DUH-DUT Posted May 10, 2009 Report Share Posted May 10, 2009 Rode the other day and it was fine. drove 10 miles down the road and it would not start. ohmed the stator and it was fine 119.8 and 19.8. it has spark at the plugs. the pickup coil is good on the gap. i can pull it and it will not start at a slow speed the faster i pull it the bike will fire and stay running until i pull in the clutch and it dies. i have changed the ignition coil and the cdi and it does the same thing. also completly clean the carbs and they are fine. My ? is the flywheel does not feel like it has a magnetic suction. i cn stick anything to it and nothing happens. Could my flywheel have all of a sudden lost its magnitism? Or any other suggestions would be appreciated. The flywheel is BRAND NEW for say, it has about 7hrs on it. Quote Link to comment Share on other sites More sharing options...
R. Rollins Posted May 10, 2009 Report Share Posted May 10, 2009 (edited) Man thats the wierdest one I have heard in a while to troubleshoot. Does it still have the TORS on it? Whats wierd is that it dies when you pull the clutch in on it. When you do get it running at an idle, are you able to rev it up while its in neutral? Just wondering? Also; How does it run without pulling in the clutch? Also; Have you checked the wiring harness for evidence of a wire rubbing through to ground to the frame or something? Edited May 10, 2009 by R.

lowbuckracing Posted May 10, 2009 Report Share Posted May 10, 2009 Pull your flywheel and make sure the woodriff key is not mangeld..If its dammaged you can still get spark but not run worth a crap..Also,did you do a compression test or check the spark plugs...Check the on and off switch also,make sure its clean..Check your grounds also..Make sure no wires rubbed through on the stator wire coming out against the flywheel..Good luck,JB Quote Link to comment Share on other sites More sharing options...

Also; How does it run without pulling in the clutch? Also; Have you checked the wiring harness for evidence of a wire rubbing through to ground to the frame or something? It does not have tors on it at all. it will not run at an idle i have to keep reving it up and it dies when i come to a stop to get the rope off the other bike. even if i keep reving it it will die. okay i go to pull start slow clutch out after moving, wide open throttle it sounds like a deep roar of air and fuel. like a k&n on a truck. the faster we pull it, it starts to fire and then it fires. pull in the clutch reving the bike up to keep it running and as soon as we slow down it dies. we also pulled it with me just holding the rope and got it started. as soon as i let go and put the bike under a load it dies.

banshee_terror_ Posted May 10, 2009 Report Share Posted May 10, 2009 if you cant stick any piece of metal to the flywheel like you said it lost its magnitism. then its your flywheel. idk how it did it but you need a new one. Quote Link to comment Share on other sites More sharing options...
DUH-DUT Posted May 10, 2009 Author Report Share Posted May 10, 2009 I just found out the guy that built the motor out a RS flywheel in? What would be a good one to buy? Quote Link to comment Share on other sites More sharing options...
AKheathen Posted May 10, 2009 Report Share Posted May 10, 2009 do your lights light up good while it's running? buy a stocker, if you can. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 10, 2009 Report Share Posted May 10, 2009 do your lights light up good while it's running? buy a stocker, if you can. I agree...I won't even keep RS stuff as a backup. Buy a stocker off NYUK or Minkia38 or fleabay. before you put it on, shake it by your ear to make sure the magnets inside aren't busted up.

R. Rollins Posted May 10, 2009 Report Share Posted May 10, 2009 WOW ....Those new flywheels are $381.00 new at Babbits. That will choke a person up a bit. Better get one off a running motor somewhere else. Quote Link to comment Share on other sites More sharing options...
DUH-DUT Posted May 11, 2009 Author Report Share Posted May 11, 2009 do your lights light up good while it's running? buy a stocker, if you can. I dont have any lights hooked up on the bike right now. Quote Link to comment Share on other sites More sharing options...
DUH-DUT Posted May 12, 2009 Author Report Share Posted May 12, 2009 okay now i got my flywheel off and the damn thang has magnitism on the back side. should a bolt stick to the tabs on the outside of the flywheel also? Quote Link to comment Share on other sites More sharing options...
DUH-DUT Posted May 13, 2009 Author Report Share Posted May 13, 2009 bump. could anything else be wrong maybe a clogged crankcase hose or something simple like that Quote Link to comment Share on other sites More sharing options...
AKheathen Posted May 13, 2009 Report Share Posted May 13, 2009 the nodes on the outside are just steel, not magnets. the magnets inside are pretty weak, so you might not feel them with anything bigger than a paperclip on the outside. a screwdriver should stick to the inside about every inch, evenly. they are placed in there in alternating polarity, to make power. did you ever verify that you are getting good blue spark when you casually kick it over? it's starting to sound like a fuel issue Quote Link to comment Share on other sites More sharing options...
