sorry guys i could not get an answer in the motorcycle fourm. just bought my first bike, 2000 honda reble 250. love the bike. just wanted to know if there was any way i could punch out the exhaust pipes to make it sound a little meaner? would i have to re jet or do i not even have to worry about it with this bike? also if i bore out the pipes what will it sound like? any info would be great, thanks guys
