hey there guys. Bruno here.

Well I got the parts from arias in, and I was wanting to get a little input from you all.

I got the pistons in, and they are made from a lighter alloy, however, I do not know what the total weight was on the stock pistons. So my question is this, what is the weight in grams of the stock piston for a 1988 ex500. If the pistons are the same weight, then the only thing I need to do is have them matched. If they are different, then I need to have the crank rebalanced. Right? I am used to working on V engines where anytime you change a piston or rod design, then you change bobweight and need to rebalance, however I am not up on balancing a inline engine.

Any ideas guys. Also I got a new generator/flywheel and would like to know if this would make the crank system need to be rebalanced. Also, anyone know what a ballpark figure would be on rebalancing this system if it needs to be done.

thanks guys, Ill post pictures soon!!!
