The first thing I would suggest is to put the stock jets back in.
Why anyone will start to make modifications to a poorly running bike is foreign to me.
Fix the problem and then, if you want - make modifications.
You may have compounded the problem with those non-stock jets.
Of course I am sure you will stick with him to the bitter end in trying to get his bike running properly.
You should since you're altering it before getting it running properly.

Putting in 38's isn't that big a deal and they work well with the gas we have around here. We were in there to change them anyhow. And
we'll get'r right.
Since we tag-teamed this bike, and he worked the left side and I worked the right, I checked his work of the left and found an air filter boot not properly seated on the carburetor. That corrected, the bike is running much better.
I rode his bike this afternoon for the first time and the mid to high end feels fine. However, there's still a bit of popping on deceleration. Tomorrow we'll use starter fluid to check for vacuum leaks. One step at a time.
