Newparts how much for a brand new or a good second hand seat for a typhoon? its gotta have the bit underneath that goes into the latch also a key and barrel set oh and the "plastic latch" thingy. basically the seat barrel goes into it and when you turn the seat lock the plastic thing then hits a metal plate which undoes the latch. (i hope this is enough info) just those three and then im VERY happy unless theres something else wrong with my bike why it wont electric start...
