Trackday Training with Eric Bostrom – Autoclub Speedway

IJune-25-2016-Fastrack Riders - Level 2 - Grid - ACS_7641_Jun2516_by_BR-CaliPhoto a had the best experience at Autoclub Speedway (June 25, 2016).    I had 1-1 training with the one-and-only Eric Bostrom.  I learned a lot of stuff.  Mainly riding position and letting go of fear. I kept going faster and faster.

Interesting to note that he also made pointers regarding the way the SportClassic likes to be ridden.

He called it the “tractor” effect.  I refer to it as Mario Kart. (lol)  shoot style of naviagting through turns.

The bike was performing flawless.

 

I also was fortunate enough to have former racer John Hilton there.  His approach was different but nonetheless, valuable. I had a 2-for-1 that day!

Bostrom said that the SportClassic is a neutral bike, so enter the turn fast, lean it over, maintain speed to keep tires planted deep, and accellerate as you go through.  Seems kinda contradictory but it worked!

Best of all, I had my dad and great freinds there to support me!

Installed new tires

In preparation for a track day on Friday, April 22, I decided to get some new tires for the bike. Pirelli Diablo Rosso Corsa.   They turn in really nice and I’m excited to test the grip.

Racetech fork springs = Happiness

(Jan 28th, 2011)

I finally installed Racetech springs on my 1000S. Racetech recommended that I go with .90kg/mm (stock is .850 kg/mm) and with 10wt fork oil (stock is 7.5). I weigh 170 w/o gear. (Racetech part# FRSP S3827090)

Now I had done some tweeking to my stock forks before installing these Racetech. I had installed 25mm spacers in each fork and used 5wt fork oil.  It made a big difference over stock but I was still not quite at my goal. I have gone to several track days with this setup and it was adequate but there’s room for improvement.

The Racetech springs were slightly shorter than the stock springs by about 20mm. So I re-used the spacers I made with the Racetech springs.

Without adding oil, I re-assembled the forks and put them back on the bike with the wheel so that I can check the sag. I was close to 50mm!

Then, I added the spacers that was supplied with the Racetech kit to add some preload. It stacked up to be about 35mm high for each fork. Re-assembled the fork again, put them on the bike and measured again.

BAM! 30mm sag (bike + rider)

Added the 10wt fork oil (400cc per fork in accordance with OEM specs) and took it out for a spin.

I AM VERY HAPPY. It tracks sooo nicely. Less nose dive and takes the bumps smoothly.

With the zip-tie on the fork to see total travel, I took note that the fork is about 1.5 inches from the bottom travel. So I’m using most of my fork. I was anticipating less travel but it seems like I’m using (almost) the same amount as before. That’s a good thing!

Best $120 bucks spent.

I’m excited to take it to the track and have some fun!

AAA Speedway

Wow. It’s been soooo long since I posted here. I haven’t been riding much except for trackdays and on sunny Fridays to work.

So on Jan 7th, took a Friday off to take a spin around AAA Speedway in Fontana. I definitely improved over the years. I was effortlessly motoring around that day.

I’ve been going to the gym a lot and it has helped me tremendously.  I went solo on this one and met a couple people there.

I’ll be going again on April 22 and June 8, 2011. Can’t wait!

Willow Spring Raceway

That’s Big Willow to you, sir.

Everything moved like clockwork.  Got up, attached the pre-loaded trailer to the truck and off I went to Rosamond.  Skies we perfectly clear and zero wind.  Temperature peaked in the low 80’s which made for perfect track conditions.  I got there before the crowd and tech’d the bike in 2 minutes.  TrackDaz were the hosts.

I watched a couple of YouTube videos of Willow Springs to memorize the track and lines better but what I didn’t anticipate was Turn 6.  Holy cow.  It felt like you were racing down a steep diagonal  – while leaning hard – while short shifting up – at full throttle – all while the outside of the turn looks like an infinity pool!  If you’re not focused, you are going off the track and into an event horizon.

Then there was Turn 8 and Turn 9, collectively called The Sweeper.  You were wondering if it was ever going to end.

We did encounter many delays because people were crashing out a lot. The two ambulances could not keep up with taking people to the hospital. (yikes)  All of the crashes were occurring within the first 1/2 lap of a given session.  This means that the yahoos didn’t allow the tires to warm up, thus crashing out. (tisk tisk)

After Darwin weeded out the hooligans in the morning, we were able to enjoy an uninterrupted track day all the way ’till 5pm.

I was also able to finally track-test my Brembo Goldline front caliper conversion with sintered EBC pads.  They performed beautifully.  Excellent braking.

I’ve got tons of photos from a photographer friend (Ron Sinoy) and from the track’s CaliPhotography.

Willow Springs is very different from many other tracks.  It’s layout facilitates very high speeds where others have many turns and odd corners.

It is definitely deserves the title of the “Fastest Road in the West“.

That  –  was  –  fun.

Brakes Upgrade

I’m currently in winter hibernation mode and ready to work on upgrading my stock Brembo calipers to the Brembo Goldlines. This is a 2 piston to 4 piston axial caliper conversion.  This caliper comes off a Ducati 748/996/998.

The stock master cylinder should work fine and after lots of research, these Brembo Goldlines should bolt right up nicely after I remove 4mm off the mounting bosses so that the caliper lines up with the rotors.  The Alpina rim’s spokes clear the back of the calipers.

Braking will substantially be significantly stronger (not that it wasn’t already) and modulation should be very nice, too.

The inspiration came from riding a KTM 1190 cc RC8-R on the track with radial mounted monobloc 4-piston/4-pad calipers. Dual rotors at 320mm.  Sick braking but too “digital” for me. The goal for these brakes is somewhere in between.

With these calipers, I should be close to the KTM but smoother.  🙂
