I've just picked up a CD250U and it runs alright but could do with a little cleanup work and tuning. The engine isn't difficult to work on but it would help to know the actual intended volumes, clearances and so on... I've looked all over the net (web, usenet, etc.) for a manual and haven't found anything apart from one copy in a finished ebay (UK) auction. I'd really appreciate it if anyone has or could point me towards an owners manual and/or workshop manual that actually covers this model. (I have the honda '88 general service manual and a CD250U parts list but they're not that much use by themselves). Thanks, Dan.
