hey guys,
i have some queries to know the benefits of a performance expansion chamber?
my mates' dad build's race bikes for KTM, and all his bike have them but not really sure if there worth having on a four stroke ?
or are they a big performance gain or just pointless? :confused-smiley-013
so after burning my leg badly for the zillonth time. im pretty keen on getting some exhaust tape for both the 50's
any recommendations for good places to purchase?
