Engines, suspension parts, etc. are all interchangeable by years, correct? I mean an engine from an 87 or 89 should bolt into an 88 frame, right? Same for forks and triples, guages, etc. from different years of the F1 model? TIA, SR

 

i have a honda shop manual and it covers all early 600 model years 87-90. everything mechanical is the same. the only major differences was vacuum hose routing and electrical harness and some other electrical parts.
