I'm trying to weigh my options here...
Not a moped, but it's close enough i think.
I have a Cimatti 86 with a 4 speed minarelli p6 that needs either a new crank, or a new rod. While there is no in and out play of the rod (at least what i can detect) it moves side to side more than i am comfortable with, and with the new cylinder kit it will be getting i'd like to do something about it. The cranks are difficult to find for the 4 speed variant of P6, and the ones that are out there ring up to almost $200 with shipping from Europe.
I can get a rod for about $100, but i'm unsure what it would cost to have it pressed in.
The big question is, can i get away with just replacing the bottom end bearing of the crank, keeping the rod? The bearings are cheap, and it would save me a whole lot of money. I'm just unsure of what typically wears, the rod or the bearing, or both....
This will not be a race bike or a daily rider, rather a fun toy to take on rides occasionally.
Here are the specs of the rod, in case you may know of a compatible one from another bike that would be cheaper:
85mm center to center, small end is 14mm wide, takes a 12x15x15 needle bearing.
Big end takes a 16mm ID needle bearing and pin, same width as the top i think.
