4-stroke gas scooter build

[CI]

Here is the first test run of the revised jackshaft location, with a functional pulley clutch mechanism.
Sorry about the video orientation; my phone does pretty much whatever it wants to do, in spite of my efforts to do otherwise.
The motor is galloping a bit, due to the governor trying to kick in.
I am going to leave the governor functional at this point, since I think it will be beneficial.

The clutch engagement is silent, as is the operation of the jackshaft and belts, so that is a good thing.
The footpedal is doing a gravity return to the neutral position, but I will add a spring to assist.

Next step is to put the front forks/wheel back on, hook up the brake and throttle cables, and go for a test run.
I am not sure exactly how easy it will be to have a clutch pedal, but I think it will be ok.
The pedal will remain down when the scooter is in motion, and so a safety, since if I fall it, it will stop.

Hopefully these changes will resolve the problems I was having.

Test ride tonight to find out if the pulley clutch mechanism works.
Everything went well.
The foot-actuated clutch pedal is easy to use; I was afraid it may be a bit awkward, but it works well.
You can push anywhere on the bar; the pedal on the end of the bar does not have to be pushed; just push anywhere on the bar.
I always get on and off the scooter from the left side, so the pedal is on the right.

The speed is much slower, and that puts the motor rpm into a good range.
The brake seemed to work well.
I can turn as sharp as I want, and nothing drags on the ground, even if I go over a speedbump.
The belts operate almost silently.

There is really not much to go wrong with this arrangement; it is a simple setup.
4 mile test ride tomorrow.

Edit:
4 mile test run this morning went well.
No problems; no hot bearings anywhere; nice quiet operation; speed range is perfect; the pedal clutch felt natural.
Brake works well.
No more ground clearance problems.
I think this design will work.
No battery charging; just gas and go.

Edit02:
Split rim on the wheels, so the tube will be easier to change than one-piece rim designs.
The tires have a lot of tread on them, so I am hoping this will solve the frequent flat tires problem I was having on my electric scooter.
The tires and tubes for this scooter are resonably priced, and readily available.

The lack of suspension is not noticeable at the normal operational speed of this scooter.
No feeling of getting pounded or jarred when riding.
Maximum speed of this scooter is probably about 8 mph, which is more than enough for my needs.

That's great, CI! Looks good, too.

Looks good.    Do you  stand or sit on the tank of your new scooter?

Thanks much to all for the kind thoughts/words.
This has been a hasty build to say the least, but I am pleased with where I have gotten things.

I considered adding a seat above the gas tank, but then it starts to become a mobility scooter, ie: for old people, and there are no "old people" around here, so no seat is needed.
I sit at a computer all day, and so I need to stand up when I get the opportunity.
I ride it standing up, and it is pretty comfortable.
I sometimes lean forward against the handlebars.


The twist throttle was not working well with the governor mechanism, so I have bypassed the governor.
There is a maximum speed stop screw, and I adjusted that so as to not overspeed the motor.
Throttle works much better now, and without delay.


I remembered that I had a salvaged honda small motor that someone tossed into the garbage, and I removed the muffler from it.
I am going to use two mufflers, with some stainless flexible exhaust pipe between them.
The dual mufflers take the edge off of the dB level.
While the motor with its stock muffler is not excessively loud, I would like to knock off about 10 dB to make conversation easier when riding.

If the weather warms up a bit, I will disassemble things, and paint.
