Hi Ash,It slackens the head angle a little and raises the front end quite nicely, I always believe that the front end was to low on these it was lower than my bmx with the original forks and bars.
As for the bulge search dome stickers on google but you will have to laminate them in the sticker as they struggle to bend and stick to the curvature of the frame.
Thanks! Have emailed themTry retrodecals
