Nobody has objected to my 4 stroke Moped.


Here are my 2 CT200's.

Depending on the clone engine, wiring the headlight to the battery isn't always a great idea if the alternator has a circuit for AC power to the headlight.

This is because the electric start engines tend to have a more powerful alternator to handle keeping the battery topped up, which would be my choice for an engine powering a battery powered headlight.

I've found both of my clone engined bikes,. ( both are not E-start..) keep the battery in a happier state of charge with the headlight on the separate AC lighting circuit. Most honda clone regulators have a voltage regulator ( usually integral with the battery regulator.) on the AC side, for the headlight.

It does mean you have to wire your headlight to constantly on, or chose a separate switch arangement that isolates the lighting AC from the battery's DC current.

Good luck on your build, I wish that these engines had been available back in the '70's when I owned a pristine old CT200, the extra thrust would have made the commute a lot more fun. That being said, those old ironhead OHV 90's were very good engines, and could withstand running for hours with the throttle near pinned.

Change your oil often.

I've been pretty busy lately with other things, but I've managed to find a bit of time for the bike.
I got her running, and I had some issues with the exhaust smoking really bad. After taking the head off and replacing the valve seals, the exhaust smoke was gone. I also replaced the junk clone carb with a genuine mikuni vm26 and she's running better than ever.
I also had an issue with the engine knocking. It turns out the 'centrifugal oil filter' was loose. easy fix

Last week I got my parts from across the globe. Here's a couple of pictures.

The color of the headlight surround is a bit off. Might paint it, might not.


Here you can see the bracket I made for the oil cooler, along with my new carburetor. Praise mikuni!



I just need to wire everything up and work out a few things, and she'll be ready for a plate and an ohrv sticker!

Looking good. Are you going to run a battery?

I know what you mean about being busy!
Wife's brakes...
Daughter's car...
Oil pan seal leaking on my car...
Other bike work...
Plus, the job!

I really need to get back to work on mine before the fall riding season.

I'm thinking I'll wire it up without a battery like I had it on the magnum. If I find my lights aren't bright enough, I can always throw a battery in it later.

Another great CT90 build. I have got to get me one of those. I currently have an '80 Puch Newport II with the original ZA50 2 speed engine. It tops out at 30 mph on level ground, but with the low first gear, it will climb anything while keeping the engine speed up. I have a nearly new E50 single speed motor for it if the ZA50 ever blows up.





But I want something small, with better suspension, that can reach at least 55 mph on a level road, with a manual transmission so I can ride it in the mountains without lugging the engine like on a 125cc CVT scooter.

A Trail 90 with a more powerful Lifan engine makes an excellent trail bike. Small and light enough to go places a larger bike can't go. Enough power to keep up with traffic around town. Easy to haul on a bumper rack on an RV. You can have a day of riding fun on a gallon of gas.

Have you heard about the new Honda Grom? Seems to fit your bill perfectly.

@JerryH

perhaps a road legal motoped would be a good bet

A Grom is a toy. Way too small for someone my size. I fit on my 50cc moped way better than a Grom. I can sit up straight on that. There is no way I can see that a Motoped could ever be made street legal in my state. No VIN. A Trail 90/110 would be about perfect. And there are usually several reasonably priced ones on Craigslist. But I have simply run out of room for bikes. I have 6 running bikes and 2 parts bikes.

Sweet puch Jerry!
Here's a pic of the maxi I built a few years back:


It's got a few engine mods; 70cc kit, race crank, expansion chamber, 19mm carb.


In ct90 news: I'm currently awaiting my new tire to be done it's spin in the dryer before I pop it on.

Got the new front tire mounted! Amazing what a new pair of shoes (or at least one new shoe) makes a bike look so much better. The old tire in the dryer worked wonders. That and some spray on silicone and my trusty tire levers.
The tire is a shinko 244 (golden boy) 17 x 2.50



New air filter, with fresh oil


I picked up this MINT speedo off ebay for a song. If not for the mileage, I would have sworn it's NOS. Still needs a cable though.



Just need to finish the wiring and adjust some cables at this point.
The capacitor pack I made for my magnum was toast. It obviously got too hot at some point. I may end up going with a battery after all. I just need to find a 12v battery that will fit.

look for a slim lithium one lightweight and very small but pack allot of cranking power, the bike looks goo by the way.

I love DRATV. They're such a great resource for parts and info!

Quick update: I got the beast all wired up! And everything works!

I ended up just going with a XTAX4L-BS battery from my local batteries plus, then wired everything up following the CT90 wiring diagram made by Jon Pardue of the Honda Clone group; It's a great source of info on everything to do with small honda clone motors.

Now I need to make something to hold the battery in place... I'm leaning towards a black rubber bungee. Modified a bit, of course.
