Jake, if your ignition is electronic, you may not have enough system voltage to run the starter and the ignition at the same time.
Try with a jump from another vehicle. Likely it will start.
Try bringing the battery to a full and complete charge, water up first,
then retest starting. Some units just have to have a perfect battery and state of charge.

    Hi, thanks for the response. yes, it is electronic ignition. I bought a brand new battery for it before i started the project. had it on a trickle charger before attempting to start it. it has plenty of power and spins the engine over with ease. i already tried starting it with the starter wire disconnected and using my starter button to bypass everything. still nothing. but as soon as i pull it , it starts..?? In my thinking, by bypassing all of the bikes electronics and spinning the engine over like you were using the pull start, it should start. right? its producing its own power from its stator. just a little confused.

SOURCE: no spark

It sounds to me like the repair shop has connected the ignition wire ( the wire going to the + side of the coil ) to the wrong switch terminal. Take a volt ohm meter and connect the ground wire to the negitive ( - ) side of the battery and expose the ignition switch terminals. With the switch in the OFF position check for volatge on all the terminals. Make note of any terminals showing a 12 volt reading. That is probably the feed line from your battery. Turn the switch to the ON or RUN position and check for a terminal other than the one which gave you a reading before. note and mark this terminal. Locate the coil. There are 2 thin ( 18 guage ) wires attached to the coil. One goes to the distributer and the other goes to the ignition switch. Isolate that wire and reattach it to the connection on the ignition switch you marked earlier...
Good luck,

SOURCE: Yamaha 2001 Raptor 660, need to clean my carb

Drain and replace the gas with fresh.
Remove the air cleaner and spray carb cleaner into the inlet. Work your throttle a little then put everything back together and try to start it.

350 big bear quad bike won't start unless I pull start it.


Hi, Connor and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a load test if necessary, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Bank angle sensor tripped and ignition/light key switch not cycled to the "OFF" position and then back to the "ON" position.
5. Faulty ignition switch.
6. Faulty starter button.
7. Faulty kickstand or clutch pull in switch/sensor.
8. Security alarm needs a reset.
9. Starter control circuit, relay, or solenoid faulty.
10. Main fuse or circuit breaker may be blown or faulty.
11. Electric starter shaft pinion gear is not engaging or over-running starter clutch slipping.

I have a yamaha big bear 350 engine bogs down when climing a hill


Could be a problem with a bad float that is overloading the engine with fuel. Does it take a little bit to "clear its throat" once you are on flat ground again?

Smack the starter with a hammer or a wrench if the starter isn't turning over then it's bad if it does crank and won't start your CDI may be bad you've all ready replaced the little stuff sounds like it your starter is bad hope it not CD I if it is replace the stator as well and buy them on ebay it will save you a ton of money

I have a yamaha 350 electric atv. new battery fully charged. when i try to start, i get a click from selinoid.


The click means your starter button is working. Follow the positive cable to the solenoid. Now jump the battery cable to the starter cable, if the starter turns over, you have a bad solenoid. If this does not work,hold the starter button and gently tap on the starter with a plastic hammer. If the starter works now you have bad starter brushes. If you open the starter and the coils are burnt or the armature is shorted you will have to replace the starter assembly.
