just put on a unothodox pully on my gsr but on the pully there is only one mark and i think its the red mark. so can someone here tell me if i am wright. and if so how do you retard the timming with that pully because i need too retard mine due too zex set up and need too know what that mark is red or the white one

 

So do you have one mark or two??? on a stock crank pulley the white mark is the TDC and the red is 16 degress BTDC..... If you have a timing gun that has digital advance and retard it's really easy to set your timing... Just shoot it off the TDC mark.... I'm not positive but I would think that if it only has one mark that it would be the TDC... Latez

 

Just asked a friend who has one. He says the mark is TDC.

 

Yea that's what i figured... It would be more important to have that then the 16 degrees BTDC tick... Latez
