440 big bore

[b400ex]

I have a 400ex and i need more power. I am considering the 440 big bore kit. I can buy the kit for 150 on ebay with a weisco piston and more. I just need to know how much it will be to actually have it bored out by a mechanic. thanks for the help

well if you take it apart your self. very easy just get a manuel.

the re-sleeving and boring would probably be 60-100$ maybe a little more it depends on the shop.
