Cracked cylinders can be repaired. Send it to US Chrome or Millenium Technologies. It will come back better than new.

The biggest kits that I know of that are bore-only without stroking the crank are 107cc.

If you really want to do a big-bore right for that engine, buy an 85 cylinder, they are a much better starting point for a ported big-bore engine due to the port layout.

A stroker kit is much more effective for that engine than a big-bore. There's not a lot of added performance with the big-bore, but the stroker engines are much faster than stock. A stroked KX100 will outrun stock 125s with ease.

Are you a very commited racer? Or just have a lot of money to burn? Strokers are very pricey.

Here's one example:

Stroker kits are much more effective on 85/100cc two-strokes than big bores because of the short length of the exhaust systems that the frame size dictates. If you really want the most performance out of your KX100, a stroker kit with a big-bore 85 cylinder is the hot ticket. But like I said, they are quite pricey because of all the modifications required, to the crank, the cases, the cylinder, and even the piston itself.

Just google KX 100 stroker kits.
