HI Nate!

A few things to check, 1. When you put the new flywheel on did you reinstall the woodruff key on the shaft its a little half moon shaped thing that goes on the cut out on the crank shaft its tricky to get on correctly?

2. If you removed the stator which is underneath the flywheel, and replaced the Phillips screws with allen heads, you may have to shave them down as I have seen a few heads too long and it get hung up.

3. make sure that all the coils on the stator are tight if a screw backed out it will allow a coil to move and it doesn't take much to hit the magnets.

4. Lastly with the flywheel off , give it a couple easy kicks and see if its binding with out the flywheel if so could be a bad rod bearing, or a ring snagging a port and not the flywheel at all or a few other things over in the tranny area.

Report back what ya find if anything, making a short vid or a couple pics can sometimes help to solve an issue!

Thanks, I got it working now i figured out that the screw holding stator on was sticking out to much and interfering. Just curious do you know size of the idle screw, because my carb seem to be missing it?

Thanks

The idle screw is located on the big silver box on top of the carb called the (TORS assembly), you can get to it by removing the seat. If that isnt the one you are referring to see the diagram in this link you should be able to order just about any piece there! Just click the drop down box and click on carb :wink:

      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.
