I just order the decals off ebay from minibikepaul, super easy to do, and I like that he will sell you just a single instead of a set if needed to.
I love the Briggs sets, and the tecumseh flags and ballons, I have to say I do preffer some of the peel and stick when I have them for the air filter and info decals on the tecs though though, the waterslide ones I think could have been done better (they are kinda digital looking)
Some of those decals peel and stick ones on ebay are total :001_9898: wrong size, really incorrect, stuff like that
waterslides from MBP I used within the last year:
waterslide over OG paint :thumbsup:
