Congratulations on a VERY well made conversion !
My suggestion : next time you want to spend some money on her, consider a chain conversion.
Chain conversions are reasonably cheap and allow you non only to have a much stronger final drive...
... they also allow you to "play" with final drive ratios and go for "long range cruising" ratios / dirt road ratios...
In my case, I replaced the belt drive (2.96:1) with a 17/49 #530 chain drive (2.88:1)
AND
the rear tire from a 140/80x15 to 140/90x15 (a bit taller but much cheaper).
The result is 6 - 8% taller gearing, excellent for long range touring without being too demanding.
BUT if I wanted to go offroad, a 15 tooth front sprocket would boost the final drive ratio from 2.88:1 to 3.27:1,
allowing for much improved hill climbing capability.
As a closing remark, if you want to go for a chain drive conversion, always ensure that both sprockets are odd numbers AND not multiples of each other (i.e. not 15/45)
AND
if at all possible, ensure at least one is a prime number.
This way the life of chain and sprockets improved remarkably
