if you want to run pump gas then go with 20 or 21 cc domes, get your bolt on mods first, which are the cool head, you have your reeds already, get a $35 ricky stator plate and advace your timing at +4, pipes, I dont think you can go wrong with t-5's unless you are looking for more of a bottom end pipe. You can find some good deals on here, ebay, planetsand, and everything2stroke, for almost all your mods, I would seriously look into buying used instead of retail unless you have lots of cash to spend. After you have all your bolt ons I would spend some cash on suspention, porting and so on. you should be fine with stock carbs with your bolt ons but once you port you will probably want bigger carb which need bigger manifolds, bigger filters, and with that extra power your maybe gonna want a longer swing arm, so that means new chain, different sprokets, lol you are gonna go broke, welcome to the HQ!!!
