Does anyone know the correct distance from either the piston face or the cylinder wall to mount probes for a Digitron 32k2? I bought one on ebay, but it is without manual. The sled it is going on is an 02 zr800 cce. Thanks in advance for the help.

This is taken from the 02 Service Manual

Measuring from the Piston Skirt out.

3.937 inches (100mm)

Normal Temp 1250F (677C)
Pre-Ignition 1330F (721C)

Cheers

Well, it just so happens that I just mounted a set on my "01" ZR800. The figure is 3.937" (100mm) from the piston skirt. So you won't have to remove the exh. manifold just measure 1.577" (40mm) from the exh. manifold gasket surface down the exh. manifold. Use a 13/64" (.203") drill bit. The probes will clear the APV's. Your EGT temps are as follows: 1250* at WOT. Deto will occure at 1330* at WOT. Good luck.
