Hi. I'm in the middle of purchasing a 2011 fe 570. I won't have it shipped here for another couple weeks. The deal should be finalized this morning. I'm transitioning from many years on a big dual sport to the lighter funner world of dirt bike, so I'm not savvy on sprockets etc. So 42t. I could ask the current owner what the setup is on his bike...it seems pretty stock, very few mods. But worst case is I could purchase a different sprocket for these yeah? $50-$100? If that's the case. I'd love to grab these. I'll pay your asking price, and if you can meet me 1/2 way on shipping, that would be great. I'm in Boulder CO 80301. You could ship to my townhouse or my office, if that makes a difference in $. And I have to make sure that the bike deal goes through this am, so if you can "hold" these for me this morning, I'd appreciate it. I can email later today. And how do you take payment? Thanks. -Patrick
