New 4stroke Build.

I recently demotored a Schwinn trike I built for my wife. Thought she might enjoy it. Should have known better. Was looking on youtube at bike camper vids when I saw this Briggs bike. I got inspired and had a 24” collecting dust. I like 24s. So came up with this. Finished it yesterday, and have been shaking it down since. Its stretched 10” and sized to fit a Briggs at some point. Its now running on a 142F.

I have a bike trailer I need to dust off and use, so this is built around trailer pulling. Looks mean nothing on this build, but I kinda like it.
So far it works great, shifts well and cruises nicely. Very pleased with the first impressions. The little 142 is well up to the task. Have more to do to it.

So this build is finished from a construction stand point. Dismantling and painting is next. It will be fendered and red.
I have a lot of red left from the Faux Cushman build. As odd as it is I believe its going to look pretty nice finished.

Awhile back I bought a sheet of G10 fiberglass in 3/8 thickness. I remade the motor mount in it replacing the temporary
wood mount. Its pretty cool stuff, very rigid and tough. The actual mount is the lower sheet in the pic. The black material is a piece of horse stall mat as a vibe damper. The upper sheet is an engine bearing plate. Only the bottom sheet is attached to the frame. Kills 99% of all vibes.

This build works way better than I ever imagined. The drive set up works perfectly after going thru two ratio changes(lower). Its surprisingly quick! I believe would give a stock 66cc a good race.
Was an easy, simple, and enjoyable build. Has about 125 reliable miles ion it now. I ride it almost exclusively
leaving the 2strokes grazing in the garage.

It looks like it would be a fun ride.
How's the shifting? Is it smooth?
Yeah its a smooth shifter. It takes a bit to get used to the concept. The derailleur must be turning to shift. I shift generally at reduced throttle and it sounds very similar to a M/C. You can shift with power and its a quick speed shift,
seems a bit harsh on the system, but fun. Down shifting is easy when not in a hurry by just matching road to engine speed while still under a bit of power. For close stop and go like stop sign to stop sign, I shift down by quickly reviving and and down shifting all gears at once while coasting. Forget to do this and its a problem. I think its the interacting with it that makes this build interesting.

So heres the finished build. I put about 150mi on it shaking it down. It has been amazingly reliable, with the only real changes coming in ratio changes and motor mount materials. Im very pleased with how it rides/functions. The close ups show the drive system and how I used a 160mm brake disc for a spoke protector as the plastic one gave up.

Really like the shifter aspect. Am turning over details of a build to convert one of my Minarellis next

All of your bike stuff is always so neat and clean.
Outstanding job on this bike.
The attention to detail shows.
I bet it’s a kick to ride.
I do like the idea of the shifting to keep the engine in the right rpm range for torque and power.
No lugging or over revving.

If you're a large person with a small engine in steep hill country, multiple gears are a must.

Thanks for the kind comments!

2speed, I assume you are referring to the gear box. Its stock save for removing the inner seals of the bearings, filling the cases with 00 grease and sealing the cases together. Originally It had a gasket and must have been filled with oil as there is a fill and a drain plug. There are seals on the shafts. The 00 is a runny grease travels around with the gears, and circulates with the bearings. These are, at least this brand, well built little gear boxes. I would think run just about forever. Its a compact (except for depth) way to get a 5:1 reduction, much better than the chain boxes. Its quiet too.
