i was in florence oregon a few days back and i was just out on the top of a dune and a blaster drove by but i thought it was 400ex so after i cought up to guy back in the camp ground apparently he modded it so he could put a 02 honda 400ex engine in because the blaster engine blew...he said there was alot of welding involved. he had to modify the engine and carb and everything but thats all i got out of him when i was talking with him..
