even barnones 45 to 30 swap (right?) was/is only a 30% boost to stock

mine has been faster than 60 , since 8 days after it arrived and I maxed front sprocket

yes up an incline or stiff headwind and nothing to draft 60 still my max ,,, in 4TH gear


IMO , you cannot possibly attain that which u have already givin up be4 u started , by gearing so low

if you've geared for 75 even down hill you will never pass that speed as valve float will actually engine brake u preventing more speed EVER from being attainable

gearing really high has drawback being really hard on valve train
