For you folks in the know, Is there a correlation between raising your exhaust port timing and having to use larger main jetting? Thanks

No and you shouldn't be raising the exhaust port you should be lowering it.

always appreciate your info.

No problems

Raise your exhaust port/increase your exhaust port timing (duration)?
