Engine Differences

TY175 and TY125 share the same engine/gearbox and from what I understand you can slide a 175 Barrel/head onto a 125,whilst fitting a larger 175 piston/small end also........so I figure conrod is the same........unless somebody knows different.

According to my Haynes book:

stroke 50mm for both

bore 56mm for 125 and 66mm for 175

primary ratio 74/19 for both

transmission ratios the same

final drive 37/17 for 125 and 51/13 for 175

Only lists side clearances for rod, not diameters so I can't see if the sizes are the same.
