Is it 4 stroking?

Sortof I have a Reed valve and a delorto carberater and a banana muffler and the motor has Poo out work done could it be its not getting enough gas?

It could be running lean or running rich, I've never had any experience with running lean

Look up carb tuning

Did you check that the port mapping was same on new/old cylinder?

No. So I need a new piston?

 

[Frankfort MB's]

No he asked if you checked to see if the top end you put on was right

could be now you have too high compression ratio
or you have a head gasket leak.

 

[Frankfort MB's]

I doubt a head gasket because he said it has good low end power, it could be detonating

What spark plug and octane fuel do you use?

If you have increased compression it could be that you need Jaguars cdi
