My 04 laser 50.....has morini engine, 70bbk, race pipe, 85 main jet, 9gr sliders, 1500rpm torque and clutch springs, partial open filter, speed limiter ring removed, rpm limiter cut....I can only go 35-40mph on it(40 on slight down hill) why what else am I missing? Are these not able to get faster? Little bit of bogging when near top speed if throttle 3/4 or more.....I was hoping for a 50-55mph beast out of this....I talked to others who say they did a bbk and removed speed limit ring and can do 50mph, I'm jealous
