$5700 nice bike, stock, r miles to high?

You should be fine. Have the valves been checked at 6k miles, if not, that should be done first. i have an '08 with 11k miles and it runs very strong. Valves were good at 6k, and regular oil changes.
I have done a lot of mods also and do my own wrenching, and expect a long life our of mine.

Very good price.........if it's in good condition, I'd buy it.....miles mean not so much........valve adjustments are not nearly as frequent as most other enduro's...show us da pics..........:ride:

Ok I'll check on valves adj, but yes very very nice
