The bike runs fine in 1,2,3 but 4, 5, 6th the is NO power. It cuts out, but does not stall. Any ideas?????? I have a longer gears on it I believe I went up 1 tooth on the front.
by moving up a tooth on the front sprocket u are giving yourself more lowend and less top......but u need to drop the rear sprocket a size to make it more equal......u'll still be getting more lowend but it wont completly kill ur topend like it is now
