    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.

    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. :D

    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

    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.

    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.

    I took the trail140 for her first bit of trail riding yesterday. Such a beautiful day, I couldn't pass up the chance. I didn't go too far off the beaten path before turning around, but it sure was fun. I still need to do some carb tuning, otherwise she did great.

    Later that afternoon I lost all charge in my battery while on a ride through Nashua, NH. I don't think I had my rectifier hooked up correctly, so the lights just sucked the charge from her. Luckily I installed a switch that negates the need for a battery to run the ignition.
    I got her re-wired and she's putting out a steady 8-12v dc from idle to mid throttle. Hopefully my battery will take the charge.

    The 140 engine does make it fun.

    Reading this made me push out one of my CT 110s and put it up on the lift to get running. They are a fun fun bike. Enjoyed your build. I would like to find a yellow 90 as they are just cool

    This site (http://www.dratv.com/index.html) may be worth your time looking at. They have compiled a lot of little parts that may come in handy.

    I've only bought ATC parts from them and have had good service.

    Cool build. And like was said earlier, every Honda Trail bike around here goes for stupid money if it can roll.

    I've ridden one these before, very fun. It may be the best modern successor to the Trail 90/110

    Great write up. Exactly what I want to do. I grew up on a 69 ct90 and really want to find a basket case for a nice retro rebuild.
