Bridgestone. Yeah sure there is the F2 wheel conversion but that costs money. My last FZR400 I was able to put together for $700 total and a Krylon paint job included.

$700....Seriously?

I would build one of those just to have a project to work on!

[Gino230]

better yet, let's build like 5 and have the FZR 400 cup. We can pick numbers out of a helmet to see which bike we get!

[roadracer162]

Funny you say that. I just bought another for $1000 that needs to be finished with bodywork. That will be my Vintage racer. That will make a total of three in the family with another two in the making.

Troy has been doing well on his FZR400 in the Premier class of Vintage against a varied group of competition. I am sure that Tash Zarvales will be gunning for him on that big Kawi 1000 at PBIR. The show to watch will be Henry degouw on his TZ750 and maybe John Long on his TZ750.

[Ducmarc]

another one ?   if john brought out his TZ 500 would that be light weight?

[roadracer162]

I am pretty sure John's TZ is "premier class" runing against the likes of a Kawi 1025cc.
