Piston Wash

what do you think RICH?

 

[Turk]

Very safe. A pencil eraser thickness of wash around the transfers is about perfect.

 

[mrviper700]

ya, its a little rich

you should be good to about 70 below zero!!!, your way,way to fat!!!

 

[Srxspec]

Hey, you've never even seen him, don't call him fat Mrviper! LOL!

I concur with Turk & Mrviper, you've got room to spare on the jetting!

 

[..SNAKEBIT..]

Thats what I thought never really did the wash thing but from what I thought it looked like it was washing off alot of the top

i'm green at this, so what tells you it's too fat-- more metal showing? what's a good wash supposed to look like? thanks

 

[..SNAKEBIT..]

CORRECT me if I am wrong!!!
small washed off spots by transfer ports (Turk said pencil eraser size)
rest of piston colored not clean aluminum

Here is the mag piston from my 01 SRX. It is a lot leaner then my centre & pto & a lot leaner then I like to see. Going up 1 size on this puppy!

 

[..SNAKEBIT..]

NO WASH?
was I correct in what I stated above?
Thanks

 

[Turk]

There is about 1/2 a eraser around the transfers that is hard to see. It is fine for 1000' races ......but not 1001'! Here is a piston from my 98 SRX that I was racing on a -25 day for long pulls!
