Well I plan on painting my bike but need advice on removal of stickers there the original ones but the have clear coat I know its simple just to sand it but and tricks that will make it easier?

 

Pretty much just start sanding if there's clear over them. you could also try to use an eraser wheel on an air dremmel if you have access. That makes it damn easy to remove any type of stickers (this is mostly used when you're trying not to damage the paint). There's also an adhesive remover that you could try.
