...

We like to make as much horsepower as possible in our 250F project bikes. After all, the smaller bikes are fun, but at times you can find yourself wishing you had a few more ponies working for you. Enter the big-bore kit.

The problem with trying to push the limits on horsepower in a highly modified engine is that it tends to make it more fragile and much more expensive to build and maintain. One way we can accomplish our goal of more power without breaking the bank or blowing up our new steed is by dropping in a big-bore kit.
