Sure. I looked at them and they can definately be improved but I'd love to get your opinion. My dad bought these back around '97-'98 I think and why he went with the 72cc combustion chambers is beyond me.

Bushing the small end depends on cost and what I can afford to do when I'm ready. I'll have the machine shop install the new the new rod bolt and resize the big ends as well as do the balancing when I'm ready to start assembling it.
Another question, should I do the heat treating with the old bearings still in the rods or remove them? I didn't know if having them in would help with anything.
