"How to toss ur bike b4 tracktime" or "How not to scrub in your tires"

Posting in hoping that someone will learn from my mistake yesterday..

Showed up bright and early this morning for tech inspection for [email protected] Thunderhill today, right go thru inspection flying colors. Riding back to my pit, thinking hmm I'll weave a bit just to scrub off that release skin from the new BT-001's.
Made about 5 or 6 very shallow weaves and LOST the backend just 200 ft from tech inspection. I guess the bike decided it wanted to toss me right on my ass without warning, better yet I've sprained the hell outta my left knee, my ass hurts...look over at the bike and that precious fluid is pouring out of the stator cover which now has a large crack / hole in it.

Thanks to the guys and who picked up my "bleeding" 929, and helping me up, and Doc Wong for helping me back to my pit. Needless to say, I didn't get one lap in..no spare parts for the 929, and my knee was in no shape to straddle the bike. I should have known better than to weave, but seriously..they were very shallow, speed maybe..maybe 20mph. I've done this b4 with rennesports with no problems, so I wonder if the BT-001's are more twitchy during the breakin period or what?! I surveyed the scene briefly, no sign of oil or contamination in the pit area - back end just slid right out from under, and I was on my back before I could say "oh ****". Honestly, I think I would have dumped it during those warmup laps if I'd made it out to the track..pretty cold up there today (45-50F), and started to rain after the first session..some people lost it at the Cyclone, and the Ambulance was sent out for another rider at T6 or so. We packed up and left at that point, no use in sticking around, can't ride and my knee is killing me, most of all my pride and embarrasment of dumping in the pits

Anyway, comes down to an expensive lesson in cold / wet weather new tire "break-in". After 20 years of riding I can now join the ranks of "those who have"

Feel free to chime in as I've beat myself up pondering "what if's" more than any of you can...so constructive critisism is welcome.

Sorry to hear, and I feel your pain on the knee. I had my F2 land on my right knee about 25mph. Swelled up to 2x it's normal size, and I was limping around for weeks. Hope you get well soon.

Man that blows Joachim! Heal up quick. As far as tire break in is concerned...best advice I was given is not to swerve....instead on your first lap, while cornering tip it in smoothly and not too deep...next corner tip it in a lil more, and progressively tip it in deeper for both sides of the tire as you go around the track...second lap go with some hard accel and good braking to put some heat in them tires.

Re: "How to toss ur bike b4 tracktime" or "How not to scrub in your tires"

Yeah, it's my understanding that accel/decel affects the heat of the tire more than weaving. Sorry to hear you took a spill.

Is a paradigm worth 20 cents?

Re: "How to toss ur bike b4 tracktime" or "How not to scrub in your tires"

Were they brand spanking new tires?
If so i would have run some sandpaper over them to scuff them up a bit and to remove the release compound.

I've also learned not to break in a new tire at a trackday.

Be fast or be last.

Re: "How to toss ur bike b4 tracktime" or "How not to scrub in your tires"

The cold temps are probably as much to blame as the mold release goo. I have my own embarrassing story about that.

Sorry about your mishap. Hey, it's gotta be better next time.

What better environment to break it in?

Watch the pros. They roll out on to the track with shiny new rubber all the time. Usually gets scrubbed in after a lap or two...

edit: One caveat...they do use tire warmers.

I mean, brand spanking new street tires. Cold day, standing water, new track (for me), and wrong tire pressure == 1 miserable trackday that ended half an hour after it started.

I learned a good lesson that day. Don't get cocky staying on the gas when I don't know the turns so good. But the cold slick-ish tire contributed to my lowside, as I did NOT touch the brakes.

I am sure the pros have someone in their crew in charge of tires that would remove all the release compound and have them race preped before they took off on them. I can't see a team taking the chance knowing how slippery that stuff is to have the rider rub it off during warm up laps.

Re: "How to toss ur bike b4 tracktime" or "How not to scrub in your tires"

Certain brands of tires (notably Bridgestone) do in fact have a decent amount of mold release on them once you get the blue wrapping off. This does not apply to Dunlops and Michelins, and I am told not the Pirelli/Metzgers either, but with the Stones, I always take contact cleaner (not Gas, Alcohol, Nitro or anything else) and spray it on a rag and wipe the entire contact surface before putting them on the asphalt. Even with warmers, I have seen several Bridgstone mounted riders dump it in turn 1 even at very conservative speeds.

It has been my experience that weaving does nothing but piss people off.

Just get heat in it. I use brand new tires all the time. Put the warmers on, do a couple easy laps, and you're ready to rock.
