2 stroke

I'm going to be building my first motorized bike soon, and have heard this stuff works wonders. I'm just completely unaware of which bolts to use it on. Also, any other suggestions or recommendations would be greatly appreciated.

I'm planning on getting a 2 stroke 66/88cc kit with a SBP jackshaft and i want to basically have a mini dirt bike. I'm looking for a base bike that's 7 speed and maybe has fat tires. If anyone's ridden in loose dirt with a normal mountain bike vs a fat tire your opinion on whether a fat tire is...

I've recently purchased a 66cc motor from the internet and installed it on my bicycle. It ran great for about 15 minutes before refusing to turn. It seems to be the front drive sprocket (the smaller one) that just will not budge no matter what I do. Considering sending the engine back for a...

Hi guys, having trouble with my engine its a china dolphin harbour a80 (62cc). I have ruled any other causes and found the problem to be the CDI. Anybody know any good replacements and what price range im looking at? Thanks!

i bought a brand new generic Chinese motorized bike kit off eBay the other day. It's a 66(80cc) kit with a slant head. After installing it I couldn't get it to start. I'm sure it's getting fuel because the plug is wet when I pull it out. I've checked for spark multiple times and I only SOMETIMES...

How long did your china girl last? How many miles did your 66/80cc 2 stroke engine last? Where did you buy it from. How many miles did it go before you had to replace a part? What was the part?

Is buying a kit from ThatsDax worth the extra $100-150 dollars? What kind of issues do eBay ones have? will engines from ThatsDax have significantly less vibration? I not actually buying this to put on a bike. I am building a very compact compressor. I thought these very small 2 stroke...

I am new to this and i am very confused. ThatsDax seams to be the top rated vendor on this site. But on this page it says that his engines are "China, Titan." http://motorbicycling.com/showthread.php?t=1730 What does that mean? I thought everyone said Chinese engines require a lot of work. does...

If i have the entire kit that came with my 2 stroke engine, and wanted to get a 4 stroke, could i just get the engine and use all the parts i still have, sprocket, throttle, clutch, everything, on the new engine. and if so, would i go any slower or faster with the sprocket that came with the 2...

Hi Guys. I have been doing some research on engines for my new build that you can see in the board track section. I was wondering what are your thoughts about the thats DAX KMT clone motor. It is 500 dollars, but you will be getting the 9 hp and so on. Maybe you could recommend something...

So I got this kit. The engine came with a centrifugal clutch and pull start already installed on it. What I want know is this: How the do I remove the centrifugal clutch? I've looked everywhere and can't find a solid answer.

Hello everyone! This summer I have planned to build and sell motorbikes for some easy cash. I am not the kind of person to constantly update a thread with everything I do, so I am only going to post when I finish a bike, and will update the post when I sell the corresponding bike. I really don't...

Got this bike for 150. Motor hadn't been broken yet but bike had sat for 2years. Took her apart cleaned everything but the block , greased her up and replaced whatever bolts and studs I could find from ace. Started up easy but kinda ran a little rough sounded like something was clanking behind...

I have an 80cc 2-stroke beach cruiser. So I checked my CDI with a Voltmeter and im getting a reading of 7.7 at 20k ohms.. I read that it should be at 2.3 new. does this mean my cdi ignition is bad?... I was riding it up a slight hill at full speed, and when i slowed down and pulled in the...

Hi, I'm brand new to this. I've read a lot on the web, but most articles seem to favor whatever they are selling. I want to build a bike, and I'm not sure if I should go 2 or 4 stroke. I know the 4 stroke is more $, but would I get more torque on hills, etc? Are they substantially...

Is there a big bore kit for these 2 stroke engines?

I am on my way to WalMart now to purchase my first bike frame. I am having a hard time deciding between Roadmaster, Huffy, or Shwinn. I plan on video taping and posting pics and comments of my entire experience with my first motorbicycle. I have already ordered my kit from boygofast, and will be...

I tried a lot of different muffler end cap fixes, and in the end they all kept falling off one way or another. I jb welded a soda can to the end and then put a screw threw that, and the screw loosened and it eventually fell off, then i went to using a washer with some drilled holes in it...
