Hi guys I'm new to this forum and let me start by saying hello, Hi! Now to my question, I have a TRF 502X and when I look at Lee Martin's setups he says he runs 1.3 & 1.4 pistons my question is how do u know which piston is which? On the W parts tree there just labeled with 3,4,5 can anyone tell me which are which. Thanks in advance!

piston
3= 1.2
4= 1.3
5= 1.4

but use these pistons that fit better

53976 TRF501X Damper Piston (dia. 1.2mmx2)
53977 TRF501X Damper Piston (dia. 1.3mmx2)
53978 TRF501X Damper Piston (dia. 1.4mmx2)

You may also see Lee referring to drilled 1.3 or 1.4, just get a small drill peice set and run the drill bit through, you can do it by hand.

Thanks guys, now I know what pistons are what. I will look into the getting the 501x pistons if they fit better. Thanks for the part numbers as well!
