After reading through the "performance jackshaft" sticky - I decided to give one a go. The craftsmanship and ease of install looks awesome on the PMR unit - but that takes all of the fun of fabrication out of it...
I decided to pick up an Azusa jackshaft kit and make up some plates to install. It worked out pretty well - I cant believe the difference in performance! Perfect addition to a DB that I picked up for my 7 year old son.
Now to get some paint on it before it starts to rust (took a test drive out in the snow!)
