Shopping list for 2013 track season

The deed is done, you be the judge. The video below has three parts:

Part I: Demonstration of the drag with the stock rotors (semi-floating). When the brakes are hot, the drag is 2 times worse, almost impossible to spin a full turn (not demonstrated).

Part II: Free spin with removed calipers.

Part III: The wave washers on the rivets which hold the rotors to the carriers were removed. The one and only other difference from Part I is that I changed the tire, which is completely irrelevant for the test.

I forgot about this thread. I got a whole bunch of internal engine and transmission parts involuntary added to my list thanks to blowing up 4th gear at Grand Bend. Currently using a stock engine that i previously built as a backup. Replacement gearbox is out getting cryo treatment right now. I don't want this happening again.

This is an old thread, but just wanted to add this in case somebody ever comes accross my post.

Even though the mod performed well, I decided I don't like it for a couple of reasons: 1) it was really clanking (much more than floating Brembo rotors), and people were really looking suspicious at me all the time; 2) The rotors seemed to move front to back a little bit (apart from the intended side to side), so I chickened out and bought a set of the same rotors (used but in great condition), which I just installed. Bottom line, i regret doing the mod, although I don't have specific proof that the mod was bad.
 
Can anyone tell me the advantage of using a SBK tail vs. a tail that utilizes the stock seat?
Is it a weight savings thing or what?

The others with first hand experience should chime in, but from what I hear with the SBK tail you get a better feel for what the bike is doing. The stock seat softens (blurs) the feedback. I wish I went with SBK tail myself...maybe next season. Good luck!
 
You can get a bit too much information, too... it takes a while to acclimatize.
 
What corsara he said. Riding two different bikes this season on with a sbk tail and on without I much prefer the sbk tail.

I also find it to be (depending on the seat you put on the SBK) less wide than a stock seat
 
Its also easier to move around with a stiffer seat pad. You dont need to lift your butt out of the seat to move side to side.

It's interesting that you mention that, I find myself rising a little to slide off the bike with the stock seat... Glad to know that this will help.
To a novice track rider, I'm sure I won't be able to 'feel' much from the SBK tail but I will make sure to grab it if I decide to convert my GSXR and try and learn what the bike is doing.

If I do grab a track ready bike, the SBK tail will be a bonus...

Track bikes are popping up more now and I'm getting excited, I love bike shopping!
 
Another question as I continue my hunt for my next track bike..
How reliable are built motors?
I'm sure it varies from build to build but generally speaking, how soon do they need to be refreshed/rebuilt?
Are they more prone to breaking down compared to a stock motor?

Rebuild every season, f what anyone says that's my rule. Having dealt with this recently and a list of parts that would make you puke I don't take chances now. Gsxr new valves every two years max and retainers every season, these are known failures (depends on the amount you ride obviously). I'd want to know who built it, what mielage/races are on the build and the extent of the build before I'd consider a built motor again. Just simple cams and a valve job isn't really a built motor but any track bike should have all these things considered anyway.

Varies all over the map. Some engines have known weak points. A built engine could fix that issue or make it worse.

Yeah, that's what I figured... I put a deal together on a 2006 GSX-R 600 with a stock motor and some aftermarket bits, the expensive parts are obviously left up to me. lol

Even with a stock motor valves ($$$) and retainers need to be replaced if the bikes done heavy track duty. Retainers at the absolute minimum. This is pertaining to gsxr's, other bikes are different but may still have the same issues.

Not yet, there is still one more SOAR race weekend. 2013 is not over yet when it comes to upgrading :)

Soon
