How about a 49cc Lifan 4 stroke to clear the air?

    I see the argument for our beloved 2 stroke HT's but if green is our ultimate goal then lets consider a catalyzed 49 or 70cc Lifan engine. It would probably be easier to get tagged as a special construction motorcycle and sidestep all the legal mumbo jumbo for mopeds. The engines are completely reliable and have been used in Asia for almost 50 years. A little re jetting and a catalyzed exhaust and we have a 50 MPH /100 MPG motor-bicycle that is clean running and still a really inexpensive way to get about. It would also take off our restrictions for speed and allow us to run headlights, turnsignals and a HORN for the cagers that are too busy texting to pay attention.. IMHO:jester:

    Ya, I don't know why more people don't attempt to use the Lifan-honda clone motors in mopeds. I've been riding a Motoped for a year now that uses a Lifan 4-stroke motor, I like it way better than any 2-stroke. Check out motopeds dot com. A catalyzed exhaust does sound like a good idea though.

    With a Lifan Honda clone, what you've basically got is a motorcycle. Even the 50cc models have multiple speed gearboxes which qualify them as a motorcycle in most states. You can purchase a fully assembled, EPA/DOT approved, DMV registerable and insurable scooter or motorcycle with these engines for roughly $1,200 bucks brand new.

    You can throw one of the Lifan 140cc variants in an old Honda Trail 70 or Passport 70 scooter and have some street legal 60 mph - 100 mpg fun.

    I wouldn't put a catayst on the exhaust purposely, as these little engines burn fairly cleanly out of the box. The fuel sipping nature of a small MC or motorized pedal bike satisfies the "green" requirement in my book.

    Now thats a COOL Bike!

    Even if I had to get lights n signals on that and tag it as a Motorcycle that is the way to go! Thanks for the link and happy surfing!

    I agree with your point completely Ghost..

    But in New Germany (Jersey) where you cant ride our lil smoksters without possible incurring of a fistful of tickets this may be the only way to get our lil motor on. And it would be a fully usable scoot for around town riding while being completely different. At 50cc's this would be the least expensive MC to insure and run , im thinking pretty much in line with a Mopeds cost IMHO..

    I beat my head against NJ DMV's walls when I was the WD for Grubee in NJ back in the day to get these legalized. I am done with that and will keep my last roundhead 49cc kit for if/when I escape this state and can use it without fear of ticketing..

    IF YOU CANT BEAT EM.. CHANGE THE PLAYING FIELD...LOL:helmet:

    Alaskavan, you sure that Lifan has a CVT? It appears to be a 3 or 4 speed semi-automatic (clutchless) engine. With these engines, there is no clutch lever. You just let up on the gas and shift, then get back on it.

    When you said you had a Lifan with an internal CVT, I was expecting to see an engine like this scooter engine. Notice how long the scooter engine is because of the CVT belt. And $199.00 is a great price. I think I just gave myself an idea.........

    After looking around last night there is a 49cc Lifan "single speed" engine. Im guessing its like a CVT or similar inside but cant get any info on it otherwise.

    I've seen them with reverse for ATV's, and no gears (primarily for youth ATV's) but to my knowledge there are no Honda style horizontal engines with an internal CVT. But hey, I'm probably wrong. The Chinese manufacturers have changed and adapted these designs over the years to fit various applications.

    My engine was designed for a small ATV, has no shifting mechanism, and I don't feel any "shift points" while riding. There is something going on in there, because in a highly tuned version, I could easily take off without pedaling, and I believe the top speed would have been about 70 - 75mph. I never took it to it's top speed before I detuned it (I was afraid that some time, after some adult beverages, I might try it. Also, I was dissatisfied with the approx. 100 mpg I was getting.) In detuned form, last week I rode a little over 132 miles averaging 40 mph on .6 gallon of gas.

    Yes, there is a lifan 50cc fully auto single speed, I got one for my motoped, but it is really slow - they come in little kids quads. I rode around with it for a couple months, let the cops get used to seeing me, then I put in my semi-auto with a big bore kit. Another trick you can do with a semi-auto is take the shifter off while you ride on the street and carry the shifter in your pocket for when you get off-road. If you take the shifter off a semi-auto it's exactly the same thing as a single speed with an automatic clutch - like every other motorized bike.

    Rig a paddle shifter on the handlebars. Just roll off the throttle and shift!

    Van - From your description of top speed (70) and being able to take off without pedaling - either there is some sort of CVT in there or the centrifugal clutch is doing a lot of slipping!

    Is there a model number on the engine? (Like 1P52FMI or something similar)

    Alaskan - I'd like to know that as well, because my fully auto Lifan is definetly only a single speed.

    After further web research there is a 49cc Lifan with a 1 speed box and auto clutch.

    As stated earlier it looks to be used in youth ATV applications and comments stated they were "really slow" with really low gearing (but probably mounds of torque)

    Im guessing for safety's sake so lil Bobby and Sally dont hurt themselves too much..too early in life..:ack2:

    So who has a 40 tooth chain ring for a JC Higgins rear coaster Rim compatible with motorcycle chain??? :devilish:
    JUST KIDDING!

    I think the Higgins is getting my last 49cc kit for shizz and giggles..

    But that Mo-bike thingy looks like my next buildup as soon as I find out if I can tag it as a MC in Jersey and finally scoot around on something legal and more efficient than my 93 Subaru (it only averages 30 MPG..lol)

    I'll try to remember to look for a serial# or something tomorrow. However, I don't recall saying mine is 50cc. I often do say that anything above 50cc would probly be illegal. I don't remember exactly what mine is.

    Looking at the Lifan Group website, they do list some 70-100cc horizontal Honda style engines with auto clutch single speed, and two speed "auto-wave" transmissions. I have no clue what an "auto-wave" transmission is............

    Hey Ghost, what's the address of that that website?

    Lifan.com of course!

    Above link will take you to the page with the "auto-wave" single speed and double auto clutched 2 speed auto-wave (*whew*) engines.
