  1. replaced already

  2. Bad earth somewhere

  3. or have ya got a headlamp on it?

  4. Dont know, if i like you very much john

  5. Got enough friends. Merry Christmas, buy a Beta

  6. Ya Beta roll that throttle on lol

  7. Manualslib.com have a pdf service manual.
    Check the coil resistances in the stator.

  8. What sort of lighting kit are you running? it could have something to do with how much power the lights are drawing on start up

  9. Has no headlights on

  10. Are you sure the coil is good?

  11. and it's fine

  12. coil grounds?

  13. If you're sure the coil checks good and your stator and pickup test right, start looking for bad grounds.

  14. Also, if your only contribution is to tell the guy to buy your favorite brand, why not shut the fuck up? No one cares if you have a Beta. Or a Kawasaki, Suzuki, Yamaha, Honda, TM, AJP, BMW, Hodaka, Jawa, Bultaco, etc. Why do guys feel the urge to be douchebags here instead of either helping or scrolling by?

  15. Hey Brian C. Englund, your a real tough guy. Merry Christmas you you too. (Douche bag)

  16. I come here to learn and to help. I do a bit of both. You show up to be an asshole and waste dudes' time. Your mom or first grade teacher should have told you if you can't say something nice, don't say anything at all. Corollary is that if you can't say something useful in a mechanical discussion, shut your fucking trap and keep scrolling…or listen and learn.

  17. The orange vs. whatever teasing has been going on long before I became involved.
    Most just give it back and laugh.
    Someone must have pissed in this guy's eggnog

  18. I like some banter. I'll bullshit on Red vs Orange all day. But I won't waste a guy's time doing it on his question post. I'm generally already pretty damned frustrated when I finally ask for help, so the old “LOL, burn that shit and buy my favorite brand” crap is even more irritating.

  19. I disagree with you Brian

  20. It ran fine and then one day when i rode it just stopped running and saw that spark is weak

  21. Check your coil wire to plug and check your cdi

  22. Just making sure that he's checking correctly

  23. Dumb lesson learned the hard way, but check that the plug boot is properly seated onto the wire. If in doubt, it sometimes helps to unscrew it, clip 6mm or so off the wire, then screw it back in. Also, see that the little cap inside the boot is properly seating onto the nipple of the spark plug.

  24. had done that already.the coil wire's shock is not so hard as it must be

  25. Ok, so you will want to test your wiring at the terminations in it (connections,plugs, joins)' and if you start near the centre of the harness you can follow ether back toward the stator if there is no power or towards the plug if there is.

  26. Duan Do you follow what im saying there?
    When youve tested a spot, jump to the middle of whats left.

  27. Compression test?

  28. How's the compression mate

  29. Could still be your coil or stator. Ohm meter only puts tiny current through windings. Google :how does an ignition system work on a motorcycle.

  30. compression is very good

  31. I've changed staters on them even with good readings and coils ! And they have been the problem also 2013/15 also auto decompression system holding exhaust valves open slightly but giving a good compression reading , injectors and kill switches !

  32. Replaced the stator coil

  33. I'm just wondering how you know the spark is weak? Did you just sit the plug on the head and turn it over? Or measure it somehow?
