The 1985-1989 Honda Elite 150 / 250 service manuals can be downloaded below:
1985 - 1986 Honda Elite 150 (32 megs)http://www.hondaspree.net/other/Elite_C ... _85-86.pdf
1985 - 1988 Honda Elite 250 (28 megs)http://www.hondaspree.net/other/Elite_C ... _85-88.pdf
1989 Honda Elite 250 supplement to 85-88 (7 megs)http://www.hondaspree.net/other/Elite_C ... l_1989.pdf
They are close to 30 megs, so plan on a few hours across a phone modem.
You will probably want to right click on the above link, and choose "Save Target As..." rather than letting your browser open it up as a PDF. Esp. those with modems!
These are 4-stroke manuals, but I still get requests for manuals for these scoots. In case you're completely new to these, the Elite 150 / 250s are 4-stroke and very different mechanically to the other Honda 50 scooters covered here, in that it has valves and an oil-filled crankcase.
