I'm building another set of wheels for my Speed Triple to use on track days. They'll have BT002's on Marvic rims. The issue of heat cycles and race tires vs street tires is confusing to me. I plan to use warmers with the BT002's just because that's what I've been told. What exactly is the deal? Race tires are more susceptible to degradation from heat cycling because a) the rubber compound has more plastisizer so they get softer but the additive gets consumed during heat cycles causing the tires to get hard?
the carcass is stressed during heat cycles and is prone to failure? c) warm tires are sticky right off the bat? Just curious and I can't find a good explanation.I will try to explain. 1 heat cycle can be your 20 minute session, or it can be 1 trackday.
20 minute session= You do your session and come back to your pit area, park the bike. Next session for your group is in 40 minutes.
1 trackday= You keep one set of tires either on the track or in warmers AND being monitored. NEVER keep a set of warmers turned on for more than 30-40 minutes w/o either going back on track or shutting the generator off. I say "shutting the generator off" as you would leave the warmers attached to the wheels to sustain warmth.
So, you can have 1 trackday and a set of tires with 3-7 heatcycles through them. OR, you can have 1 trackday with your tires having 1 cycle through them. The BT002 are a fairly good tire that should be able to maintain grip through 6-8 cycles with ME running them-that's the kicker. There is such a huge variable between riders and their bikes/suspensions/chassis set-ups that you will have to monitor things for yourself. Take notes and decide to pay more attention to your instincts and less on what you hear at trackdays.

Robert I dont have trouble moving around on the seat but its hard to get the upper body off the tank area. Bottom line I quess its not a sport bike even if it thinks it is.
Thanks, Joe
Hit it on the head there Joe- it is not a sport bike.

Read the books and take the California Superbike School, at least Level 1, at a track near you. I took Level 1 at the last Road America date. I camped nearby on my BMW R11GS and rode Keith's Kawi 600, stayed for the weekend of AMA Superbikes. ( Dang that Flea was a cutey!) Later that summer it saved my ass.
I was touring out West in Montana/Utah/Colorado, on my way to the Top O the Rockies Rally in Paonia Colorado. The end of a long day in the saddle nearly ended about 10 pm in western Colorado. Even with my high beams and monstrous 6" PIAA 520s, it was hard to visually differentiate the cardboard box that laid across my lane of travel from the rest of the night. I don't know if that box was full or empty, but I did not hit it as a result of lots of counter steering practice. Thanks Keith.

T3D/4 BHF
It's a hard right follwed quickly by a hard left. I think maybe it's the trees that get me in some sort of target fixation hex and the close proximity of the corner workers.
T5 at Road America
Coming down from 160-170 seems to get me in the flat-I over brake, way too early, and then compensate scrubbed speed with too much throttle, unsettle chassis and flunk the turn in. It's either hilarious or painful to watch, I'd imagine. I should be writing about this stuff more often-helps to sort it out somewhat.
Will CSS ever go back to Road America?

125 gp bikes are in their own world, nothing like them.
1984 gpz 550 at the schools in 85 were awesome.
Raced an rz-350 also, excellent bike, loved it.
I was interested to see what riders thought was a good handling bike. The modern 600's are fantastic, but there were some older bikes that were excellent packages. One friend had an old Guzzi V-7 Sport--disk brakes and all. He loved it, but I hated it.
I'll be interested to see what else we get up here...
I had a Ducati ST4s for about 20k miles. Had the Ohlins rear end and TiN coated fork legs. After a while of twiggling with all the adjustments I had it down for sport day ride adjustments vs. casual/soft city duty adjustments. I guess the reason I liked the handling so much was the chassis never seemed to get out of shape too awful badly as I progressed with the machine, speed wise, in the corners. I always wonder why more manufacuterers don't make the sub frame as one piece with the main frame stays, as Duc does, rather than a bolt on piece that has so much more flex...Anyone?

I'm thinking about signing up for the Dec 11. day course at Laguna Seca.
Here's the thing though: I've never been on a track.
I have my motorcycle license, have taken the MSF safety course and have been riding a cruiser (
) for a few weeks on the street. Never really been on a sports bike 
I grew up on dirt bikes though...Am I going to be in over my head? Do the day courses teach fundamentals (hand signals, track etiquette etc.) Or am I going to be a slug on the track, holding everyone up?
Thanks
Relax, have fun, keep your ears open. Read TOTW if you can, before the learning day. Level 1 is great and don't worry about being slow.

One pointer is simply to practice. Even practice on a dirt bike helps and does good. Smooth transition between clutch lever release and increase of throttle. Also, watch the starter BEFORE your race-see how quickly or slowly they go with the flag.

This has always been in the back of my gourd; If I have a better understanding of scientology and Mr. Hubbard's body of work will it help me to better understand some of Mr. Code's writings?
Here is where I am at; I have read and reread TOTW several times. Have completed Level 1 when CSS was last at R. America. I have started racing in CCS again as an amateur. At this point I am on an indefinite lay off from work, so I have additional time to read. However, I am finding that Keith's new writings are not flowing for me, as a reader, like TOTW I did. I am interested in Dianetics and have picked it up from the library. Perhaps I am resting on these minimal accomplishments on the track? I do not want to get caught in the past and would like to continue moving forward in racing and teaching. Does this make sense to some instructors or students who have recently discovered scientology? TIA,
Todd

Road America, I'd say, nothing like digging out of Kanada Korner heading up to the bridge, blind.
