Sounds like chain related to me but recent service should of sorted that out, how old are the chain and sprockets ?...if that was me I would give the chain a really good clean, take the front sprocket cover off and degrease , clean the chain guide that sits on top of the swing arm and reassemble and lube, check wheel alignment both on the swing arm marks and a strainht edge...then a test ride...
One, is never going to be enough.....
