Starting from 0, need some advice

scubaru89,

To answer your question on the magnito output it is 6 volts (white wire) but you would be robbing power from the motor by using it and it's just a trickle, not sure of the amps. There is a company called Wonderful Creations that sells through eBay and they have a Generator unit you mount on the other side of the magnito that works Great. This is the site -

They have it for 6 volt output and 12 volt output. They also have a little Charger unit you can add with it to charge a battery. I had that setup on my last bike along with the small motorcycle battery and a power inverter. I was able to run my lights (all LEDs) plus charge my laptop, my iPhone, or even power a regular household light bulb. It was kinda' cool actually.

For my lights I used one of those Bullet Headlights you might see on older bikes and gutted it out. I found a company that sold LEDs for about everything and bought a dual intensity cluster and just glued it into the old bullet light. It gave me a pretty bright low beem and high beem headlight. Also impressive. They also had LED lights for 6 and 12 volt systems that you could just take the old bulb out of a car tail light and put the LED in. That simple. So I had a trailer tail/brake light I got from the auto parts store and just put a tail/brake dual intensity LED in it. Did the same for the Turn Signal/Running lights front and back. Here is the site for them -

You ought to take the time to go through these two sites. Might give you some great ideas.

I haven't read all the posts...much too long for me. These engines have some issues, in order to minimize the issues here is a list of things that I do to a HT before ever thinking about mounting a engine in a bike frame. I have or should I say had 66cc on all the bikes I build, and never a shiftkit...didn't need one on a 66cc, don't know about the 49cc.

Al, you're going to scare the poor guy away. If I'm to understand you correctly you suggest a complete engine teardown and rebuild before trusting it? This post was a decision making help request on buying the right setup. My last motor had many many miles on it from 2009-2012 and I never had engine trouble. Unless you consider not enough power to haul me and a trailer up a hill as trouble, but it ran great otherwise. In fact I have read many posts where people have hundreds plus miles without a problem.

I do agree with one of your tips though, the spark plug wire leaves a lot to be desired and should be replaced right from the start, but the rest is more suited for a rebuild or engine mod post. As for the shift kit, it is a must have for anyone living in a hilly area or someone who weighs very much. I'm 220 lbs and going up hills puts a bit of a strain even on a 66cc motor.

Thank You for taking the time to add your input, but reading the post first is probably a good idea.

Now I will admit his link is quite overwhelming however I can take away some pointers from it. Will I completely tear down the engine? No, but I will consider opening the cylinder and take an overall look at every component on the engine, upgrade the few features mentioned and do the things like change out the coil pack and seal the wire harness. Plus I'm a machinist so I have more than enough knowledge, machinery, skills and material to properly prep components of this engine.

As for the shift kit, where I go to school it is fairly flat and I only weight 180 lbs. However I would like to eliminate the sound of my future engine running at 3000 rpms when I'm trying to cruise at 25 mph, I'd rather take the strain out of the engine by keeping it running at lower rpms. Plus I don't want to be heard coming from 4 blocks down the street, haha.
 
Well Scubaru89, sounds like you have a pretty good handle on what you want to do now and this post has about run it's coarse, so I think I'll back away. You are fortunate to have the tools you will need to do the kind of work you're talking about. I don't have a torque wrench which is necessary for a cylindar head removal, heck, I'm lucky if I can find a 10mm wrench where I am. But if you have it plus the extra time, then it could be educational to see exactly how things work inside one of those before you actually are forced to tear it down. Besides, they give you a free extra set of gaskets with the motor so you might as well use them, right?

I Did save a copy of the information on Al's site. I didn't mean it was bad info, what I meant was that it didn't pertain, but I guess maybe it did if you got something good out of it.

I wish you the best of luck with your build.

Regards....
 
So I still have one questions left unanswered. Who is a better supplier?

SD Stinger seems like a simple company but they only offer a 30 day warranty. Bike Berry and Kings both seem like leaders of the pack but are they as good as I think they are?

