depends on where the metal broke off from. be more specific on where the pice broke off from? if your not sure investigate a little more.

if you are getting gas, it's probably too much. is it flooding the motor. make sure your float level height is okay and that your float needle valve assembly is clean and not sticking. if you have an electronic choke, try disconnecting it. it might be malfunctioning. also a possibility your valves need to be adjusted.

Nice so how do you get 4x4 training wheels?

Hi,
My first thought is the plug wire. You can check it by connecting an ohmmeter to each end and measure the resistance. If the meter pegs, then the cable is bad. Another is to make sure you are getting juice to and through the ignition switch. If it sat outside, the weather may have ruined the switch. Check all your wiring and make sure there are not any breaks. I have seen rodents take up residence in carts, motorcycles, snowmobiles, and ruin an entire electrical system. Let me know if I can be of more help.

what to do with fluids?If your brake fluid is in need of changing do so before long-term storage. Similarly hydraulic clutch fluid should be changed before you store your bike; both systems may suffer failure if moisture gets in. Also make sure your coolant is fresh, as deposits can form from old fluid. For service intervals, consult your owner's manual.,,,

try a new spark plug and carburetor cleaner in the gas

Yes, the size.
YTX 7 is 6 Ah.
YTX 9 is 8 Ah.
Both are made in China.

does it have a compression releaf and is it bent if its open any it will not start

no its all that oil in the fule tank the oil is to thick to go through the carb jets,,fix the oil injector pump

The fuel mix is too lean. Chances are the rubber seals from the carb to the cylinder need to be replaced to prevent un-carbureted air from getting into the fuel/air mix.

Just follow your owner manual book. There are many sizes/types of spark plug in market with different applications.

Remove and clean the carb with spray carb cleaner.

Try checking your carb ,the main jet might be in need of a clean.

first get the bike running, turn the idle adjustment up enough to keep it running. start with the air/fuel screw, 1 1/4 turn out. adjust the screw which ever way increases the idle 1/4 turn at a time, wait 10 seconds after every 1/4 turn to allow the engine speed to adjust. As the idle goes up you can use the idle screw to keep it in its normal range. at some point, the idle will start to come back down, this is when you want to start going the other way. idealy you want it set in the middle of the range of when it stopped increasing and when it started to decrease. If you are not able to reach this happy medium within the normal adjustment range, you will need to put the proper pilot jet in and start the process again. This should get you up and running, if it is a generic carb you may will have to adjust the jetting to get the bike performing its best after that, but thats another chapter.

i would try a small engine repair shop that repairs lawnmowers and chain saws,bring the piston or ring there, you may be able to get one
