Level III OCD
Oahu Needs a Motorsports Park
This is an idea for that park:
The money problem can only be solved by a rich dude. Rich dudes are building dream tracks all over the country. A dream track in paradise is possible and it can make a profit.
Space is a big problem on a small island. Build a small track. 1/8 mile drag strip with road course. Infield pits and kart track. 1/8 mile dirt oval with infield motorcycle course. Short sand drag strip. Separate entrances for street and dirt tracks.
Noise is a big part of racing but is a bigger problem for the people who live near a track, thereby greatly reducing the possible locations for a track on a small island. Strict, self imposed and enforced noise limits. Air boxes and quite exhausts on all vehicles. Keep the race vehicles as quite as cars on the show room floor. Stock dirt bikes will be too loud but aftermarket exhaust makers can solve this problem. Apply this rule to generators too. A nice spin off of low noise is the PA system will cost less and you will be able to hear it.
There are fools who will say that it’s not racing without noise and that they make more noise with their street vehicle now. There are fools who will say that 1/8 mile drags are not real drag racing. There are fools who will say a ¾ mile track is too small and that the straight is not long enough. There are fools who will say all kinds of things about how this track is not good enough. All true, but you don’t have a track now do you? This argument leads to what you have now, no track. These fools did not race when you had a track and they won’t even if they lived in a place with a track. There are fools, don’t count them.
How Your Cartridge Forks Work
This photo shows a compression piston assembly taken apart on the left with the rebound piston assembly on the right. Starting on the bottom left is the compression holder that threads into the bottom of the cartridge body. Going up we see the compression stack, a bunch of shims stacked up in the shape of a Christmas tree. The piston. The washer, collar, spring and cap make up a one way valve. Nut to hold it all together.
On the right the order is reversed because the rebound piston controls oil flowing the other way. The shim stack is different because compression and rebound damping are opposite jobs.
Far right is the cartridge rod that the rebound assembly is attached to.
How does this work? The shims bend under the force of the moving oil. This opens the passages in the piston. How strong or weak the stack of shims are determines how much they allow the passage to open and therefore how much damping you have. The oil that has to be controlled is only the amount being displaced by the rod moving farther into the cartridge. Or the same amount being pulled back into the cartridge when the rod retracts. The cartridge is always full of oil. Your shock is a shorter version of this.
I change the shim stack to give you the damping you need. $460 to rebuild and re-valve your stock cartridge forks. No expensive kit needed.

New World Order
Like many bikes in today’s economy the new Yamaha FZ-09 has some cost saving measures inside it’s forks. All the damping is done in the right fork. They did this by just leaving out the compression and rebound pistons from the left fork. Both forks have springs.
This photo shows the main parts of the cartridge from the right fork. From the left. Comp piston assembly. Cartridge body. Reb piston assy on cartridge rod. Spring. Cap with pre-load and damping adjuster.
This bike will get stronger springs for the rider’s weight. I’ll put all the compression and rebound valving in the right fork and leave the left as is. So 2x the valving in one fork much like how some forks have all the comp in one side and all the reb in the other. Total for a rebuild, re-valve and new springs is $560.
If you want I can add the missing parts to the left fork and divide the valving between the two forks like normal. If you want separate comp and reb adjusters, I can put all the comp in the left fork and all the rebound in the right fork. I’m not sure how much the extra parts will cost.
So, if you’ve been bumming about the cost of a kit to upgrade your new world forks, bum no more, LE is here.
So Can You.
I watched a YouTube video today, it was the story of a guy who had a good career as a baker. One day he saw the Thunderbirds flying and decided he wanted to fly. So he worked to get his private pilots license. Next he joined the Air Force, did well in flight school and was assigned to fly the F-15. He met his wife because of this, she was flying F-15’s too. Next he moved to the F-22, then to the Thunderbirds.
At the end of his video he said something I’ve heard from a lot of people who master difficult stuff, I’ve even said it myself.
If I can do it, so can you.
There is no magic to being a great pilot, motorcycle racer, suspension tuner, teacher, parent. Just deciding you want to do it. Then showing up for the job.
Really, if we can do it, so can you.
Are you an Alien?
Marc Marquez goes so fast that he runs into ground clearance and grip limits. Because of these limits he changes his posture to give himself more clearance and grip for different parts of a corner. This helps him battle with the other 3 Aliens.
You are not going Marquez speed. Hanging off like MM when your knee is just skimming the ground and your foot peg is inches above the ground is worst than pointless. It’s extra work.
You are not going MM speed. You are not riding a MotoGP bike. You are not battling Aliens. You do not look cool in the photo’s trying to drag your elbow. You look uncomfortable. You look slow.
The Aliens and all other fast riders have mastered the basic skills of riding, like remembering to breath, braking & down shifting, counter steering, throttle control, lines, up shifting without flapping your arms like a bird, tucking in, looking where your going, etc, etc. They do this stuff so well that they don’t even think about it anymore. Then they add crazy skills on top of their base.
Can you brake hard to the apex of a turn while downshifting? Can you run all your laps on the same tenth of a second? No? Then work on the fundamentals. When you start going fast you won’t have to look for the track photo guy and pose, you will look good all the time.
Get Paid
Busy
I’ve been at a track working or racing or both, the last four weekends in a row. This past Saturday I was at Buttonwillow with the new asphalt with 5 happy clients. Then I drove to Willow and worked with 12 happy clients.
Christian dropped off these bikes for fork and shock springs and valving. It’s good to be busy!
Be Careful The Lesson You Wish For
My fried Michael Gougis has a Blog running that I like. He posts thoughts about motorcycle road racing the world over and photo’s from events he is at.
http://motorbikeroadracing.blogspot.com/
His latest post is about the AMA Pro weekend at mid-Ohio. This is my response:
The lesson you hope they will take is that more racing is better. The lesson DMG will take from this is that one day events are even better than two day events.
The real lesson is that Mid-Ohio is not a suitable track for motorcycle races.
The surface sucks. The run off is poor to none. We are treated badly by management.
There is room to improve run off. The track surface can be done right. Track management can start treating their customers right. They have done none of this. And by track management I mean the person who owns the track.
Motorcycle people like Mid-Ohio because, like Laguna, it was one of the great events that they saw on TV. That is a fantasy based on an incomplete, edited story. Both tracks suck and treat motorcycle racers bad. Get over your childhood crush. Racing is like marriage.
Divorce the tracks and organizations that don’t love us.
Mike is on the Gas
If you have heard my track day riders meeting rhyme, you know that coasting is bad. When I get a question about ground clearance problems I always include advice about rolling on the throttle in turns. I always worry that people will feel like I’m being mean but it’s better to make sure now than to make a sale and not fix the problem. Here’s Mike’s great answer:
“Wow Ed Sorbo,
I met you at an OMRRA race 20 some odd years ago. You guys were racing a FZR600 with a Hawk GT swingarm.
I rode a beat up 600 hurricane to a win in the novice class. You guys added a couple clicks of rebound to my shock, as it was pogoing a bit thru 9.
Its not the opening throttle thing, I’m sure its way to soft for my fat ass however.
Mike”
How cool is that! Team Hawaii raced at Portland with WERA a few times and like most racers we are always happy to help.
