problem

this motor will not run wide open. it gets up a little above idle then stumbles then dies. what are some symptoms of a bad coil? any aftermarket head gaskets out there?

I'm new to minibikes so I have some questions that someone here may be able to help me with. First I will put you in the ball park, then describe my problem and ask questions. I have a used and abused Baja Warrior with the original clutch, jackshaft assembly, and bearings. The clutch...

This may be helpful to someone in the future because when I had the problem with the recoil trying to rip my arm off, I was told the compression itself was the cause then all I kept reading was valve lash. I was searching for troubleshooting and repairing compression release on clone cam. I...

i'm looking at a newer model doodlebug that a guy is selling as just a frame. he says it will run but foul the plug pretty quickly. i'm guessing oil is mixing with gas which can't be a good thing. if that's not it then what else could be causing the problem? i'd like to buy it for my kids...

I have a predator and it starts first pull everytime but when you take the choke off it revs as if it were the throttle. It ran fine before we put it in the frame. Ive taken it apart multiple times and cant find the problem. Any suggestions on where to start looking? All help is appreciated i...

Today I was enjoying a ride when my chain came off. It sounded bad. I know my tension was tight. I even have the tension washers on the rear and every thing turned and was lined up without any bind. I'm wondering what could have caused it. Because the chain is still in perfect shape! The chain...

Ok, so I replaced my kids doodlebug carburetor with a jetted carburetor, but when I was done and started it up it was full throttle all the time. I noticed the throttle arm that opens and closes the top of the carburetor, the arm just stays open and never gets pushed back to let the doodlebug...

I have an elderly 3HP horizontal shaft B&S powered lawn mower which developed a problem where it would start and run for a minute or two and then stop. I found your forum had lots of really good advice and have followed it to identify that it has a pulsa jet carb which can result in this...

Just installed a TC2 Torque Converter. I'm afraid to start it because the belt is "engaged." So much so that when I push the bike with the engine off it turns the motor over. Has anyone had this problem and what did you do to solve it? I double checked how everything is installed and all...

Hi, first post! first problem, my flyweight in the driver popping out high rpm and gets stuck! The tav2 is brand new, so the springs should be ok.:shrug: R Sala

it seems to just die after a quick sprint .. removed the low oil sensor , and tried the "open" the cap trick .. even rode with it off... runs strong and just dies... what gives? Very hard to start after it shuts off, gotta let it sit . Im 220 lbs hitting 46 mph on a mini bike. any...

Just finished breaking the 212cc engine in (only scattered bits of tiny dots of metal on bottom of oil drain bowl). Always starts right up with choke on, BUT after a 1/2 a minute or so I take the choke off. It runs but won't rev up, then after a while it dies, so I put the choke on and it starts...

Started on my Black Betty wannabe. Got a 86 KX80 for the front end and have a warrior frame on the way. But as I'm getting ready to cut it's head off I take one last look and see a possability, maybe a better possbity. Keep the frame with great brakes front and rear and a swing arm, new rubber...

I have a 1975 Suzuki 2 stroke dirt bike that has a Mikuni carb on it. I am having problems with the carb to throttle linkage. When the twist grip throttle is put together properly the carb is 2/3 open and won't close. :doah: At first I thought the throttle cable was too short, but it is the...

I've got a 70's H35 that runs and idles good. Just tuned up and rebuilt carb. The problem is that when not running, gas will run out of the back of the carb. The cheap fix has been a gas shutoff valve at the tank. My guess is something not seated correctly and allowing gas to push by in the...

Picked up a attex awhile back runs good and I even have the recoil for it but the transmission slips.What can be done for rebuilding these Thanks
