big big waste of money.
just save yourself alotta time and even more money bolting stuff on a banshee.
just get it ported.bigger carbs are a waste of money like screamin said without porting.
timing advance ,a lil more compression wih a head. all that stuff don t really shine till you get her ported.
i have spent over 10,000 dollars nickeling and diming myself doing bolt on mods to a bike, i eventually bit the bullet, bought a spare set of jugs and sent them out, less down time that way.it is inevitable.
