long time lurker, first time poster.(dont look at my forum birthday, ive been following tsm since jan 2010) it seems i have come into a possible yz 490 parts bike, i have a rolling chassis from a 87 yz 250. they seem very similar but im not entirely sure (i was 4 when the 250 was built), and i realize the 490 has a number of problems(which can be fixed through some simple machining). im really feeling the urge to make a dune dragster or possible hill climb project(being from ohio and silver lake dunes in michigan) out of this.
is this swap/interchange possible? i will continue to search part numbers and see which ones match up for possible swaps, but any knowledge or vintage 2 stroke wisdom is greatly appreciated.
EDIT: MORE PICS!
EDIT EDIT: i cant seem to get them to work, so photobucket link is in my next post, its been updated.
