Funny name, we’ve seen it on YouTube, looks crazy but who wants to chase cones in a parking lot? Green Eggs and Ham!

Gymkhana started as an equestrian event and has evolved into motorcycle and car challenges featuring all riding skill sets.

https://m-gymkhana.com/ sets up at Auto Club Speedway on Saturdays with https://fastrackriders.info/ so I tried it. Racing can be like playing chess at 100 mph. Gymkhana is much the same, hence it’s great training for everything we do.

The idea is to ride the course as fast as possible. The trick is, you must memorize the course: From the start box, go through yellow gates, right around red cones, left around green cones, if the red or green cone has a yellow top you have to go around at least 270 degrees, stop on the finish box. Time penalties for messing up. Got that?

It’s not as hard as it sounds. First you walk the course, then you practice, then you race, just like road racing. Well not really. In competition you don’t get to ride the race course. Never mind that, you start with a practice course, this is where I’m at.

I got to ride a KTM 390 Duke demo bike, nice ride. I went around and around. Not having a street bike to ride I‘ve become rusty on some of these sharp turn skills, I could feel the rust falling off. This is great practice for body position, head turn, brake and clutch control, everything. It’s a lot like what Lorenzo did and still does working to be precise in every way.

It’s hard at first, too much to remember, not sure how fast to go, feeling awkward. But that’s my point, if it’s easy you won’t learn anything, won’t try harder and get better.

Riding and racing your bike on track is expensive and risky. So we found ways to practice that cost less and risk less. XR100’s on small dirt tracks, scooters in parking lots, visualization exercises to name a few.

Gymkhana offers all this, a serious mental challenge and wicked fun.

Getting more pointers from James Bush of M-Gymkhana.

Here is the thing that made me realize that I need to do more of this. First the base line of this example. On a road race track with similar road race bikes no one smokes me, the fastest riders in the world can catch and pass me but they won’t just blow by me. I’ll keep them in sight long enough to learn a few things. A few years ago I entered a 25 hour dirt bike race in the amateur class with some friends. There was a pro class too. I was slowly catching the guy ahead of me riding into the setting sun, running over a long section of fast woops, we were doing about 40 mpg. I heard a noise as a pro went by doing about 100 mph. I was stunned. Clearly that rider knew stuff that I have not even dreamed of. Inconceivable. I felt the same way trying to keep up on this course with my instructor. Clearly, I have work to do.

Go right around the red cones…

Check out M-Gymkhana at the address above. The couple who put the events on do a great job, nice set up, good instruction and encouragement. You’ll get to hang out with like minded people, ride around in circles all day and improve your skills.

Left around the blue cones…

With Skill, Speed is Unavoidable.

We use to wash Hawaii Raceway Park, not the whole track just the oil spills from the Drag Racers. These are before and after photo’s of the curbs at the exit of T-6 and T-9 at Auto Club Speedway where I ride with Fastrack Riders and race with WERA. I did not want the dirt to be kicked onto the track so I cleaned the curbs.

 

I’m looking forward to three days of riding the Iceman Ninja starting tomorrow.  I’m going to use the curbs!

Charlie and Marney riding their BMW K1300S on Palomar.  Looks like a tricky down hill turn.  You don’t have to see the LE stickers to know they have good valving and the correct spring rates.

Most people over tighten nuts and bolts. Sometimes they really over tighten them. Using a torque wrench would reduce this problem. Practicing with a torque wrench builds muscle memory so you would be more likely to get close to the correct torque when you don’t use a torque wrench. Using a short wrench is another way to reduce the over tighten problem.

But over tight bolts are not all your fault. Mostly, but not all. Bolts get longer when they warm up and shorter when they cool. When your brakes warm up, so do the caliper bolts. The longer the bolt, the more their length can change. Radial mounted calipers have long bolts that are warmed by the hot calipers.

When you change your wheels at the track, you tighten the warm caliper bolts. When these bolts cool they get shorter and tighter.

I warmed one of these bolts up, it’s length increased from 71.34 mm cold to 71.53 mm warm. I installed this warm bolt into it’s caliper and torqued it to 12 foot pounds. After it cooled, I needed 24 ft/lbs of torque to remove it.

You are already aware that hot things expand and cold things contract. Put these tools and this knowledge to good use.

MG takes photo’s too.  He just posted up his stuff from WERA West @ Vegas.  You can buy them here:
