secondary spring color

[TJRTX]

Could someone tell me what color secondary spring is on an attack (136" track). I'm trying to match an attacks gears and clutch setup when i stretch my 07 rtx to 136. I know now an attack has 23/38 gearing with a 70 L chain. Some people have said 68L chain would work with 23 top gear, but port yamaha told me otherwise.Stock on my 07 is 22/38.
Thanks.

Attak got the white spring twist at 60*....3-3

23/38.....70 links chain

Thanks Rockrtx. I see you have 23/38 gears on your rtx. How do you like it and what color spring do you run with.
