Your crank would need to be inspected before anyone could tell you wether its good or bad. Pipes and porting are the 2 biggest improvements on a Banshee. A "modded" shift star is one that is modded (corners rounded) so that it makes the bike shift easier. T6s are a good pipe for all around increase and trail riding. It would be a good idea to talk to a builder, maybe send them your jugs (to either freshen up, port , or just inspect) true / weld your crank, and get your parts. Also makes it nice if you can get your parts & labor all done at a 1 stop shop to save time and shipping! :thumbsup:
