If you do convert one dont forget to do the suspension as well as the wheels and brakes, ive ridden a few Moto's where they havent bothered and Handling was bloody scary I would definetly recommend taking a look at the DRZ400SM if you can, its a smaller engine than most but its a really solid engine and will go forever, plus you can get one brand new from Suzuki with all the trick parts and a full warranty to boot [thumbup]
