Jesus Christ. Don't drive 100 miles to a shop if you dont even know what to get. What if nobody were to respond to this thread? Would you just panic and not buy anything?
From reading this, I can tell that you are not ready for a nice scooter if you don't even have a basic knowledge of the parts in this industry. I hope the shop is closed when you get there.
Sorry for not appropriately contributing to the thread.
Considering TSI is pretty much on the edge of Business existence and you represent Vertx as a Flow rider I don't understand your hostility to a new rider.
His money can be spent on quality parts that you as an experienced rider could
suggest to him or he can go and spend his money on Chinese import crap and folks like TSI can sell 199 scooters next year rather than the 200 they only sold last year.
