Hey guys trying to get some things figured out for my Blaster. I'm gonna end up getting it bored to 66.5 cause it needs it and maybe some port and/or head work if I can afford it. My question is what size sprockets should I get, gonna be mostly trail riding, there ain't many places I could even use 6th gear around here. I already got 18" rear tires so I was thinkin like 14/40. Also I'm thinkin bout gettin a new pipe, but not really sure what would be best for my kind of riding. I already have an fmf power core2 silencer. I just don't really know where I'll need the power at. I know trail riding I should keep higher rpms in lower gear when riding so maybe more power in the mid?
