quadgod211 Posted July 27, 2009 Report Share Posted July 27, 2009 this problem has haunted me for 2 years now.... the motor in my sig and my old 358 cub both would not run unless my spark plugs was gapped at next to nothing like 0.005..nearly touching... the bike misses at top end bad unless i do this to the plugs..... it cuts out completely at around 8800 rpm my pick up coil is at 0.017 or what ever specs is and my timing was +11 on the 358 and +9 on the 421 and taylor made plug wires from jeff at fast both motors used the same exact stator,,coil,,,cdi and all..... this is racking my brain........ some one help me out.... matt Quote Link to comment Share on other sites More sharing options...

quadgod211 Posted July 28, 2009 Author Report Share Posted July 28, 2009 maybe this would help a lil.... does anyone know what closing the gap does..is it less fire..more fire...does it change timing alot???? matt Quote Link to comment Share on other sites More sharing options...
J-Madd Posted July 28, 2009 Report Share Posted July 28, 2009 CLosing the gap keeps the fuel from blowing out the spark, if that makes sense. Maybe your running way too rich? Maybe your stator is weak and cannot produce a spark strong enough to jump the normal 0.018'' or 0.020'' gap??? Quote Link to comment Share on other sites More sharing options...
Tedder Posted July 28, 2009 Report Share Posted July 28, 2009 On an ocilliscope you can see that it takes an initial surge or spike of electricity to jump the electrodes but once that gap is jumped the balance of the sustained kernal is at a much lower voltage. In my opinion your problem is likely in the ignition.... Quote Link to comment Share on other sites More sharing options...
quadgod211 Posted July 28, 2009 Author Report Share Posted July 28, 2009 i just found today that my stator has some bare spots in the wraps and looks real brittle and cracked all over....is there any goop or tape i can cover my stator in again???? matt Quote Link to comment Share on other sites More sharing options...

Electrical gremlins can be lots of fun. Quote Link to comment Share on other sites More sharing options...
quadgod211 Posted July 29, 2009 Author Report Share Posted July 29, 2009 the white hard goop over the coils are busted and chipped ...it has places were it shows the copper looking wire.. wouldn't i loose spark through the chipped spots????? plus thetops of the stator are wore really bad and copper is showing there to....... im gonna replace it with a old one on my shelf.....id like to find a new or used pvl before i buy a new yamaha stator.... matt Quote Link to comment Share on other sites More sharing options...
J-Madd Posted July 29, 2009 Report Share Posted July 29, 2009 PVL I gotta box full of pvl parts. If I wasn't still running a pvl on one, I'd sell all of the crap. Oh yeah, and a NEW oem stator is ridiculous$$$; and used oem stators seem to be scarce. Quote Link to comment Share on other sites More sharing options...

dajogejr Posted August 2, 2009 Report Share Posted August 2, 2009 Buy a used OEM stator. A pristine used one is gonna run you 50 to 100 bucks. It's worth it. DO NOT, I repeat, DO NOT buy from RM Stator, Ricky Stator or Rick's Motorsport. They're all the same, JUNK. PM minkia38 or email him at minkia38@gmail.com He's got parts laying around than Pamela Andersen's had dicks in her. Since it does it all the time, I don't think it's a coil or CDI. Usually, not all the time, a bad coil or CDI will act up when the bike is warmed up. You can ohm test a stator for starters, but I'd had a stator that Ohm'd good end up being bad as well. Crap shoot.

dajogejr Posted August 2, 2009 Report Share Posted August 2, 2009 I have always heard Moose stators were good. Last I checked, they were EXPENSIVE!! These are very reasonable to be honest. http://cgi.ebay.com/ebaymotors/MOOSE-IGNIT...sQ5fAccessories Quote Link to comment Share on other sites More sharing options...
quadgod211 Posted August 3, 2009 Author Report Share Posted August 3, 2009 well i swapped my stator out with a stator that came off a running motor i was working on for a customer...and still same thing..so im gonna rule that out the miss went away but i had to gap the plugs to .010 still dont know why though.. plug gap from .022 and further the bike wont even run.... from .022-.011 the bike revs fine but has the small miss like i 1st complain about from .011 down the bike doesnt miss runs great,,dles great should i play with the pick up coil and maybe run it closer and further and see if the plugs change????? also if my electrical system is weak like you all suggested does this mean my timing may say its +12 but really be at +7 or 8 matt Quote Link to comment Share on other sites More sharing options...

Have you messed with the coil at all? Remove the plug caps, trim the wire ends back 1/2 inch, and reconnect them. No...timing is timing.

quadgod211 Posted August 3, 2009 Author Report Share Posted August 3, 2009 i have the Taylor made wires that you jb weld into the stock coil...they could be burnt at the tips or something...you cant replace the caps on them there 1 piece designed... haven't fooled with the coil none ,,it was kinda loose on the frame and i tightened it up and it didn't affect anything though...... could it be my flywheel...it kinda has a rattle to it when you shake it ,,,nothing major just kinda feels like something might be loose....bike doesn't vibrate or anything... matt Quote Link to comment Share on other sites More sharing options...
