    I am not very educated about motorcycles. I was searching craigslist and found a 1962 Murray bike with an 80cc BGF motor for $320. The man says the bike works fine but after doing some research it seems BGF has mixed reviews.

    I am not mechanically inclined and really just want something reliable and sturdy. I just like interesting toys but don't want to waste money. I plan on riding this 2 miles to work everyday.

    Does anyone here advise buying an 8month old use BFG or suggest buying a new one off ebay? I am a little intimated to build on my one but if they are easy I could try.

    It just depends

    On how much you want to spend. 300 bucks for a ready to ride is not much money... I would test it out real good.. I built a golden eagle (gebe) and its super reliable. Japanese quality engine.. But it cost around 1000 total. But will last for years. The deal with the chineese kit is that they are very cheaply constructed and will require you to work on them!!! Its just the nature of the beast..So if you dont know anything about engines you might have to find someone to help you.. Some of the chinese engines last a long time.. Its a **** shoot!!! If you want rock solid reliability then get a tanaka,robin subaru, or honda or mutsubishi engines..
    Happy hunting !!!!:cool2:

    The thing here is that boy go fast does not manufacture the engines that he sells.
    He's just a drop shipper and all of the engines and kits that he sells are made in china.
    The reason that boy go fast has mixed reviews is that an occasion lemon of an engine will get sent out (this happens with all vendors who sell these kits.) but his customer service is not very good. But, if you didn't buy the engine kit from him, you won't need his customer service anyway.

    Almost all china 2 strokes that are made for bicycles are the same engine (altho they are all built in different factories). i have bought several engine kits from boy go fast and i have not had a problem with any of them.

    The key here is how well was the bike built and maintained?
    How well was the engine installed, is it done right? Look at pics of assembled bikes here to get an idea of what looks right. If the bike has a hole drilled in the frame for the front engine mount, it can cause the frame to crack.
    How many miles does it have on it (approx.)?
    Does it have all of the stock original parts on the engine like the spark plug, exhaust, spark plug wire, air filter.
    If it does, you may want to consider upgrading / modifying some of those parts with better ones (this can be done fairly cheap). There are a ton of things that you can do to it to improve the power, performance and longevity.
    The stock exhaust can get clogged up with oil over time, reducing the performance of the engine.
    Is the wiring done good? (all stock connectors removed and all wires soldered and heat shrunk? Wires not hanging all over the place?
    The majority of failures to bikes with these chinese 2 stroke kits is due to incorrect installation, incorrect oil/fuel ratios and no maintanance.
    $300.00 is fairly cheap, providing that the bike/engine was built right, looks good, runs good, isn't worn out and has been maintained.

    A brand new engine kit from boy go fast (or any other e-bay vendor) will set you back around $120.00 - $140.00 depending on who you buy from. A bicycle itself can set you back anywhere from $100.00 -$300.00 alone depending on what you want. Then you have to figure in the time it takes to install the engine kit because most of the time, you have to modify something to make them work right. You should figure on a weekend to get one of these bikes assembled if you have never built one, or have very little mechanical ability and limited tools.

    Make sure that the bike itself is good, no loose bearings, wobbling wheels, bent wheels, broken spokes, good brakes, etc.
    if the bike is good, the engine runs good, is installed correctly (or what looks to be correct), and the wiring is good, then i'd say you're safe.
    BUT, sometimes with these engines, you never know when they are going to develop a problem because they are all cheaply made, and they are basically throw away engines (altho they can be re-built if needed).

    So look at it this way. You could buy this complete, running rideable bike for $300.00 vs. the hassle of ordering the engine kit, finding a good bike for a decent price and then assembling the whole thing. You'd still have probably around $200.00 - $300.00 in one if you built it yourself.
    The chance you'd be taking with buying a used bike is, how long will it last once you get it?
    Unfortunatley, no one has an answer for that.
    you have no idea how the previous owner rode it, maintained it or assembled it.

    i bought two engines from bgf so far and both of them had so many problems that he wouldnt help me, he didnt even offer to send missing parts that werent shipped to me, i had to buy an entire top end kit, because the engines has holes all over the cylinder, my advice would be to never buy from him

    Don't waste your money

    Two miles? Just use a normal bike with pedals, unless there's something wrong with you that keeps you from being able to ride ten minutes at a relaxed pace.

    That Murray was a cheap hunk of junk when it was new, and now it's fifty years old. You'd be much better off shopping for a good used bike (NOT a department store heap) for $200 or less, budgeting the remaining $100 for a tuneup and whatever replacement parts are necessary to get it working just right.

    If your bike has to have a motor and it has to be reliable (and you won't do the work yourself), then you had better budget a heck of a lot more than $300 for it. Think more along the lines of $1000, and shop around for an obliging and skilled mechanic before you buy anything. You may have difficulty finding someone who has the skills to wrench on a motorized bicycle well, who's also willing to mess with one at all.

    you can get fully assembled motor bikes for around $500 from many of the online dealers, and you will get a better bike and an un-used motor.

    And yeah, pedaling two miles is not hard if you are in generally good health. But I understand the appeal of cool toys-- maybe for you, riding it to work is not the purpose, just a bonus.

    I want the bike and gas engine really just too have and to show off....Of course I'd like to ride it to work every day.

