Reading thru this just piques my curiosity.
In another thread recently a question was asked about installing and running a centrifugal
clutch. One respondant mentioned the additional weight served as a heavier flywheel and
tended to smooth out the vibrations. I've looked at the centrifiguls and there are several
setups but the one that catches my eye (if I understand it) allows for recoil starting and or bump
starting.
Would doing this and tuning the HT to deliver more torque at a lower rpm and using a numerically
lower sprocket....say a 36T
give adequate power and speed to the satisfaction of most of
us ? I mean staying within the speed limits of our state and still getting the 150 MPG+.
I'm still convinced that the basic kit with some out of the box tricks on the carb/petcock, replacing the threaded fastenings with stronger ones, and the addition of a expansion chamber & silencer
would be the best bang for bucks one could want. (while staying within the law)
There are just a lot of problems associated with going for HP at high RPM. Espeially with a simple,
if not primitive, little motors like one of these HT's.

I installed an upgrade air filter and put an O-ring in the manifold a couple weeks ago, was really pleased because it allowed me to break the 30mph barrier, went from a top speed of 29 to 32, on my cheap digital speedometer fwiw. Really ran great for about 5 miles then it started surging and getting slower, and slower, and slower. I was about a mile from home and I noticed the engine visibly vibrating, sure enough both motor mounts were loose. Tightened them and instantly the engine ran great again. As a side note, I probably do 90% of my riding on gravel roads and I was suprised to see how little air filter the stock engine kits have.
