Re: ebay kit vs pistonbikes kit
I don't have any experience with ebay kits or piston bikes kits but another thing to consider (I'm assuming you're a fellow Californian by your location) is shipping. When I was looking for a kit the first place I looked at was ebay but found that most won't ship to or within California. As for vendors most won't ship to or within California either. But if the vendor is in California you might be able to go and pick up one up in person. I got mine off VeniceMotorBikes since they are one of the few that ship within California. I live up north away from most vendors in California and needed one shipped to my home. I haven't had any problems with any component of the kit since I got it.
