My Go 4 project… got er running really smooth, got a thumpin sterio installed by Unique Auido, under glo, and a new paint job. Put a cold air intake with a K&N cone filter because in hot weather these things just suffocate. Eric, a good friend of mine did an amazing job on the paint…made all the difference in the world. I get offers every day to buy it, but I doubt i will ever be able to part with it. I have done 60mph…once…but it cruises at 45 around town comfortably.
