Ok. Well here my situation. I have two guys both wanting to trade for my dirtbike this weekend. One has a 2001 660 raptor with a 728cc big bore kit. Full aftermarket exhaust and has been jetted. The other one has a 2002 blaster. Bored .40 over. With full alien dmc exhaust. I'm having trouble on which one I should get. I'm. A little worried about the 2001 tranny on raptors. And the big bore kit may reduce reliability?. And I want to go somewhat fast. Wuld this 2006 blaster fulfill my need?. Basically just want 2 beat my buddies 400ex. Thts now a 403 bcuz it blew up. Id like to keep up with. So if any1 has opinions or can help me out. Thanks a lot.
