I know it sounds stupid but have you checked your battery ? Could be a dead cell that will show a little power. Also it could be your regulator/rectifier.  Take a tester when the bike is running and test the voltage at the battery during idle and rev it as well and see if it fluctuates on the tester.

Could be the starter relay, have you looked into all of the components of the electrical side of the bike. Check the relay and see what happens when you jump it. 
See if the engine cranks, there is also a neutral safety switch that you should look into as well. There are also other relays as well within the starting system so bottom line is your going to have to go part by part and check everything. If your not clear on how things work then feel free to ask.

      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.

      I've been trying to piece this Lakota 300 back together, slowly. It's been a rabbit hole however. I replace one thing, then it leads to replacing other things. Anyway, When I got this thing I noticed that the hose coming off the camshaft cover wasn't attached to anything, it was just hanging loose. (It's literally just a foot long hose attached to nothing) I figured since it was venting the head it would be ok and I am sure it is.
      However, last night I was looking at the service manual and noticed that it mentioned that this atv has a crankcase breather tube as well. Mine does not have one, so I looked at Partzilla and looked at the parts diagram and sure enough, it's definitely supposed to have one. The problem however is, the service manual does not show how it hooks up and the parts diagram only shows the exploded view of the assembly. I just find that kind of strange, nowhere in the manual does it show how it connects. Does it have it connector, attach to a nipple? It just doesn't say and it bothers me that there is a hole there without anything attached to it.  If anyone has a Bayou 300 or Lakota 300 with an intact breather vent system and could possibly take some clear photos of it or know how it connects I would be very grateful. I have searched high and low and cannot find any information on it.
       
      Thanks
