Bmax piston sizes
 

Hi,

Can anyone help me on the differences between all the pistons?

I have the following:
n°1 black pistons: 2 holes
unmarked (I will call them n°2 for now) black pistons: 2 holes
n°3 black pistons: 3 holes
n°4 black pistons: 3 holes
unmarkes white pistons: 2 holes

The hole diameters are exaclty the same between n°1 and n°2. The same for n°3 and n°4.

No idea what the white pistons are :-)


I would like to have a chart that tells me which pistons have the most and least pack (smallest vs biggest total hole area).

Any help appreciated!

thanks

I wish I could get the value too to complete a piston chart and a "kind of" damping coefficient chart. I asked someone once, most probably Tom Yardy, but he did get the answer.

If someone with some yokomo shock and a calipers can do some measure, that will be veeerry nice and kind to this person

I noticed that the unmarked pistons were n°1 also, the tiny mark was a bit damaged probably by taking the piston off with a knife. So then it's normal that these have the same hole size :-)

But still, 3 and 4 are also identical.

A pity that losi pistons don't fit, their shaft diameter is a bit larger than the yokomo ones.

The n°3 piston holes are identical to losi red pistons. So with the correct drill it is easy to make orange and blue, but not black (smaller holes).

Sorry to hijack this thread.
On champ pack shocks which pistons goes in front?black or white?

black
