qwerty125

hey, I'm completely new to motorbikes, and just purchased an '87 DT125R. I was wondering if anyone knew where I could get hold of a copy of the owner's manual (the yamaha site has no earlier than 2000 - i dunno how much changed '87 to 2000 but i'd imagine a fair bit). Also, what about a Haynes manual for it. The Haynes website only has a manual that covers the DT125R from '88 onwards. Again, I dunno for sure but I'm assuming there were significant changes from '87 to '88 (otherwise, why not include the '87 model in the same manual?)? cheers.
