I drove a transalp for years around europe and overland to new zealand covering 140000km and the only problem i had was the rear cylinder oil scraper ring breaking twice so the good news is you probably dont need the manual(1987 model so maybe honda fixed that problem). However what i did was borrow the manual microfisch from a freindly dealer and photocopied them at the same time reducing the size,and double sided, to save weight. this involves, of course, a special copier which i had access to. perhaps the library ?
hope this helps
