Any advice for a beginner about to work on a cafe build of a honda cg 125?

I am pretty much clueless and planning to learn as I go. But is there any thing I should keep in mind as i go? Also any experienced advice on where to start would be also appreciated via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/9o4us3/any_advice_for_a_beginner_about_to_work_on_a_cafe/?utm_source=ifttt
