1972 Yamaha 125 Mid-Range

I was riding the Yamaha this weekend and noticed it ran good starting out and near the top end.

But in the middle it pops and splits, cuts out some.

I made a baffle to cut down on the noise a little, you think that's effecting it?

Would the jetting need to be changed b/c of this?

Any ideas?
