Anyone install the Wiseco Big Bore 988 or 904 kits in their standard Bonnie? What kind of power gains can be expected. Any idea on the gas mileage afterward?

The 988 kit is actually a big bore and stroker combined. Uses stock rod length by moving wrist pin further up in the piston, but requires stroking the crank 1/4". I plan on doing it to my bike this winter. Will let you know how it goes about March, as our racing season starts then.
Thanks for the reply, I'm thinking about doing this but if the power gains aren't what I'm looking for I'm thinking about simply upgrading to a different bike. I'm not familiar with the term "stroker" what exactly is it?
