dont squeeze the crap out of them, just compress them until the coils touch each other, and release. I think if you do that then readjust your ride height, you'll be good to go... let us know how it goes...

I got this question in a PM, but I thought it was good for the forum, so I'm posting it here. Here you go:

"Hi,

Been trying to get a better feel of shocks setup.Hope u can give me some tips on this.

With a similiar damping,what is the difference between using a smaller piston with lighter oil vs bigger piston hole with heavier oil?

what/when is the application? etc smooth,bumpy...

Do u setup the shocks primary for jumps,bumpiness or grip level? chassis bottoming out?...

I know its a long n tough subject to explained,..hope u can just give me some basic pointers.

Thanks!"

The major difference using lighter oil and smaller holes vs. heavy oil and larger holes is the high speed damping. The thinner fluid is flowing through the small holes at a much higher velocity, and there is much more turbulence, which in turn creates what is referred to as "pack." On the table the two set-ups will feel the same, but the set-up with thinner oil will pack up more when the pistons are moving at high speeds. The thicker fluid inherently flows more gracefully and with less turbulence to begin with, and then with the larger holes, it won't have as much high speed damping, or "pack" as the thinner fluid set-up.

The other difference is the performance of the shocks at varied temperatures. If you use a low pack set-up with heavy oil, you need to keep an eye on your choice of oils. Heavy oil is influenced a lot by temperature variations, much more than light oil.

Another concern is being in the optimum range with your oils. You could go so light on the oil that you are completely outside the realistic range of the oil, just in order to change the oil weights to get the kind of damping you need. You might find yourself mixing oils to get the right damping feel.

Regarding the general set-up questions you had, you want less damping and less pack for rough, bumpy, or loamy tracks, and for smooth high grip tracks you want more damping and more pack. Same thing for large jumps. That is a basic rule of thumb we use, firm suspension for smooth high bite surface, and softer for loamy rough surfaces. If it's really high grip and smooth, you might even stiffen the springs a bit.

Hope that helps... PK

So pittop how do you go about setting up for a smooth track with big jumps?

By the way I pulled my shocks off, and springs, compressed springs, checked shocks to see if they still had rebound, slightly less but still had quite a bit, put them back on and the ride height was back on the money. So I am thinking in a main after various large jumps and bumps for several minutes the shocks start to give some, because they are being worked for so long, then when you finally let them rest they go back to normal. The reason I say this is because in 5 minute qualifiers I have no issues, but in 15min or 30 min mains the my car starts to bottom out while half way thru and lose handling. 2nd time it has happened which is the reason I guess people started putting a sponge behind the shock bladder.

For a smooth track with big jumps I would definitely stiffen the oil, smaller piston holes, and maybe even the springs if the jumps were huge.

Is it warm where you are? Is the car going from a cool environment to a warm one? Make sure the car sits in the sun or at operating temperature before your race. The condition you are describing reminds me of a car that is cold and gets hot half way through the race (in which case you should have thicker oil prolly).

Right on the money, Main started about 3 hrs after the last qualifier and it was cold as hell lol.

I'm currently running CRF US Ed, do you if the venturi fit the new CRF Alpha engines. I'm going to have one of the 5port, do you know what size venturi comes with the engines as it doesnt really say great deal on this.
What size's have you tried using, I'm thinking of getting the 5.5 & 6 but this depends what actually comes with the engine in the first place.

Hope you can comfirm this for me please
Anyone???

The engine comes with a 7mm, but Cody's Worlds edition engine will come with 6.5, 7, & 7.5. Any insert for Team Orion Alpha or Truhe edition will fit. There are inserts available on the Horizon or A Main Hobbies site.

We have found anything smaller than 6.5 can take away too much power and cause you to lay on the gas a lot.
