RD350 crank pin hollow vs solid

[Pravin]

Hi All ,

I am going to rebuild my crank now ans I got 2 options on crank pin I bought from eBay are the solid crank pins and one I get locally are with hole

My machinist told me we can't use solid pins as they will imbalance the crank .. I don't understand this properly .

What pins you guys use when rebuilding the crank ? Existing pins reused ? Or new pins ? Hollow or solid ?

Cheers,
Pravin
