teeth count increase limit??
Please forgive the late reply..
I have been riding a few trails on my '91 TW that came with stock sprocket sizes 14/42. The torque feels totally gone when trying to accelerate and push through fluffy Florida sand and uphill terrains.
From reading this forum, is it possible to add a second rear sprocket to have the option 14/48? Or am I limited to only a five tooth increment without removing chain links..?

I can't afford a new chain at the moment, so I can't consider adding and removing chain links when I need to switch the two.
My chain is a little stretched and is on the second to highest strength on the "snail" for the rear axle distance, so a few more teeth definitely shouldn't hurt.
I really need some more torque out of this bike that could also come in handy when merging or catching up with heavy traffic from a U-turn.
I barely go around 60 mph, always around 40-50.
CAN I INCREASE MY SPROCKET TEETH COUNT MORE THAN 5 TEETH? MAYBE 6 OR
MORE? Not interested in chain link removal/add on.
