Default 98 YZ 250 powervalve

I have questions about powervalve, I have heard and seen, that 98 250's the valve hits the top of the piston. How do you prevent this?
Also I went to the dealer to order a new powervalve, and they said it is a one piece.... Mine was a 2 peice... One piece wouldn't fit... Have anyone had this same problem? They are telling me they can't order a two piece powervalve.... What's up with this.????
Please help... Thanks
