372xt

I have a 372xt that I would like to get ported. Who will work on used saws? I'm looking for porting that will leave the strato ports moving air. Thanks

So I've heard of guys doing this and know it can be done and all that, but is it just as simple as removing the piston and cylinder from the XT and putting in the P&C from a non XT in there? or do other components need to be switched out also? nextly, do they still manufacture OEM non x-torque...
