48pitch to 32pitch gear conversion; mm heating issues

16/90 is a 5.625:1 ratio.
13/58 is a 4.46:1 ratio.

Makes sense things are getting hotter since you lowered the ratio (by a substantial amount no less). To get the same ratio with a 58T spur, you'd need a 10T pinion.

Brian I think you meant 10T - Going from 13/58 to 13/58 isn't going to do much... ;)
