Hey guys I was wondering if I can get some advice. Right now my Banshee currently has DMC Pipes, single large K&N filter in a stock airbox and the T.O.R.S. has been removed and the bike was rejetted. Im not trying to turn this bike into a drag machine as I love duning and trail riding but I do want some more power. A local builder suggested he could lighten the flywheel, advance the timing and raise the compression for $265. Is that a good price? Will performing those mods make the bike wheelie up and down everywhere to point where I cannot dune or trail the bike? Any help would be appreciated. Thanks.
