possibly. He's got 11 grand sunk into this thing. MOST people dont sink 11 grand into something like a shifter cart then spew bullshit IMO. Two stroke pwn on the top end. He is probably making somewhere around 70hp or so. I dont see how that wouldnt do 150mph. Probaby has NO low end though. Edit, after seeing the pics, you'd have to be fucking retarded to go even 100mph in that thing. I say line up your bike, for FUN, and see what he can reach.
