Adjusting the air screw like above will tell you what pilot to use.  Does morse have the cr ignition advanced a bunch?  That would add low end.

I go by if the air screw is 3 turns out go the next pilot size smaller
so  it looks like you are still rich on the pilot after you get the pilot working with the air screw 1-1/2 turns out adjusted properly. Then put a bigger main jet in it then go after adjusting the needle

Dont go riding the bike WOT until you get a bigger main in it.

Anyone looking for a great builder I highly recommend the following.
For CP products dealers I would recommend:
Arlan at LED(site sponsor), Pete Schemberger at Hybrid Engineering, Mat Shearer at Shearer Custom Pipes, Dennis Packard at Packard Racing, and Nate McCoy of McCoys Peformance.

Other great builders I also would recommend: Neil Prichard, Jerry Hall, Bubba Ramsey and James Dodge.

I know Johann's runs good, I have ridden it. But, a drag port is, a drag port. Ask troy how much bottom end he had with 496cc's!

My timing is stock position.  I know motor to motor you can't compare no two are the same. But mine has a very strong bottom end so much so it's hard to hold down low it likes to wheelie I'd say it has the grunt of mx style porting
