what is the rider's weight and are you still using the stock tires? Reason I ask is that it will give the other members on here a little data if doing what you did will do the same for them. There are members here that have body weight 110lbs all the way up to around 220lbs or more, just saying.Got a black one 2 weeks ago and put a Yoshi full system and a -1 front sprocket
Used the gearing commander website which was real helpful
Top speed 62 mph according to my speedo but probably 58 true speed
thank you, this will surely help other members who are thinking of doing the same thing you did.I weigh 180 add 10 for helmet and jkt.Stock tires 30 psi 14t front sprocket. I don't have to downshift to third at the slightest hill or slip the clutch pulling away in 1st on a hill.
Hope this helps