    I work for a "picking" business (cool antique motorcycles, signs, that stuff) and really just am constantly inspired to collect weird things. For $1000 I'd rather just buy a real motorcycle! $300 seems like a good deal as long as this thing can run well for a year then I'll prolly sell it or just keep it in the garage to look at.

    Yeah, His stuff is cheap. But if it works, It works. (sometimes it dont.) The used bike idea can work but I suggest you find someone in your area that knows about M.Bs to check it out for you. Ya don't mention where you're at, but if you were in my area I'd check it out for you.
    If it runs well now I think the worse case for the near future would be a clutch replacement or a top end rebuild. Both are cheap enough.
    Ya don't sound like you're trying to make a lifetime commitment out of this anyway, and $300. is a good price for a summer hobby. So I say go for it. Have some fun untill you're tired of riding or it blows up, Whichever comes first.

    I also say go for it. I live 3 miles from work and pedal in sometimes just for the exercise and to save a few bucks in fuel in my truck. I just put a motor on a genesis onyx 29 cruiser bike to ride into work with. I didn't need the motor but thought it would be fun. Go for it.

    62 Murray.

    Yeah ddesens, He don't wanna marry it, just ride it for a bit then park it. And sorry Chalo, gonna have to dissagree with you a little bit about the Murray. In 1962 the bike was most likely made right here in the good ole U. S. out of good ole U.S. steel. As long as it's not rusted through anywhere then worse case you might need to replace a bearing or two. Few bikes are made in the U.S. today and those that are, most "poor folk" can't afford. So, what yer saying is for him to buy a (most likely) chinese made bike (From wall mart?). Then order either a $300 to $600 GOOD engine, or a $150 2 stroke that may or may not run when he gets it. (MADE IN CHINA stamped on the box.)
    In "62" the Murry was a good middle of the road bike made of STEEL, The engine thats on it now RUNS. $320. is a O K price. I don't know why anybody would voice in a negitive about this. Of course I would try to talk the guy down on the price a bit, but other than that, I would GO FOR IT.

    What is wrong with that bike can't be fixed or replaced. I say this as a professional bike mechanic who has given his shop a reputation for being willing to service any bike, no matter how old, cheap, or weird.

    The steel in a 50 year old Murray is probably good. Weak, but good quality, tough and consistent. But that frame probably weighs at least ten pounds where a modern steel straight-tube frame would weigh five and a modern aluminum frame four. It's made out of small diameter curved tubes, so it doesn't even have a stiffness advantage in return for all that weight. The dropouts are almost certainly so thin as to become bent in ordinary use.

    It probably doesn't have any braze-on fittings for attaching fenders, rack, bottles, and other accesories. All the bolt-on stuff was expected to crowd onto the axle where it complicates assembly and where everything gets crushed and smashed under the axle nuts when they are securely tightened.

    The joinery in a cheap brand American frame of that age-- and Murray is definitely a cheap brand, like Huffy-- is usually internal fillet. That is to say they dropped a ring of brass in each joint during setup, then cooked the thing until the brass just began to show on the outside. It looks tidy (like there is no weld at all), but all you know about a joint like that is that the filler made it all the way around (probably). The brass can easily be all piled up on one side of the joint, leaving the other side weak and prone to cracking. But to be fair, the steel in those old frames is often so soft that the frame is likely to bend before a joint lets go.

    The bottom bracket cups on a bike like that old Murray are likely to have flared out the softer bottom bracket shell, leaving it unable to be properly adjusted or to have a new BB securely installed. The headset is screwed up by design, with a fork crown race that slips over the fork steerer without pressing on. (They did that to save costs.) The result is a headset that you can tighten properly or even grossly overtighten, but which will still knock and shift around like it's loose.

    Handlebar stems and seatpost clamps on those old bikes, like on the cheapest kinds of new bikes, were mostly crudely stamped from sheet metal, and they crimped the handlebars or seatposts when securely tightened. Some stems were sandcast steel, and these look cool but are likely to break off down below the headset top nut.

    Old Schwinns were very strong and came with durable components, but old Huffys, Murrays, Roadmasters and Hawthornes are not Schwinns. Department store bikes of the 1950s to 1980s were comparable to Soviet bikes in their build quality.

    No way would I ever recommend that anybody get a department store bike these days. They are even worse now than they were back then!

    For this job I recommend a used steel mountain bike from the 1980s, before suspension forks or aluminum frames came into broad use. An '80s MTB will be made of strong steel in medium diameters, with a full complement of braze-on fittings and thick forged dropouts. For a newer model, a bike designed for loaded touring is a better choice, since most touring bikes retained all the most important features of '80s MTBs.

    Either one of these things cost the equivalent of over $1000 of today's dollars when it was new, but can now be had in good used condition for a fraction of that.

    A '60s Murray was made of steel. It was neither middle of the road, nor good. It was a cheap bike with some virtues that were common to American industry, and a lot of drawbacks related to its price point.

    Have you ever had a good bike? Like one that cost more than a couple of weeks' wages when it was new? That was set up and serviced by a good bike shop? There is a difference-- which is well worth the extra cost if you ride regularly.

    You're right Chalo, A $1,000 bike would be better. And yes, Schwinn did make a better bike in the 80s. But dang, Let the guy ride. Like I said before, till it blows up or bends or......
