New project or part out?

Nice, I ride a CRF 450 and I bought the Blaster for my girlfriend but I play with it so much I might have to buy her another one : )
 
That's how it happens! I still haven't rode a 450 yet. I hear that they are out of control! I like my KX, but it could be a little faster. I'm 6' 225 lbs so the bike has to work a little bit. It still wheelies in forth, but I like to be afraid of what I'm riding!
 
If you like to be a little bit afraid of what you are riding a 450 mx bike is a good place to start. My only complaint is that it is tiring to ride because of the power and it's not quite as light feeling/flickable as a a 250 2t mx bike (this has more to do with the rotational inertia of the big engine than the extra 10 or so lbs.) The up side to this is that there is ALWAYS enough power. We ride the dunes a lot and the only thing better for that purpose might be a CR500AF.
 
I went and and picked it up last night. I got it to spark within 5 min of being in my garage. They took the ignition out and didn't disconnect the wire. So I got it to fire up. Turns out it had a lot of after market parts and pieces on it. Has a kiehin 35mm pj carb, stock air box mod with PVC, k&n air filter,Vito's 3mm stroker crank, new top end, full fmf exhaust, hear hydro brakes, home port job on cylinder, full skid plates, dg Nerf bars and I plan on keeping the motor, skid plates, and Nerf bars. I am going to give my buddy first crack at what he wants. Then I'll clean everything up and get it in the for sale post.
