I've rebuilt motors but wouldn't consider myself a real engine builder. I think it's kinda like balancing a motor after adding high comp pistons, it's a good idea, but most people don't do it. However, brand new Carrillo rods will come with new bolts for you.
Connecting rod bolts are the highest stressed fastener in your motor.
The penalty for a broken rod bolt is generally severe.
IMO, it's cheap insurance, like changing belts at 12k/2yo.
ARP makes heaps of fasteners.
I downloaded their catalog, and they don't have any bike applications that I saw.
I'd say chances are good that they have a bolt that will work, you'll have to chat with them on the phone I suspect.
On the subject of new ARP cylinder studs for '94M900... Has anyone 'pre-stressed'
those five times as per ARP's instructions before final pre-load ? If so what lube if any ?
what torque for each of the five steps ? and what final pre-load torque ?
