Replace it with a 6.5 hp engine...then it will be a bad bike. Other wise remove the governer but dont push it too hard
45mph
a mini bike with a 90 pound person on it that is 97cc can go 50mph
Monster Scooter Parts has several tires available for the 97cc Baja Doodle Bug: http://www.monsterscooterparts.com/badbscpa.html
A 2.8 = 97cc
with 24 mm
42 mph
5.92 cubic inches is 97cc or 97mL
You put 0.8 liters of oil
Probably around 30 miles n hour (50km/h)
get a nitrous kit off ebay....probily 20-35$ or ther is also a way to bypass one of the trotle spring to allow higher rpm's you can use a a pice of wire or somthing of that nature. do this by replacing the small spring with this wire.
my kids is way to fast it will do about 42 mph which is way to fast. It needs to be slowed down so it will have more low end power.
