What is the stock bore size on a TRI-Z?

[Blown 331]

I hate to make a thread like this but I can't seem to find the answer anywhere. My TRI-Z has a 1mm over piston and the new pistons don't seem to list the amount over sized just the overall size. I need to know the stock bore size so I can add 1mm to it to find out what piston I have. I'm at work and don't have the piston with me now or I'd just try to measure and I need the answer asap. Thanks.

Damn, Thanks. I don't know how I missed those. I didnt' know about the specs page but I don't know how I missed that thread on a search. Looks like stock is 68mm so that puts me at 69mm. That sucks cause here is a new Wiseco 68.5mm on ebay for $14 with 3 hours to go.
