current pulley is a 3" and the motor is a small (looks pretty cheap too) dial adjusted servo motor. The 3/4 HP consew brushless servo is only 125ish on amazon. Is that a good step? My friend mentioned an EFKA but they are a bit more.

I am currently making a stitch down shoe with a Juki 1541 and it is struggling a bit. The material is 8oz boot sole and a 5oz shoe upper leather (both chrome and veg tan). Total thickness is about 3/16". I have a few questions about what the best solution may be. The machine does a good job once I get going. Can I change the pulleys out to get better low end torque? Is there a better or bigger motor I should go for instead of changing the gear ratio? Is there a better all around machine that is standard with the low end power that I need? Thanks
