Where should I take /send my '78 650B2 rotating assembly to be balanced before a reassembly? I am having trouble finding a shop local or not that would even consider doing it. From what I understand, balancing may not be absolutely necessary, but I would like to get it done for my own piece of mind. I am using oversize pistons and a new used crank with matching rods from a different bike.

are you looking for someone locally? APE racing does crank work I believe.

Im unsure as to how I didn’t find APE’s site when looking but they seem to be the most reputable source for this service so I will be sending my crank out to them.
Thank you for the input.

Balancing shouldn't be necessary and would be quite unusual. My 750 which is almost identical to the 650 is very smooth running.

I guess Falicon is no longer an option.

Do you not think balancing the crank is worth my time? I figured I’d go ahead and get it done since I have the motor apart.

I check weight on all rods & then pistons you should be fine.
