wOw, you're doing a fantastic job on that custard DL thou, makes great reading, well done yourself, dedication alright. Have you thought about changing both front headlamp bulbs to the likes of Osram brighter/whiter bulbs.....?
And whilst your at it, you could order a two tooth more rear sprocket (Renthal) for more oomph, it does make a better improved/difference, trust me, mines been replaced for nearly a year now and wouldn't go back to the standard sprocket...........ever.
Have fun.
