JE Piston

[Max400]

I'm putting in my New JE Piston and it came with 4 wrist pin clips there is only one groove on either side of the wrist pin. Is 2 clips all I use? or I'm I supposed to use all 4?
It said to use 4 of the twist in clip but this are just reg. clips.

Oh yeah I saw another thread that someone was asking which way to put the piston in, Well my JE has an arrow on top. That points towards the exhaust (front of mototr) Right?

Thanks for any Help............:D

Check the groove in the piston. If the section of the groove is rounded then you must use one round wire type clip/lock per side. If the section looks square then you must use the flat spiro-lock type clips. If it is the flat type, it most likely uses two per side. Also the piston pin will have a chamfer on both ends if it is meant for round wire locks, whereas one machined for the flat spiro-locks will be almost square on the ends with only an edge break. They DON'T mix and match.
