Hmmm. That doesn't really look like a bubble. You might still try poking a tiny hole and reapplying Solvaset. Multiple applications of the softener might also work. Last resort, I have heard of modelers who soften the decal with a hair drier then apply more Solvaset, but you would need to be very careful not to damage the decal or the plastic part. It honestly doesn't look bad and probably won't be noticeable when the bike is complete. Worst case, you can do what I do: just use photos that show the other side. :o)
