    I bought my first kit this weekend. No namebrand, but it looks like the kit sold by Spookytooth. I got it from a guy who's trying to start a buisness out of his home, but I got it cheap. Its suppose to be 80cc, and the kit looks well thought out.

    But, the guy who sold it to me said you "Must" pedal to start out.
    Is that the case? Are there ways to make this work like a normal motorbike?

    I come from Ebikes, and have grown used to riding around on a motored bike, being able to use the bike as a pedal cycle, or a motorbike at my discresion. I'm used to being motorized, but totaly clueless about 2 strokes and bicycles. any advice or warnings would be greatly apriciated!

    First of all, I'd just like to thank you!! Your older thread is what inspired me to write the Crash Course. I was tired of not getting basics across to noobs in an efficient manner, and I wanted to make sure all newer posts were something worth taking the time to read. Hearing that phrase - "read, read, read" - from 4 separate people in the same day, when there are now more than 100,000 posts on this forums, was ever so unproductive.

    Anyway... a 33cc engine can push [most] anyone from a standstill on flat ground without pedaling. Weight, hills, tire size, etc. will all affect the starting and top-end speeds. Only way you'd "have to pedal" when starting is if the chain hooks up to the crank without a freewheel and requires you to pedal all the time, not just when starting. The only real way to figure out how fast it starts out and tops out at, tho, is to put it on!! The guy most likely meant to say that you "should" pedal while starting out... as it saves the clutch pads, gas, and does get you up to top speed quite a bit faster.

    And your engine isn't 80cc. There is no 80cc that I'm aware off. True displacement of these engines range from 66cc to 69cc. The more honest sellers of these kits claim they are 70cc, which is obviously more accurate than 80cc.

    G'Luck!

    That crash course is a good thread. I read it before I bought the motor I have, and it convinced me to go for a 2 stroke.

    Also good to know about it's true displacement. The instructions said the 80cc has a 7mm longer stroke than the 50cc, but that didn't seem to add up to a 60% increase in size.

    As for the clutch, i haven't been able to find much on it. without a name brand, its hard to search, and "Happy Time" seems to cover a wide range. All I can tell is that it looks like the spookytooth 2 cycles, and the guy who had it seemed to think it couldn't be feathered like a real clutch, that it was either on or off.

    I have 2 70cc HTs, you HAVE to pedal to get it going - it just is what it is, you'll see.

    Is it because of lack of power, or is it a clutch issue? I don't have a bike frame yet, so still trying to understand how it works.

    There is no pull start on these engines, the only way to start them is by pedaling with the clutch disengaged, then when going 5-7mph let the clutch out and the chain will turn it over and get it running.

    Also, the clutch is NOT a centrifugal type, when you come to a stop, you either must disengage the clutch, or kill the engine by means of the kill switch.

    Engine will start on your first pedaling attempt though, so no need to worry!

    That part I understand. I have a Peugeot 103 Moped i'm messing around with too, it starts the same way. Pedal up to 4mph, and it fires up. (or pedal it up on the center stand)

    What i was concerned about is after the motor is running, and you've stopped, but the clutch is pulled and the motor is running. Can you let out the clutch and have the motor pull you from a dead stop (Like a normal motorbike) , or do you have to pedal to get rolling?

    As far as the way I do it.....

    If pulling up to a stop sign and coming to a dead stop with the clutch engaged.... I myself will normally give it one or two rotations of the pedals and then release the clutch.

    Some may just relaese the clutch and give it throttle, but for me this seems to be the smoothest way of doing it.

    It will pull you from a dead stop, however if you continue that practice you should
    buy stock in a clutch plate company.

    The guy that runs the boygofast store on eBay has a pull start listed for sale. It's supposed to go on the engines that he sells. I personally don't see a point to it since pedal starting it is so easy.

    From my own experience, which isn't much, I always start pedaling first and get some speed up then let out the clutch. By the sound of it, I can tell that the little friction clutch plate is not going to last to long if I were to dog it from a dead stop. You can just sort of hear it.
