When I bought my first Harley ( in 1995 !) , the franchised dealer in WA , there was only Frasers , ALL other WA dealers were under their wing.
You could take your new bike away with pipes and air cleaner kits installed , and the carby "Texas-tuned" to suit.
THEN around the early 2000's Frasers in the east were bailed up by the Polizei and/or the Environmental MOFOS and lost a court case with a BIG fine.
After that Frasers all over Australia would not "derestrict" any new bike before delivery. for YEARS and YEARS.
I just then did my own, and all my mate's bikes as well. Commonplace. Mufflers ex-US etc etc.
Frasers would do it for you at your "first service" as a seperate paid job requested by YOU. Got them round a loophole at the time.
Perth HD opened , and immediately you could get yer Vance & Hines torque robbers for the day you rode out the door.
After a coupla years of Frasers losing business hand over fist to Perth HD there was the inevitable reversal of " The Rule".
In Frasers Perth showroom this morning every M8 model option of 2 into 1 exhaust and or air cleaner version in the showroom. Times change !
