I found an unobtrusive place to remount the tire pressure decal...Yamaha Sticker on the rear fender will be the easiest, Info sticker on swingarm is not to bad either and I and some others have saved that sticker and stuck it on front part of rear fender under seat. It has some useful info on it like tire pressures. That warning sticker on the tank is a real mofo. you will understand when all you finger nails are worn out. HEHE
I would be very cautious about leaving a solvent of any type on a painted surface for any length of time. Sure the sticker may be removed, but would not want to risk the finish of the clear coat / paint.I was told by a Yamaha mechanic that if you place a WD-40 soaked rag on the tank sticker and let it sit for a couple hours it will come right off.
