TZ Heads

TZ Heads

I had 2 used and 1 damaged head for my ‘90 TZ 250 that you may recall I’m restoring while Tony races it. If you don’t recall just scroll back and check out the posts about this project.

I sent the heads off to Roland Cushway to be re-cut and could not resists posting this photo of them. I wish I had before photo’s. Roland and I think alike, we like to sleep in and work late, we like our stuff to be clean and we are not afraid to share knowledge.

If you have talked to me you were probably surprised by how much information I give out in my answers to your questions. Most people want to keep info to themselves thinking that knowledge will give them power of some sort. This is true but only in the sense of slicing the pie into smaller pieces, Roland and I want to bake a larger cake. I find that when I give you knowledge you become a better client better able to maximize the changes I make to your suspension. With a better understanding of what your suspension is doing you ride better and make my work look even better. Call it a “multiplier effect.” I find that you are less likely to take my knowledge, start a suspension business to put me out of business and more likely to be happy with my work, send me more work from your other bikes and tell your friends about me.

Anyway, these heads will soon leave for England along with the rest of the parts and the TZ to live with Russell, it’s new owner.

Happy Rhyme

You may have heard my rhyme in the riders meeting. This just in by e-mail from Tim, a friend of Dave.
 
What his prose lacks
in metre, and rhyme
won’t matter one bit
when you post faster times.

For a mere fifty dollars
a pittance I say
he’ll tweak your suspension
and help you all day.

He’ll twist all the clickers
and set the pre-load
adjust the rear shock
in crew chief mode.

He’ll advise, and coach you
that’s his bag
come back for debriefing
he’ll adjust the sag.

He’ll take out the wobble,
the chatter, and dip
the jinx, the jive
and all of the skip.

He moves with purpose
he’s fast as can be
Oh, and remember
the sarcasm’s free.

Ed, thanks for the help at Willow this last weekend. Whatever you did to Dave’s r6 worked. I checked it when we got back home, and it now registers 100% throttle. Who knows, all this hype about you being an F-ing genius may actually be true.
Thanks again, Tim

No Tim, Thank You!

CB750

CB750

Yesterday a CB750 was thundering around Willow Springs. It’s owner rode well and did a great job maintaining his bike. I liked the way he upgraded it without going too far. For example; he had better calipers on the stock rotors, he did not put a GSXR front end on it.

I have to apologize, I don’t have a picture of the whole bike. I do have two shots of the neat shift link he made for GP shift.

Turn One

Turn One

This is me on my ‘93 TZ250 in Turn 1, Short Course, Hawaii Raceway Park in about ‘95. Eric (CBR900RR) and Kim (TZ250) are on the up hill part of the track and I’m on the down hill part. We are turning off the drag strip and the center line I just crossed marks the top of the camber that lets the water drain. The drag strip was 4 lanes wide, two on each side, the dashed line between Eric & Kim is between the 2 lanes on the right side. I’m about to cross into the 4th lane. The apex of T-1 is to the right about 10 yards out of the shot.

I’m posting this for two reasons. One is that it’s a great shot that makes me look good. Two is that it shows hard braking in a turn. You can see my fingers still on the brake lever and by the forks that I’m not at max braking any longer.

On a TZ max braking is limited by keeping the rear wheel on the ground. So I would squeeze the lever till I was at max braking while going straight right next to the white Armco and keep it there till just before the crest then start easing off the brake as I roll on the throttle.

My knee would be on the ground by the dashed line between Eric & Kim still with the brakes on just as hard as they were in a straight line. I’m telling you this to give you an idea just how much traction you have at turn in if you keep the brakes on. Letting go of the brakes then turning feels like you have no grip because you are coasting and because the suspension is not loaded you don’t have any grip.

You have to work up to this. Start by easing off the brakes as you turn in. Once you are good at that, ease off less and less. You can’t brake as hard on a street bike with DOT tires as this but you can keep you suspension stabilized and therefore give yourself more traction. Also work on rolling on the throttle as soon as you let off the brakes, again so you are not coasting. Coasting is bad.

As a free bonus your bike will turn in easy because you compressed the front end 4 or 5 inches. So if you lowered your front end for easy turn in, it’s time to put the forks back where they were because the few millimeters you moved them is nothing compared to what you can do with the brakes. Worse, you made your bike unstable when you tried to make it easy to turn.

It’s not the bikes job to turn easy. It’s your job to flick it. See the guy keeping up with me on the CBR900RR that he rode to the track every month? The skinny guy in front of the other TZ. The guy with the same DOT tires he used on the street riding that bike to work everyday. How come his bike flicks? Talent. Skill. Knowledge. His bike is stable freeing him up to use his skills to ride faster. And he is so good on the brakes that we called him, Madman. You can see that Eric is still on the brakes and I assure you that Kim is too.

Also note that we are all looking thought the turn, all have are head and eyes level. None of us is holding our breath and even thought this photo does not show it none of us were dangling our foot.

A good day at the track.

It’s been about 6 months since I’ve had a chance to ride so I was happy to have enough clients yesterday (6) at Streets backwards with MotoYard to have a good day but not so many that I had no time to ride.

I think I rode 4 times in the late afternoon. I went out in A, B & C so I could ride will all my clients, watch their lines and how their bikes are handling, show them some lines, etc.

I’m older, fatter, and out of shape but it turns out I still mostly have it. I gave up on getting all the way tucked and that made all the difference. I can’t see where I’m going in full under the paint tuck anymore but if I look over the screen my head is more level and I can see.

My bike is a ‘88 CBR600F-1 with F-2 front end & Hawk swing arm. RC-30 rear hub, light wheels, Ti pipe, big rad, 76 HP, heavy. And for you kids who don’t know what I’m talking about, it’s so old it has carburetors.

But it has a long wheel base and I can’t crash it. So I brake crazy late and have a blast. Take off slicks and no need to mess around with warmers because I still remember how to take a warm up lap.

Maybe I’ll have time this week to improve the suspension using all the stuff I learned from Jim Lindemann because MotoYard will be back at Streets this Sunday.

If you’re there and get a chance to follow or watch me you will learn something. I started racing in ‘83 and have crashed a lot more than you have. Watch my line and speed in the last few turns before the skid pad…

Straight talk

Wes asked how fast I could replace his fork seals if he over-nighted them to me.  I told him to just have a shop near him do the job and save the $200 or so in shipping.  It’s a simple job that any good shop can do.  I’m happy to do fork seal jobs but spending a lot on shipping just makes it cost too much.  Send me your stuff when you are ready for valving.  This is what Wes had to say about that:
 
Honesty and straight talk reigns supreme! Your reputation is well deserved…
Thanks, Wes
NJ James & his R-6

NJ James & his R-6

I love the R-6. It has a high speed comp adjusters on the forks and shock that I can make work the way it should. This is James from New Jersey, riding my set on his ’11 R-6. James said he went faster an his tires lasted longer.

Track Day set up for you.

Lindemann Engineering!

My name is Ed Sorbo and I’m your Suspension Guy!

Do you want to know why?

For $50 your bike will not wobble, your bike will not skip, your bike will not chatter, your bike will not dip, your bike will not jive, nor will it jinx.

You get that $50 back when you send me shop work and that’s no jive.

Sag and clickers all day long,

Just as long as you don’t cost because that would be wrong.

On the gas, Or on the brakes, Look through the turn, and remember to breathe.

Debrief with me,

Now that’s the key.

I’m set up right here,

And hey! Lets be careful out there.
