372 crankshaft

[motosierra]

howdy..can anyone tell me if a 372 crankshaft and a 272 crank are identical? ...if they are then that would probaly mean that the cylinders have the same stroke?...thanks

They are not the same.

They are different,they wont fit one in the other,same for piston and cyl.Almost nothing from 272 fits on 372.

272 is 34mm stroke by 52 mm bore with a out board clutch
372 is 36 mm stroke by 50 mm bore with a in board clutch

for a worksaw the 372 is better in my little mind but for a racesaw the 272 is hard to beat in the 0-81cc class
