Thoughts on this combo for E85

What ICON pistons model do you have? If you go for the dished ones versus the flat tops, the bobweight for balancing will go down, and so all that will have to be done is to remove some material from the crank counter weights. It is easy to figure up the new bobweights, and you take that and just the crank to a COMPETENT shop. Ours was in for a bit over a week..... all of $95 to balance the crank to the bobweight number that we figured up and gave them. Eagle has a balance card example on their site and all you have to do is follow the formula for bobweight. It ain't rocket science. ("All you gotta do"... ain't those great words? LOL)

The KB pistons and pins come pretty well weight matched and close to spec, and it is easy to check at home or work on a gram scale. Ditto for new Eagle rods.

Edit to add: Or you can just buy a different set of wrist pins and end up at the same bobweight and not fool with the re-balance. I think I see some on Ross wrist pins on Summit right now that will just about compensate the piston weight change.
