Wow this should breath much much better. That's how I wish the factory would open them. Looks great. Beautiful work! I'm excited to see it run too.

Forgot the intake pic.

Thanks for the kind words fellas..

Well the comp should get a pretty healthy bump...
Curious to see if it will give the 490 a run.?

Hopefully stomp the 241 by a good margin too.

Quick question/clarification if you folks will allow: I think I understand what "freeport" is... Can someone verify for me?

Looking good Sir! Can't wait to see the results.

When you lower the jug by cutting the base too far that the bottom of the piston is visible above the bottom of the exhaust port at TDC

I never understood why the skeeters don't like 2 stroke exhaust. I love it!

Ya but the exhaust from that stuff can be Uber disgusting! And the smell, horrific!

Baby formula costs more than race gas!

I've been putting off having my shoulder scoped so this should put it over the edge.

Looking forward to seeing it run
