I finally got street legal a few months ago and have been driving it around quite a bit lately. Once I got the feel of how it responds, driving around became really amazing. I have more to do, electric brakes, electric power steering, the second battery box, etc... but its definitely an around towner already.
I did have one nagging issue that really had been around for many years (before the conversion), its just that the vacuum pump made it worse. Before the conversion, I would get squeaking going down the road, almost like a rubber on metal sound. I chased it for a bit but I couldn't reproduce so I gave it up and lived with it. Now with the vacuum pump and its squeak, I would get it constantly when the pump ran. I spend 5 minutes today tracking it down in the driveway with the hood up but couldn't reproduce. I closed the hood but left it unlatched so I could open it quickly if I heard it. No squeak. Finally when I latched it and made the pump run, success. Long story short, for 8 years I lived with a squeak that I was sure was body mount of shock bushings. Turns out it was just the springs in the hood latch. A little WD-40 and all gone! I'll need some better lube but so satisfying that I found it.
So if your chasing a squeak, check your hood latches first. I took one off but then realized I could spray lube in through a small hole just under the hook part.
