    I picked up a 1979 school bus yellow ct70 and its surprisingly original. It was quite a surprise after working on beat up hardtail z50s for the last two years.

    My goal is to get the bike as close to 100% original as possible. I noticed that some of the decals are starting to peel in the corners. What do you recommend i apply to the back of the areas to get them to stick back onto the frame?

    This is a tough one to answer. You need something thin, so it won't telegraph through and be visible; that eliminates 2-sided tape. You also need something transparent that won't "bite into" i.e. chemically dissolve the paint or decal; that pretty means trim and weatherstrip adhesive can't be used. Doesn't leave any truly clean options that I can think of. Glue stick would be clean, easy to apply and remove any excess but, IDK that it would last long. Contact/rubber cement might be okay; it'd remain flexible and the excess should roll-off with fingertips. Beware, it's snot-colored.

    It it definately an odd request. I'd like to salvage the original stickers on it though since quality repops are not up to par.

    My first thoughts all were of glues with hot solvents...clear coat, clear nail polish, seals-all.
    Now I'm thinking maybe, clear water based polyurethane...minwax makes one, or two. Whatever you use, you'll likely only get one chance to get it right.

    Maybe research what is the adhesive that is used for decals, bumper stickers, price tags, and such. See if there is a similar/same product available. Episode of "How it's made"
