vespa CRANK BALANCING with INSETs / pk pv ets / FMPguides - Solid PASSion /

all smallframe cranks are NOT BALANCED.
mazzucchelli = technically very good crank BUT as all sf crank basically NOT balanced. with heavy metal inserts we raised the statical balancing rate from only 20% (!!) to 44% which will be way better

costs for it:
it duplicated the price of the crank to aprox 360,- in total (0,- balancing check and putting it in)

so:
1) cheap sf crank are all NOT balanced, its simply NOT possible for this price, no matter what marketing wants you make believe ;)

2) balanced cranks are EXPENSIVE
u have to take 400-500,- into your hand if u want a good smallframe crankshaft

3) better buy a balanced one, checkout fabbrizi cranks, saw them for 380.-


Needed crank checks:
centering
pressfit
straight stumps
conrod strength
balancing, static rate
