Not looking to push a pedal bike and overweight older gent at 45mph on bumpy roads with poor brakes using a ball numbing vibrator for power. Yes. I am different. Have quenched my speed desires in my younger years. Not this quest. Not looking for highest rpm. I live in a resort area with about 6 resort communities (golf carts and bicycles). Looking to see if I can generate interest in motorized bikes as transport/fun option. Maybe rentals. Looking for setup to be user friendly, smooth, vibration free (lmao), reasonably reliable. 25mph range. Able to climb moderate hills. Various pilots. Lower end of price scale, not bottom. Looking at the Jake’s Perfect Bike with their engine kit. Comes with clam shell sprocket. Thinking 46 tooth. http://shop.jakebike.com/Absolutely-Badass-DIY-Jakebike-Kit-333.htm Don’t like the peanut gas tanks, but liking this tank http://shop.jakebike.com/Rear-Rack-Gas-Tank-63.htm I have been lurking around a bit and like: Longer rubber hose intake. Low and mid torque. No foamy fuel. Reed kit, again low and mid range torque Gut muffler and add three 1/4” holes (Gubba) Drill 0.040” hole, engine side above float. Notch slide (Egor) Lighten the wrist pin, drilling to 7.5mm hole on lathe Clean up ports and transfers Bottom of intake, top of exhaust ports Balance the wheels Add front and back brakes Maybe smoother tires Are there other things to help reduce vibrations? Am I missing anything? Love the forum and the info shared. Loads of help.
