I'm currently coming to a close on my first season of riding on a Hyosung 250rr. Hate how you will, but I figured I'd be better off starting small and they're cheap here. Anyways, I'm in need of an upgrade and came across a few options. Currently I'm in Korea and the price of buying used is like $50 difference between a 929 and a 600 f4i or rr so I figured I'd just take the plunge.

As these bikes are a bit older, I was wondering if any of you guys could tell me about specific problems I should look out for when buying the bike (aka problem areas with seals, leaks, kinks, bend, etc.).

I've noticed a majority of the bikes here have about 30k miles on the clock, but everyone I've ever talked to has told me Hondas will run till the end of time with proper maintenance.

Any other advice about the adjustments I'll have to make going up 100hp or from a v-twin to a 4 cyl would also be appreciated.
