    Stock Bore Size??

    I am going to sound like a newbie(which I am here, but not in general), but I'm wondering if someone can tell me what the stock bore size is on the Pred 90? I am thinking 52mm but am not for sure. Also can anyone tell me if the 54mm is still allowed in the production classes? I would assume no due to it being over the 90cc requirement, but thought I would ask.
