The first thing to do is loose the stock exhaust, it must weigh 20lbs and is a piece of junk, put a vance and hines, kirker, etc. on it. Then you rejet the carb a size or two larger because the bikes run very lean from the factory. The carb boot is a failure because the heat and vibration pretty much beat everything up on the bike, it is only a 15$ part though.
If you plan on keeping the bike change the oil and primary fluid every 2500miles, preferably less. Actually you can change the primary at 5000miles but I would do it more. Both are easy to change but some people complain about changing the primary fluid because you have remove the foot bracket. Using univeral joint it is only a 15-20 minute job. Setting the primary tension is kind of weird as you tighten it down then back it off, if you don't do it right you'll hear a whine from the gear box. I tune it by ear now.
Not much else to say other than the blast is a great city bike to ride in Frisco as it is small and light and has plenty of torque. Sure the sv650s will pass you, but for the cost I think the blast is a good bike and you don't see them everyday. They are very low maintanence and are tough little bikes, I'd like to see someone drop a ninja or SV a bunch of times and see what breaks on it.
