The smaller wires going to the starter relay, have you tried to disconnect them and see if the starter spins with the battery connected? The reasons  why this would happen are a few things.  The start button is stuck. That can be tested with an electrical tester.  The wire that sends 12v to the soliniod to activate the starter has been tapped into by another 12 v feed somewhere along the line. Maybe someone added an accessory of sort and that’s back feeding the wire.  

Are you at all handy with a tester ?

You will pick it up as you go.  It’s not that hard to understand once you have played with a few bikes.

      recently picked up some project bikes off CL for cheap.  got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start)  plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
      so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows.  things I see:  carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.

      i know this isnt an atv but same type of thing.  I have a riding mower im fixing and selling for my aunt and it has a dead battery.  i jumped it off my atv and when i turn the key nothing at all happens.  i tried jumping the relay still nothing.  this is with the seat down.  you wouldnt think this mower would have issues as its a top-of-the-line brand and almost brand new (aunt found it for a good price, still got tits on tires, just sat for a couple months in a mechanic shop

      I have a 1999 Sportsman  500, it was running fine, than started to lose power in the winter, I adjusted the idle screw and away I went, than a few weeks ago it died, I have found that i am flooding the engine, compression was at 70PSI and due to the compression release mech. i assume i am good as it compared to the same PSI on a 2000 sportsman 500 i have. i cannot start the atv unless i go full throttle and it starts an runs for about 30 sec than dies, again it is flooded. i ordered a new carb off ebay as i could get one for around $40. put that in same issue, i have checked the timing, (good), valves out of adjustment i adjusted to .006 still same issue, i have found the exhaust lobe and rocker arm to have some wear, i have ordered new ones, but am looking for any other input in this area as well. would the exhaust cam and rocker arm cause the engine to flood? i have used a bore scope and the piston liner has good cross hatching still? any input would be great.

      Not sure if this is the right place to ask this but I have. 2000 Honda Forman 450es that was my fathers. When he passed away I figured I’d put some work into it. It’s been setting a while but figured it would be a good project for me and my son  
      Just found out that the display speedometer has been discontinued and I’m having a hard time finding one on eBay  I was curious if anyone knew if any other year model would work on this bike ?
