Lighten up a little herp. It's a stickied thread for a reason, only commenented that she learned something. Who died and left you in charge??

Amen to that, I feel like he's been the old post/thread Nazi lately ! " This thread is 2 years old, Don't post your problems in other people's threads, There's no need to post in this thread " Dude needs to relax and quit jumping on everyone with that petty stuff !

I know of no rule that says you can't post in an old thread. The only rule I see being broke is NON moderators trying to moderate other members posts. I don't see what the big deal is .

Can I get another amen ! Good point bro.

I'm just glad that this place is not like some misfit forum where the newest thread takes over a full week to get a new post in it.

I see your list ends at 72.50 is that the max. you can go? Is the liner getting to thin? Wossner forged pistons are available for dt200 which should fit blaster, 73.94 is their max. piston size
