Hi everyone. So I parked my quads last fall for the winter and everything was fine. Now the Honda started as usual, but the Yamaha will just sit there and crank but no fire. Spark plug was good and good spark. Even changed the plug for a new one. Still the same. Disconnected the gas line and there was lots of fuel. Doe this mean carburator or electronics. One friend said heat it up with a small torch. Any ideas would be appreciated as I'm not that knowledgeable about mechanics. Thanks in advance.

If I had to guess, from sitting...the float pin in the carb is corroded and stuck. This happened to my 2004 Kodiak years back after sitting. It's either not getting fuel or spark. Spray some fuel into the intake and see if it starts, then you know it's fuel...take the carb apart or remove it enough to access the carb bowl. I think I rotated it somehow and pulled the bowl off and checked the float movement.

before pulling the carb off try draining the fuel tank & the float bowl completely empty.

then refill the tank with premium gas & seafoam addative (or any carb cleaner/snake-oil addative). leave the float drain open until the gas looks good and then replace the float bowl plug.

remove the airbox cover & filter (making sure the box is clean before removing the filter).

then spray some aresol carb-cleaner (not ether or starter stuff) into the intake and turn the bike over until it runs for a bit on the carb-cleaner. if you can't get it to take then the carb needs to be removed/rebuilt.

If you have good spark, and a good plug, I would take teh carb apart and clean it. Now ive never actually pulled apart the carb in my quad yet, but Ive ripped many apart and cleaned them, and they arent really that difficult. Im guessing you have a jet thats plugged.

Seafoam is wonderful stuff, but I dont think it would unplug a jet by adding it to your tank. I love the stuff though, I use it as a stabalizer and as a cleaner in lots of things around my farm.

i would definately drain your tank and clean your carb out. from it sitting over the winter the gas probably went bad. and it don t take much to get a carb dirty.

Honda shop told me to add stabilizer to the fuel and get a new gas can or fill it up at the pump. Also keep the tank full. I put a new carb in mine a couple weeks ago, after cleaning the old one. Runs like a champ now!

      Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?

      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!

      i just picked this up. was told ran fine but overheating issues led to replacing head gasket and head. has not ran since. he is not a mechanic but helped someone else who he could not get back to finish job, got aggravated and put up for sale. i was thinking timing issues. i have 110-120psi on all 3 cylinders so i think valves are correct. dont know about distributor yet. however i have no spark. i have no power going to ignition coil. tried to follow white wire but gets lost in wire harness. does anyone have a wiring diagram? can anyone tell me what conditions have to be met before starting. motor turns over so i would think all safeties are met but you never know.
