hey all...i was wonderin if anyone has info on sprocket sizes for a 300 ex. im running 20s in the rear and with the exhaust, filter and jet im hitting the rev limiter in 5th on the long straights. i recently went to a 14 front sprocket up one from stock...should i go down one or two on the rear as well...what are you peeps running for sprockets. i want a little more top end but dont want to lose the low end torque too much. any info is great...thanx
