harleybeater Posted May 9, 2010 Author Report Share Posted May 9, 2010 update-... pulled the flywheel today and the woodruff key looked to be chipped on one end about an 8th of an inch and it kinda looked like it had wear marks like indents on both sides like it was out too far and the flywheel rotating and engine braking maybe put the grooves in them. but maybe i'm confused but even if the key was advanced or retarted, the spark should be intense correct? the stator and the ground on the stator looked good, didnt see any busted or rubbed wires. so i guess so far we've discovered it's not the cdi box, not the plugs, not the plug caps, pretty sure it's not the stator (yet), so next is to try my ignition coil on his. just double checking what i've done so far. soon as i get mine washed we'll switch coils. keep ya posted Quote Link to comment Share on other sites More sharing options...
harleybeater Posted May 9, 2010 Author Report Share Posted May 9, 2010 IMO...the most common thing to fail is the plug end caps and then the stator. You can completely remove/unplug the voltage regulator, just don't turn on your lights. That has NO effect on the ignition...it only prevent the bulbs from getting overjuiced and popping. Do you happen to have a Ricky Stator or aftermarket stator on that bike? original factory yamaha stator still installed on an '04 LE Quote Link to comment Share on other sites More sharing options...
harleybeater Posted May 26, 2010 Author Report Share Posted May 26, 2010 ok, couldn't get a woodruff key fast enough so we cleaned the stator with a rag just for kicks and put the flywheel back on with the old key. fit fine and went on strait but i'll still get another key. i put my working ignition coil on bro's quad and fired it up and STILL runs the same, weak spark and won't rev out. so we put his coil with new plug caps back on and STILL the same thing. we pulled off the wiring harness and removed all the tors wiring and the parking brake wire and check all the in-harness ground crimps and all ok. didn't see any rubbing and so i taped it back up and put it back in the bike. fired it up again and STILL the same thing. did another ohm check on the stator and the lighting coil was slightly higher than speck in the book but not by more than 10-15 ohms. the stator is the last thing that we havn't swapped from mine to his so he's going to buy a stator and a key and hope for the best i guess. anyone have any other ideas???

pr0blumz Posted May 26, 2010 Report Share Posted May 26, 2010 Major change in elevation? My thoughts exactly. Did you perform a leakdown test? Quote Link to comment Share on other sites More sharing options...
Duneman101 Posted May 26, 2010 Report Share Posted May 26, 2010 Mine was doing the exact same thing... the stator checking out fine, so i swapped it with my buddies. it cranking just fine now, i just got the new one in the mail yesterday. It is probably the stator. Quote Link to comment Share on other sites More sharing options...
AKheathen Posted May 27, 2010 Report Share Posted May 27, 2010 2- things.....first, if the key looks like that, then the flywheel has been running loose, probably about 10 degrees off, too, and not keeping good pickup gap. it will likely come loose again. you should check the tapers for square and make sure they are not glazed up. 2nd- do your lights flicker allot, and does the flywheel make any rattle when you shale it?

harleybeater Posted May 27, 2010 Author Report Share Posted May 27, 2010 My thoughts exactly. Did you perform a leakdown test? just curious, what will a leak down test prove electrically, or are you thinking it's possibly something else?

harleybeater Posted June 6, 2010 Author Report Share Posted June 6, 2010 all right.... got a brand new rm stator, not sure if there good or not, but i've kinda read not so good things about ricky stator so that's what made that decision..... anyway, installed the stator. took her out for a dive and it does EXACTLY THE SAME THING!!! RUNS LIKE CRAP!!! checked the resistance of all three coils on the stator and they're within specs. flywheel is find, sounds solid with no rattles. took the carbs off and cleaned them up, no plugged jets. took reeds cages off and checked for cracks in reeds.... no cracks. put it all back together and tested again and does the same crappy bog. just dont know what to do now. this is really chizzlin' me out bad not to mention my bro's pissed and like goin thru serious banshee depression...haha we gotta laugh, what else are we gonna do. i've read about the "smack test" of the cdi but i've not done it yet. here's a question. will a 2001 cdi box work with a 2004 le??? i just feel like i've looked at everything but i know i'm missing something..

xX JAMMER Xx Posted June 6, 2010 Report Share Posted June 6, 2010 have you checked to see if your wires got burnt by your stinger tube?? could of melted the wiring harness and is shorting out on your pipe. just an idea Quote Link to comment Share on other sites More sharing options...
harleybeater Posted June 6, 2010 Author Report Share Posted June 6, 2010 have you checked to see if your wires got burnt by your stinger tube?? could of melted the wiring harness and is shorting out on your pipe. just an idea no man.... took the whole harness of and looked for anything that resembled burnt or rubbed or cracked wires. even unplugged the kill switch and headlight connector where it's a six pin connector behind the radiator and started it thinking it could be in the switches but it wasnt.

harleybeater Posted June 8, 2010 Author Report Share Posted June 8, 2010 the only thing we haven't checked from my quad to his is the flywheel. even though his looks and sounds good with no rattles, could it possibly be it?? reguardless, that's next to be swapped hopefully sometime this week.

harleybeater Posted June 13, 2010 Author Report Share Posted June 13, 2010 ok,.. i give up!! swapped flywheels and nothin'... still crap. i'm so confused. i'm tryin to get a compression tester around to check that and then probably going to get the parts to do a leak down test. it almost sounded like it ran worse with my flywheel.
