damn dude, I couldnt imagine mine with a big bore kit in it. I was going to do the same thing, but the mechanic said the big bore kit would be hard on the rods and you would severely shorten the life of the motor. He told me all I need is the complete muzzy system, jet ket, sprocket and timing advancer and thats all I would need. There's a guy who's got a 99 that has all that done here and has dyno'd 149 at the rear wheel. Geez with that big bore kit you have to be pushing 165 or 170.