Should I go with a Mega Motor, Flying Horse, Grubee, or other?
 
Can't say for sure about Grubee vs. Flying Horse, my bet is they are both the same China Manufacturer so either one won't be a significant difference. To answer about Bike Berry or Kings, I have heard Kings is horrable at honoring anything. If there is something missing from the box they will make sure to blame someone else. Far as Bike Berry goes I'm not sure, I just know they mark the prices higher than a lot of them. I ordered my first one from PistonBikes.com back in 2009 and didn't have any trouble. This motor I just got plus several parts sense 2009 I have ordered from Gasbike.net and haven't had any trouble there either.

One Company I would stay as far away from as possable is Bicycle-Engines.com. I bought a 4 stroke motor from them a while back and a week later the transmission came apart. What they said was "That transmission was origionally for a pocket bike and has known issues" They said they won't replace it but recomended that I buy a new 4G Belt drive from someone else. That was the last time the 4 stroke was used. 1 week.

Punch some of these company names into the Forum Search and see what you come up with, or maybe google "company name" complaints. Fact is, I doubt any of them honor a warranty. All they do is take the box they got from China, put that box in another box and ship it to you. If something is wrong you will have to deal with China, buy a new part, or make one yourself. These guys are out to make money not give stuff away. I also heard that King's is the same company as some other company (can't remember who) just with two web sites and two names.

Most of this I think I got right from This Forum.

I have been looking at the Flying Horse cause its an angle fire head and from what I understand that has a little more power than straight spark plug.

Now as for the seller I have been looking all over at reviews and they all seem to have their few complaints, some way more than others. I just want to know that they are at least reputable in terms of offering some care of their customers. I have also found the prices seem to be at par with the competition, some places offer lower prices but they are either sold out or the kits look like they cheaped out. I think I'd rather pay the extra $20 for a better looking kit.

One last thing, the carburetor. I hear things about some are horrible and others work decent, what type should my kit include?
 
I wish I knew everything about everything, but I just know some things about a lot of things. Now give me a 1964 VW Bug and I can do anything. :) What I know about the Carbs is that on the older models which are still shipped with most kits have fuel jet issues. Not sure what those issues are but I do know that people keep switching out the fuel jets due to poor air/fuel mixture. There is an idle screw, but no way to adjust the mixture other than messing with the jet. One guy soldered his closed and re-drilled his own hole size. The kit I just bought (haven't installed yet) came with a High Performance Carb and it has air/fuel mixture screws but they have both been plugged. I'm going to attempt to unplug them. The altitude of where you live has a big influance on your engine running rich or lean and that affects power and gas milage. I have never really learned to read a spark plug. Mostly because a black plug could mean so many things and with a 2 stroke (oil/gas mix) it screws me up. Sorry, no help here. All I knew when I ordered mine was the last carb (the cheapy one) kept fluxuating and that was irritating, so I made sure that this kit was a newer model with a different Carb, and yes, I paid a little extra to get what I wanted the first time. I figured if I had to change out the Carb then a new High Performance would have been more than the extra to have it come with the kit. Don't know why it is, but I also discovered that the 49cc is more expencive than the 66cc.

You can never know the reputation of a company if you don't listen to the complaints. Yes, a lot of companies have their complaints because as I said before, no one wants to be responsable for the China Company not packing the box correctly. I generally read the complaints when available and filter out the stupid ones. Stupid ones usually come from people who you have to explain "lefty loosey righty tighty" to. I DO red flag companies that have serious complaints such as the business I had with Bicycle-Engines.com or the complaint I read from King's.

You are basing your idea that a better looking picture is a better quality kit. China Gas puts out just about all of them. In fact I would even venture to say that you could take your Grubee cylinder off and put on a Slant fire and have a Flying horse. You might even be able to put a 66cc top end on a 49cc bottom end with no modifications. So if you want to spend the extra $20 bucks, spend it on the company that didn't have any bad reviews and you'll be doing yourself a service. That's my opinion anyway.
