Re: need help in getting more top end speed
Usually the problem- reported all the time- seems to be too rich- to much gas to oil-
Does the slightest chocking kill the motor?
Close the petcock down by degrees- you may notice it runs better then-
most everyone here, myself included- usually thinks not getting enough gas at first
close the petcock down all the time, or mix in more oil, probably the better solution- and motor will probably last longer-
I drilled about five holes in the back of my air filter which helped a lot, more air to gas- leaningit down when it really gets flowing
s smaller rear sprocket like the 36 I installed really helps, because the motor has always run better under load, and now cruises faster
Narrower tires are the old bike racer trick- smoother tires roll much better than knobby too.
keep things lightweight- especially rotating weight- wheels, crank, chain- we used to say when racing that an ounce off the wheels was worth two off the frame
a bigger wheel is like putting on a slightly bigger gear- 27" or 700C is about four percentage up from 26" when you multiply it roughly by four to get 100 percent-
so a motor turning the rear sprocket the same rPMs will move the bike 4 percent faster with the larger wheel- 25 mph would then be increased by one mph, to 26 mph,
and greater then as the speed goes up- not as much difference as changing sprockets, but some- and the rolling resistence of a 1'1/4 inch tire is sooo much less than a 2.25" cruiser tire- if you don't mind the risk
