motor

I have done a fair amount of research into buying a kit for my bike but in the end I have come up short there is just so many brands and different types of engines that I will never through, so here is my question what is the best brand to buy from (I know that in the end I am going to still...

Thinking real hard about mounting my 79cc Greyhound engine vertically. Have the mounts, fabbed up a plywood plate, etc. But I am stuck on drilling and tapping the second oil filler hole. I have seen others use what appears to be a brass hose barb looking thing- are those 3/4" MHT threads...

First off, thanks to all who post and reply with feedback it's much appreciated. So I have a brand new Skyhawk 66 cc motor and have successfully mounted the kit to an awesome lime green cruiser. When I take it out for its first ride, it kicks on for 1.5 seconds and then dies. I have spent...

I have been dorking around with this engine for almost a year. I got some good runs in on it. Then I said screw it and bought a 1995 Vulcan 750 for $1500 with 13k miles on it. Runs like a champ. I may never be back here as long as I live (quite literally). Had these little engines beed solid...

I know the first answer that comes to mind is soap and hot water, but I'm trying to clean off the oil/grease crud off my head and between the fins to no avail. So anyway, what is the best way to get that muck off? Would degreasing agents such as Engine Brite or Castrol Super Clean work...

i have a mongoose xr 75 (24 inch) bike with me, i want a rack with engine mount so i can mount the predator(harbor freight engine) 212cc on its back and ride it, i am kind of a newbie, i have built just one 50cc 4 stroke in my life, so please help. or some mount that will help me mount a motor...

Ok so I have bought a Brand New 66/80cc bike motor off on ebay, installed correctly and everything but it is VERY HARD TO START meaning that every time I try to start it it pedals hard and Im thinking it might be something wrong with the cylindar or what. I am new to the whole bike/motor scene...

So I can get a 600cc motor that pushes 106whp at 300km/h in a go cart was thinking about building a trike with 2x2 tue 1/4" wall and cr500 weels on the rear Any thoughts or ideas

So I got into these things by buying a used motor and bike that I saw on the side of the road a while back.. Since then I decided to build a new bike with a new motor. I bought the motor kit on KingsMotorBikes.com, which I heard wasn't a great idea but I think I got a pretty good deal.. Anyway...

OK so I need some help on a first build. I want to know what motor kits to get. I don't have much funds right now so want to start with a 49/50cc 2 stroke kit but I want to upgrade to a inframe 4 stroke later on, so suggestions on both are needed. The two main things I'm looking for are price...

My original bike frame that I was going to use for this motor broke a few spokes because the sprocket came loose and bend, thus breaking some spokes. Also, because this was a re-badged Huffy bike for Shucks. It had a very hard to find rim size, and couldn't replace it. So I then found this at...

Okay, maybe not in the middle of nowhere, But it feels like it! Live in the Puget sound, right on a small island called Vashon. Anyways, I'm 15, and got my project last Christmas. Yes, this is not my first post, as my first one was ranting about BoyGoFast. I had a very bad week a while ago...

It all started Christmas of 2011, the day I get my BoyGoFast "80cc" (actually 60cc, called in 80cc. Do you guys call a 60c engine an 80cc, because in the instructions it says that that's what the motor bike community calls them?) I managed to understand the horridly translated instructions...

My current project is a gas scooter direct drive. this is a homelite 240 engine, the original Zenoah engine was shot when i bought the scooter. I am trying to set up a direct drive for the scooter. i have exausted my funds and need a cheap solution. i was going to try to use a deepwell socket...

has anyone ordered from the new spooky tooth owners yet?

I finished building my motor bike and I was very excited until it failed to start. I held the gas in and when i released the clutch to engage the engine i heard the engine try to start and fail. The gas line line is fine and there is a switch on the clutch with 2 chinese symbols, i have tried...

Ok, some basic info I was confused by. first: all 4 of the 2 stroke engine kits are manufactured in China and then bought and re-sold under a variety of names around the world. Grubee, Raw, etc.. the exterior specs all the same! do not stress on which hardware and mounts will work. just which...

I’m having a problem keeping my bike running. I just built my first bike with a Grubee GT5 Motor, took it out and it fired up right away with a 16:1 fuel mixture (like recommended). My problem is that I can’t keep it running. If I turn the lower petcock lever all the way to open it feeds way...
