Advice needed for a sprocket ratio of 16 / 45

[Cipher]

My bike is 47/14 stock and eats front sprocket teeth

Can you get a 420 conversion?

eats front sprockets, yep, each toot on fronts are pulling (rubbing) on/off chain link 3 times to every 1 time for rear, plus pulling the chain into a tighter bend.

Always do the changes with the rear sprockets. Making the front sprocket smaller will eat up the chain and front sprocket quicker from the chain having to tame a smaller wrap around. Putting a larger rear sprocket will give you more oompf at the sacrifice of top end, which you won't need with a passenger out, just riding around.

Yeah I am looking into a sprocket around 48 to try on the rear but can't find one that fits

Lots of abrupt hills around here in the city (9 -12 percent being common) and I can imagine needing more with a passenger on

I’m currently running 17/45 on my 79 gs425. It’s in a nice in between from the stock 16/45. Still has plenty of power off the line. I do a lot of high speed (65-80mph) cruising and definitely helped lower the rpms while still having enough general power.
